3fb1581ea1 ARM: 8199/1: PM / Runtime: Add getter for querying the IRQ safe option v12
Add a simple getter pm_runtime_is_irq_safe() for querying whether runtime
PM IRQ safe was set or not.

Various bus drivers implementing runtime PM may use choose to suspend
differently based on IRQ safeness status of child driver (e.g. do not
unprepare the clock if IRQ safe is not set).

Some TI SoCs like DRA7 have a RAMINIT register specification
different from the other AMxx SoCs and as expected by the

To add more insanity, this register is shared with other

16b1d26e77 rtc/tpo: Driver to support rtc and wakeup on PowerNV platform
The patch implements the OPAL rtc driver that binds with the rtc
driver subsystem. The driver uses the platform device infrastructure
to probe the rtc device and register it to rtc class framework. The
'wakeup' is supported depending upon the property 'has-tpo' present
in the OF node. It provides a way to load the generic rtc driver in
in the absence of an OPAL driver.

The patch also moves the existing OPAL rtc get/set time interfaces to the
new driver and exposes the necessary OPAL calls using EXPORT_SYMBOL_GPL.

960fb622f8 net: provide a per host RSS key generic infrastructure
RSS (Receive Side Scaling) typically uses Toeplitz hash and a 40 or 52 bytes
RSS key.

Some drivers use a constant (and well known key), some drivers use a random
key per port, making bonding setups hard to tune. Well known keys increase
attack surface, considering that number of queues is usually a power of two.

This patch provides infrastructure to help drivers doing the right thing.

netdev_rss_key_fill() should be used by drivers to initialize their RSS key,
even if they provide ethtool -X support to let user redefine the key later.

A new /proc/sys/net/core/netdev_rss_key file can be used to get the host
RSS key even for drivers not providing ethtool -x support, in case some
applications want to precisely setup flows to match some RX queues.

Tested:

ca5a71de48 drm: Sanitize DRM_IOCTL_MODE_CREATE_DUMB input
Some drivers erroneously treat the .pitch and .size fields of struct
 drm_mode_create_dumb as inputs. While the include/uapi/drm/drm_mode.h
 header has a comment denoting them as outputs, that seemingly wasn't
 enough to make drivers use them properly.
 
 The result is that some userspace doesn't explicitly zero out those
 fields, assuming that the kernel won't use them. That causes problems
 since the data within the structure might be uninitialized, so bogus
 data may end up confusing drivers (ridiculously large values for the
 pitch, ...).
 
 This series attempts to improve the situation by fixing all drivers to
 not use the output fields. Furthermore to spare new drivers this bad
 surprise, the DRM core now zeros out these fields prior to handing the
 data structure to the driver.
 
 Lessons learned from this are that future IOCTLs should be properly
 documented (in the DRM DocBook for example) and should be rigorously
 defined. To prevent misuse like this, userspace should be required to
 zero out all output fields. The kernel should check for this and fail
 if that's not the case.

b0654103f5 drm/tegra: Changes for v3.19-rc1
The highlights in this pull request are:
 
   * IOMMU support: The Tegra DRM driver can now deal with discontiguous
     buffers if an IOMMU exists in the system. That means it can allocate
     using drm_gem_get_pages() and will map them into IOVA space via the
     IOMMU API. Similarly, non-contiguous PRIME buffers can be imported
     from a different driver, which allows better integration with gk20a
     (nouveau) and less hacks.
 
   * Universal planes: This is precursory work for atomic modesetting and
     will allow hardware cursor support to be implemented on pre-Tegra114
     where RGB cursors were not supported.
 
   * DSI ganged-mode support: The DSI controller can now gang up with a
     second DSI controller to drive high resolution DSI panels.
 
 Besides those bigger changes there is a slew of fixes, cleanups, plugged
 memory leaks and so on.

9bb5b20f5d dt-bindings: simplefb: Specify node location and handoff related properties
Since simplefb nodes do not relate directly to hw typically they have been
placed in the root of the devicetree. As the represent runtime information
having them as sub-nodes of /chosen is more logical, specify this.

Also specify when to set the chosen stdout-path property to a simplefb node.

For reliable handover to a hardware specific driver, that driver needs to
know which simplefb to unregister when taking over, specify how the hw driver
can find the matching simplefb node.

Last add some advice on how to fill and use simplefb nodes from a firmware
pov.

An underrun (playback) event occurs when the serializer transfer
data from the XRBUF buffer to the XRSR shift register, but the
XRBUF hasn't been filled. Similarly, the overrun (capture) event
occurs when data from the XRSR shift register is transferred to
the XRBUF but it hasn't been read yet.

These events are handled as XRUN events that cause the pcm to stop.
The stream has to be explicitly restarted by the userspace which
ensures that after stopping/starting McASP the data transfer is
aligned with DMA. The other possibility was to internally stop and
start McASP without DMA even knowing about it.

d92c0da71a IB/srp: Add multichannel support
Improve performance by using multiple RDMA/RC channels per SCSI
host for communication with an SRP target. About the
implementation:
- Introduce a loop over all channels in the code that uses
  target->ch.
- Set the SRP_MULTICHAN_MULTI flag during login for the creation
  of the second and subsequent channels.
- RDMA completion vectors are chosen such that RDMA completion
  interrupts are handled by the CPU socket that submitted the I/O
  request. As one can see in this patch it has been assumed if a
  system contains n CPU sockets and m RDMA completion vectors
  have been assigned to an RDMA HCA that IRQ affinity has been
  configured such that completion vectors [i*m/n..(i+1)*m/n) are
  bound to CPU socket i with 0 <= i < n.
- Modify srp_free_ch_ib() and srp_free_req_data() such that it
  becomes safe to invoke these functions after the corresponding
  allocation function failed.
- Add a ch_count sysfs attribute per target port.

c8b09f6fb6 scsi: don't set tagging state from scsi_adjust_queue_depth
Remove the tagged argument from scsi_adjust_queue_depth, and just let it
handle the queue depth.  For most drivers those two are fairly separate,
given that most modern drivers don't care about the SCSI "tagged" status
of a command at all, and many old drivers allow queuing of multiple
untagged commands in the driver.

Instead we start out with the ->simple_tags flag set before calling
->slave_configure, which is how all drivers actually looking at
->simple_tags except for one worke anyway.  The one other case looks
broken, but I've kept the behavior as-is for now.

Except for that we only change ->simple_tags from the ->change_queue_type,
and when rejecting a tag message in a single driver, so keeping this
churn out of scsi_adjust_queue_depth is a clear win.

Now that the usage of scsi_adjust_queue_depth is more obvious we can
also remove all the trivial instances in ->slave_alloc or ->slave_configure
that just set it to the cmd_per_lun default.

Allow a driver to ask for block layer tags by setting .use_blk_tags in the
host template, in which case it will always see a valid value in
request->tag, similar to the behavior when using blk-mq.  This means even
SCSI "untagged" commands will now have a tag, which is especially useful
when using a host-wide tag map.

125c99bc8b scsi: add new scsi-command flag for tagged commands
Currently scsi piggy backs on the block layer to define the concept
of a tagged command.  But we want to be able to have block-level host-wide
tags assigned even for untagged commands like the initial INQUIRY, so add
a new SCSI-level flag for commands that are tagged at the scsi level, so
that even commands without that set can have tags assigned to them.  Note
that this alredy is the case for the blk-mq code path, and this just lets
the old path catch up with it.

We also set this flag based upon sdev->simple_tags instead of the block
queue flag, so that it is entirely independent of the block layer tagging,
and thus always correct even if a driver doesn't use block level tagging
yet.

Also remove the old blk_rq_tagged; it was only used by SCSI drivers, and
removing it forces them to look for the proper replacement.

ba7a46f16d net: Convert LIMIT_NETDEBUG to net_dbg_ratelimited
Use the more common dynamic_debug capable net_dbg_ratelimited
and remove the LIMIT_NETDEBUG macro.

All messages are still ratelimited.

Some KERN_<LEVEL> uses are changed to KERN_DEBUG.

This may have some negative impact on messages that were
emitted at KERN_INFO that are not not enabled at all unless
DEBUG is defined or dynamic_debug is enabled.  Even so,
these messages are now _not_ emitted by default.

This also eliminates the use of the net_msg_warn sysctl
"/proc/sys/net/core/warnings".  For backward compatibility,
the sysctl is not removed, but it has no function.  The extern
declaration of net_msg_warn is removed from sock.h and made
static in net/core/sysctl_net_core.c

o Update the sysctl documentation
o Remove the embedded uses of pr_fmt
o Coalesce format fragments

Rather than maintaining a separate promote_threshold variable that we

With some tests this has a sizeable difference, because the old code
was too eager to demote blocks.  For example, device-mapper-test-suite's
git_extract_cache_quick test goes from taking 190 seconds, to 142

So here's my atomic series, finally all debugged&reviewed. Sean Paul has
done a full detailed pass over it all, and a lot of other people have
commented and provided feedback on some parts. Rob Clark also converted
msm over the w/e and seems happy. The only small thing is that Rob wants
to export the wait_for_vblank, which imo makes sense. Since there's other
stuff still to do I think we should apply Rob's patch (once it has grown
appropriate kerneldoc) later on top of this.

This is just the core<->driver interface plus a big pile of helpers. Short
recap of the main ideas:

- There are essentially three helper libraries in this patch set:

  * Transitional helpers to use the new plane callbacks for legacy plane
    updates and in the crtc helper's ->mode_set callback. These helpers are
    only temporarily used to convert drivers to atomic, but they allow a
    nice separation between changing the driver backend and switching to
    the atomic commit logic.

  * Legacy helpers to implement all the legacy driver entry points
    (page_flip, set_config, plane vfuncs) on top of the new atomic driver
    interface. These are completely driver agnostic. The reason for having
    the legacy support as helpers is that drivers can switch step-by-step.
    And they could e.g. even keep the legacy page_flip code around for some
    old platforms where converting to full-blown atomic isn't worth it.

  * Atomic helpers which implement the various new ->atomic_* driver
    interfaces in terms of the revised crtc helper and new plane helper
    hooks.

- The revised crtc helper implemenation essentially implements all the
  lessons learned in the i915 modeset rework (when using the atomic helpers
  only):

  * Enable/disable sequence for a given config are always the same and
    callbacks are always called in the same order. This contrast starkly
    with the crtc helpers, where the sequence of operations is heavily
    dependent on the previous config.

    One corollary of this is that if the configuration of a crtc only
    partially changes (e.g. a connector moves in a cloned config) the
    helper code will still disable/enable the full display pipeline. This
    is the only way to ensure that the enable/disable sequence is always
    the same.

  * It won't call disable or enable hooks more than once any more because
    it lost track of state, thanks to the atomic state tracking. And if
    drivers implement the ->reset hook properly (by either resetting the hw
    or reading out the hw state into the atomic structures) this even
    extends to the hardware state. So no more disable-me-harder kind of
    nonsense.

  * The only thing missing is the hw state readout/cross-check support, but
    if drivers have hw state readout support in their ->reset handlers it's
    simple to extend that to cross-check the hw state.

  * The crtc->mode_set callback is gone and its replacement only sets crtc
    timings and no longer updates the primary plane state. This way we can
    finally implement primary planes properly.

- The new plane helpers should be suitable enough for pretty much
  everything, and a perfect fit for hardware with GO bits. Even if they
  don't fit the atomic helper library is rather flexible and exports all
  the functions for the individual steps to drivers. So drivers can pick
  what matches and implement their own magic for everything else.

- A big difference compared to all previous atomic series is that this one
  doesn't implement async commit in a generic way. Imo driver requirements
  for that are too diverse to create anything reasonable sane which would
  actually work on a reasonable amount of different drivers. Also, we've
  never had a helper library for page_flips even, so it's really hard to
  know what might work and what's stupid without a bit of experience in the form
  of a few driver implementations.

  I think with the current flexibility for drivers to pick individual
  stages and existing helpers like drm_flip_queue it's rather easy though
  to implement proper async commit.

- There's a few other differences of minor importance to earlier atomic
  series:

  * Common/generic properties are parsed in the callers/core and not in
    drivers, and passed to drivers by directly setting the right members in
    atomic state structures. That greatly simplifies all the transitional
    and legacy helpers an removes a lot of boilerplate code.

  * There's no crazy trylock mode used for the async commit since these
    helpers don't do async commit. A simple ordered flip queue of atomic
    state updates should be sufficient for preventing concurrent hw access
    anyway, as long as synchronous updates stall correctly with e.g.
    flush_work_queue or similar function. Abusing locks to enforce ordering
    isn't a good idea imo anyway.

  * These helpers reuse the existing ->mode_fixup hooks in the atomic_check
    callback. Which means that drivers need to adapat and move a lot less code
    into their atomic_check callbacks.

Now this isn't everything needed in the drm core and helpers for full
atomic support. But it's enough to start with converting drivers, and
except for actually testing multiplane and multicrtc updates also enough to
implement full atomic updates. Still missing are:

- Per-plane locking. Since these helpers here encapsulate the locking
  completely this should be fairly easy to implement.

- fbdev support for atomic_check/commit, so that multi-pipe finally works
  sanely in fbcon.

- Adding and decoding shared/core properties. That just needs to be rebased
  from Rob's latest patch series, with minor adjustments so that the
  decoding happens in the core instead of in drivers.

- Actually adding the atomic ioctl. Again just rebasing Rob's latest patch
  should be all that's needed.

- Resolving how to deal with DPMS in atomic. Atomic is a good excuse to fix up
  the crazy semantics dpms currently has. I'm floating an RFC about this topic
  already.

- Finally I couldn't test connector/encoder stealing properly since my test
  vehicle here doesn't allow a connector on different crtcs. So drivers
  which support this might see some surprises in that area. There is no semantic
  change though in how encoder stealing and assignment works (or at least no
  intended one), so I think the risk is minimal.

As just mentioned I've done a fake conversion of an existing driver using
crtc helpers to debug the helper code and validate the smooth transition
approach. And that smooth transition was the really big motivation for
this. It seems to actually work and consists of 3 phases:

Phase 1: Rework driver backend for crtc/plane helpers

The requirement here is that universal plane support is already implement. If
universal plane support isn't implement yet it might be better though to just do
it as part of this phase, directly using the new plane helpers. There are two
big things to do:

- Split up the existing ->update/disable_plane hooks into check/commit
  hooks and extract the crtc-wide prep/flush parts (like setting/clearing
  GO bits).

- The other big change is to split the crtc->mode_set hook into the plane
  update (done using the plane helpers) and the crtc setup in a new
  ->mode_set_nofb hook.

When phase 1 is complete the driver implements all the new callbacks which
push the software state into hardware, but still using all the legacy entry
points and crtc helpers. The transitional helpers serve as impendance
mismatch here.

Phase 2: Rework state handling

This consists of rolling out the state handling helpers for planes, crtcs
and connectors and reviewing all ->mode_fixup and similar hooks to make
sure they don't depend upon implicit global state which might change in the
atomic world. Any such code must be moved into ->atomic_check functions which
just rely on the free-standing atomic state update structures.

This phase also adds a few small pieces of fixup code to make sure the
atomic state doesn't get out of sync in the legacy driver callbacks.

Phase 3: Roll out atomic support

Now it's just about replacing vfuncs with the ones provided by the helper
and filling out the small missing pieces (like atomic_check logic or async
commit support needed for page_flips). Due to the prep work in phase 1 no
changes to the driver backend functions should be required, and because of
the prep work in phase 2 atomic implementations can be rolled out
step-by-step. So if async commit ins't implemented yet page_flip can be
implemented with the legacy functions without wreaking havoc in the other
operations.

c76acf4dff irqchip: bcm7120-l2: Extend driver to support 64+ bit controllers
Most implementations of the bcm7120-l2 controller only have a single
32-bit enable word + 32-bit status word.  But some instances have added
more enable/status pairs in order to support 64+ IRQs (which are all
ORed into one parent IRQ input).  Make the following changes to allow
the driver to support this:

 - Extend DT bindings so that multiple words can be specified for the
   reg property, various masks, etc.

 - Add loops to the probe/handle functions to deal with each word
   separately

 - Allocate 1 generic-chip for every 32 IRQs, so we can still use the
   clr/set helper functions

 - Update the documentation

This uses one domain per bcm7120-l2 DT node.  If the DT node defines
multiple enable/status pairs (i.e. >=64 IRQs) then the driver will
create a single IRQ domain with 2+ generic chips.  Multiple generic chips
are required because the generic-chip code can only handle one
enable/status register pair per instance.

246246cbde drivers: base: support cpu cache information interface to userspace via sysfs
This patch adds initial support for providing processor cache information
to userspace through sysfs interface. This is based on already existing
implementations(x86, ia64, s390 and powerpc) and hence the interface is
intended to be fully compatible.

The main purpose of this generic support is to avoid further code
duplication to support new architectures and also to unify all the existing
different implementations.

This implementation maintains the hierarchy of cache objects which reflects
the system's cache topology. Cache devices are instantiated as needed as
CPUs come online. The cache information is replicated per-cpu even if they are
shared. A per-cpu array of cache information maintained is used mainly for
sysfs-related book keeping.

It also implements the shared_cpu_map attribute, which is essential for
enabling both kernel and user-space to discover the system's overall cache
topology.

This patch also add the missing ABI documentation for the cacheinfo sysfs
interface already, which is well defined and widely used.

Exynos7 I2S controller has no internal dma, supports more
no. of root clock sampling frequencies and has more no.of Rx
fifos to support 7.1CH recording in TDM mode. Due to more no.
of root clock frequency values some of the bit offsets got
shifted up by one. Also I2S1 on previous Samsung platforms
uses v3 dai type but on Exynos7 it is upgraded to v5 with
slightly modified register offsets for supporting more no.of
RFS values. Due to the above changes, the driver has to be
modified to handle all versions of I2S controller. For this
I introduced a new structure to hold modified bit offsets and
masks which is passed as dai data.

63692df103 PCI: Allow numa_node override via sysfs
NUMA systems with ACPI normally describe the physical topology via _PXM
methods.  But many BIOSes don't implement _PXM, which leaves the kernel
with no way to discover the device topology, which reduces performance
because we can't put memory and processes close to the device.

The NUMA node of a PCI device is already exported in the sysfs "numa_node"
file.  Make that file writable so users can workaround the lack of _PXM
methods in the BIOS.  For example:

  echo 3 > /sys/devices/pci0000:ff/0000:03:1f.3/numa_node

sets the node for PCI device 0000:03:1f.3.

Writing the file emits a FW_BUG warning to encourage users to request
firmware updates.  It also taints the kernel with TAINT_FIRMWARE_WORKAROUND
because overriding the node incorrectly can cause performance issues.

7c8ab967e3 serial: Fix locking for uart driver set_termios() method
The low-level uart driver may modify termios settings to override
settings that are not compatible with the uart, such as CRTSCTS.
Thus, callers of the low-level uart driver's set_termios() method must
hold termios_rwsem write lock to prevent concurrent access to termios,
in case such override occurs.

The termios_rwsem lock requirement does not extend to console setup
(ie., uart_set_options), as console setup cannot race with tty
operations. Nor does this lock requirement extend to functions which
cannot be concurrent with tty ioctls (ie., uart_port_startup() and
uart_resume_port()).

Further, always claim the port mutex to protect hardware
re-reprogramming in the set_termios() uart driver method. Note this
is unnecessary for console initialization in uart_set_options()
which cannot be concurrent with other uart operations.

9761536e1d debugfs: Have debugfs_print_regs32() return void
The seq_printf() will soon just return void, and seq_has_overflowed()
should be used instead to see if the seq can no longer accept input.

As the return value of debugfs_print_regs32() has no users and
the seq_file descriptor should be checked with seq_has_overflowed()
instead of return values of functions, it is better to just have
debugfs_print_regs32() also return void.

cc4ceb484b drm: Global atomic state handling
Some differences compared to Rob's patches again:
- Dropped the committed and checked booleans. Checking will be
  internally enforced by always calling ->atomic_check before
  ->atomic_commit. And async handling needs to be solved differently
  because the current scheme completely side-steps ww mutex deadlock
  avoidance (and so either reinvents a new deadlock avoidance wheel or
  like the current code just deadlocks).

- State for connectors needed to be added, since now they have a
  full-blown drm_connector_state (so that drivers have something to
  attach their own stuff to).

- Refcounting is gone. I plane to solve async updates differently,
  since the lock-passing scheme doesn't cut it (since it abuses ww
  mutexes). Essentially what we need for async is a simple ownership
  transfer from the caller to the driver. That doesn't need full-blown
  refcounting.

- The acquire ctx is a pointer. Real atomic callers should have that
  on their stack, legacy entry points need to put the right one
  (obtained by drm_modeset_legacy_acuire_ctx) in there.

- I've dropped all hooks except check/commit. All the begin/end
  handling is done by core functions and is the same.

- commit/check are just thin wrappers that ensure that ->check is
  always called.

- To help out with locking in the legacy implementations I've added a
  helper to just grab all locks in the backoff case.

v2: Add notices that check/commit can fail with EDEADLK.

v3:
- More consistent naming for state_alloc.
- Add state_clear which is needed for backoff and retry.

v4: Planes/connectors can switch between crtcs, and we need to be
careful that we grab the state (and locks) for both the old and new
crtc. Improve the interface functions to ensure this.

v5: Add functions to grab affected connectors for a crtc and to recompute
the crtc->enable state. This is useful for both helper and atomic ioctl
code when e.g. removing a connector.

v6: Squash in fixup from Fengguang to use ERR_CAST.

v7: Add debug output.

v8: Make checkpatch happy about kcalloc argument ordering.

v9: Improve kerneldoc in drm_crtc.h

v10:
- Fix another kcalloc argument misorder I've missed.
- More polish for kerneldoc.

v11: Clarify the ownership rules for the state object. The new rule is
that a successful drm_atomic_commit (whether synchronous or asnyc)
always inherits the state and is responsible for the clean-up. That
way async and sync ->commit functions are more similar.

v12: A few bugfixes:
- Assign state->state pointers correctly when grabbing state objects -
  we need to link them up with the global state.
- Handle a NULL crtc in set_crtc_for_plane to simplify code flow a bit
  for the callers of this function.

v13: Review from Sean:
- kerneldoc spelling fixes
- Don't overallocate states->planes.
- Handle NULL crtc in set_crtc_for_connector.

v14: Sprinkle __must_check over all functions which do wait/wound
locking to make sure callers don't forget this. Since I have ;-)

v15: Be more explicit in the kerneldoc when functions can return
-EDEADLK what to do. And that every other -errno is fatal.

v16: Indent with tabs instead of space, spotted by Ander.

v17: Review from Thierry, small kerneldoc and other naming polish.

0d9a693cc8 gpio / ACPI: Add support for _DSD device properties
With release of ACPI 5.1 and _DSD method we can finally name GPIOs (and
other things as well) returned by _CRS. Previously we were only able to
use integer index to find the corresponding GPIO, which is pretty error
prone if the order changes.

With _DSD we can now query GPIOs using name instead of an integer index,
like the below example shows:

  // Bluetooth device with reset and shutdown GPIOs
  Device (BTH)
  {
      Name (_HID, ...)

      Name (_CRS, ResourceTemplate ()
      {
          GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
                  "\\_SB.GPO0", 0, ResourceConsumer) {15}
          GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
                  "\\_SB.GPO0", 0, ResourceConsumer) {27, 31}
      })

      Name (_DSD, Package ()
      {
          ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
          Package ()
	  {
              Package () {"reset-gpio", Package() {^BTH, 1, 1, 0 }},
              Package () {"shutdown-gpio", Package() {^BTH, 0, 0, 0 }},
          }
      })
  }

The format of the supported GPIO property is:

  Package () { "name", Package () { ref, index, pin, active_low }}

  ref - The device that has _CRS containing GpioIo()/GpioInt() resources,
        typically this is the device itself (BTH in our case).
  index - Index of the GpioIo()/GpioInt() resource in _CRS starting from zero.
  pin - Pin in the GpioIo()/GpioInt() resource. Typically this is zero.
  active_low - If 1 the GPIO is marked as active_low.

Since ACPI GpioIo() resource does not have field saying whether it is
active low or high, the "active_low" argument can be used here. Setting
it to 1 marks the GPIO as active low.

In our Bluetooth example the "reset-gpio" refers to the second GpioIo()
resource, second pin in that resource with the GPIO number of 31.

This patch implements necessary support to gpiolib for extracting GPIOs
using _DSD device properties.

f5914908a5 ALSA: pcm: Replace PCM hwptr tracking with tracepoints
ALSA PCM core has a mechanism tracking the PCM hwptr updates for
analyzing XRUNs.  But its log is limited (up to 10) and its log output
is a kernel message, which is hard to handle.

In this patch, the hwptr logging is moved to the tracing
infrastructure instead of its own.  Not only the hwptr updates but
also XRUN and hwptr errors are recorded on the trace log, so that user
can see such events at the exact timing.

The new "snd_pcm" entry will appear in the tracing events:
  # ls -F /sys/kernel/debug/tracing/events/snd_pcm
  enable  filter  hw_ptr_error/  hwptr/  xrun/

The hwptr is for the regular hwptr update events.  An event trace
looks like:

  aplay-26187 [004] d..3  4012.834761: hwptr: pcmC0D0p/sub0: POS: pos=488, old=0, base=0, period=1024, buf=16384

"POS" shows the hwptr update by the explicit position update call and
"IRQ" means the hwptr update by the interrupt,
i.e. snd_pcm_period_elapsed() call.  The "pos" is the passed
ring-buffer offset by the caller, "old" is the previous hwptr, "base"
is the hwptr base position, "period" and "buf" are period- and
buffer-size of the target PCM substream.
(Note that the hwptr position displayed here isn't the ring-buffer
 offset.  It increments up to the PCM position boundary.)

The XRUN event appears similarly, but without "pos" field.
The hwptr error events appear with the PCM identifier and its reason
string, such as "Lost interrupt?".

The XRUN and hwptr error reports on kernel message are still left, can
be turned on/off via xrun_debug proc like before.  But the bit 3, 4, 5
and 6 bits of xrun_debug proc are dropped by this patch.  Also, along
with the change, the message strings have been reformatted to be a bit
more consistent.

Last but not least, the hwptr reporting is enabled only when
CONFIG_SND_PCM_XRUN_DEBUG is set.

460d098cb6 usb: dwc3: make HIRD threshold configurable
HIRD threshold should be configurable by different platforms.

From DesignWare databook:
When HIRD_Threshold[4] is set to 1b1 and HIRD value is greater than or
equal to the value in HIRD_Threshold[3:0], dwc3 asserts output signals
utmi_l1_suspend_n to put PHY into Deep Low-Power mode in L1.

When HIRD_Threshold[4] is set to 1b0 or the HIRD value is less than
HIRD_Threshold[3:0], dwc3 asserts output signals utmi_sleep_n on L1.

7f05db6a20 kvm: drop unsupported capabilities, fix documentation
No kernel ever reported KVM_CAP_DEVICE_MSIX, KVM_CAP_DEVICE_MSI,
KVM_CAP_DEVICE_ASSIGNMENT, KVM_CAP_DEVICE_DEASSIGNMENT.

This makes the documentation wrong, and no application ever
written to use these capabilities has a chance to work correctly.
The only way to detect support is to try, and test errno for ENOTTY.
That's unfortunate, but we can't fix the past.

Document the actual semantics, and drop the definitions from
the exported header to make it easier for application
developers to note and fix the bug.

Pull networking fixes from David Miller:
 "A bit has accumulated, but it's been a week or so since my last batch
  of post-merge-window fixes, so...

   1) Missing module license in netfilter reject module, from Pablo.
      Lots of people ran into this.

   2) Off by one in mac80211 baserate calculation, from Karl Beldan.

   3) Fix incorrect return value from ax88179_178a driver's set_mac_addr
      op, which broke use of it with bonding.  From Ian Morgan.

   4) Checking of skb_gso_segment()'s return value was not all
      encompassing, it can return an SKB pointer, a pointer error, or
      NULL.  Fix from Florian Westphal.

      This is crummy, and longer term will be fixed to just return error
      pointers or a real SKB.

   6) Encapsulation offloads not being handled by
      skb_gso_transport_seglen().  From Florian Westphal.

   7) Fix deadlock in TIPC stack, from Ying Xue.

   8) Fix performance regression from using rhashtable for netlink
      sockets.  The problem was the synchronize_net() invoked for every
      socket destroy.  From Thomas Graf.

   9) Fix bug in eBPF verifier, and remove the strong dependency of BPF
      on NET.  From Alexei Starovoitov.

  10) In qdisc_create(), use the correct interface to allocate
      ->cpu_bstats, otherwise the u64_stats_sync member isn't
      initialized properly.  From Sabrina Dubroca.

  11) Off by one in ip_set_nfnl_get_byindex(), from Dan Carpenter.

  12) nf_tables_newchain() was erroneously expecting error pointers from
      netdev_alloc_pcpu_stats().  It only returna a valid pointer or
      NULL.  From Sabrina Dubroca.

  13) Fix use-after-free in _decode_session6(), from Li RongQing.

  14) When we set the TX flow hash on a socket, we mistakenly do so
      before we've nailed down the final source port.  Move the setting
      deeper to fix this.  From Sathya Perla.

  15) NAPI budget accounting in amd-xgbe driver was counting descriptors
      instead of full packets, fix from Thomas Lendacky.

  16) Fix total_data_buflen calculation in hyperv driver, from Haiyang
      Zhang.

  17) Fix bcma driver build with OF_ADDRESS disabled, from Hauke
      Mehrtens.

  18) Fix mis-use of per-cpu memory in TCP md5 code.  The problem is
      that something that ends up being vmalloc memory can't be passed
      to the crypto hash routines via scatter-gather lists.  From Eric
      Dumazet.

  19) Fix regression in promiscuous mode enabling in cdc-ether, from
      Olivier Blin.

  20) Bucket eviction and frag entry killing can race with eachother,
      causing an unlink of the object from the wrong list.  Fix from
      Nikolay Aleksandrov.

  21) Missing initialization of spinlock in cxgb4 driver, from Anish
      Bhatt.

  22) Do not cache ipv4 routing failures, otherwise if the sysctl for
      forwarding is subsequently enabled this won't be seen.  From
      Nicolas Cavallari"

7d2911c438 net: smc91x: Fix gpios for device tree based booting
With legacy booting, the platform init code was taking care of
the configuring of GPIOs. With device tree based booting, things
may or may not work depending what bootloader has configured or
if the legacy platform code gets called.

Let's add support for the pwrdn and reset GPIOs to the smc91x
driver to fix the issues of smc91x not working properly when
booted in device tree mode.

And let's change n900 to use these settings as some versions
of the bootloader do not configure things properly causing
errors.

This reverts commit 68da166491.

It turns out that the assertion about scope of regressions due to
always keeping keyboard controller in legacy mode was proven wrong.
There are laptops, such as Clevo W650SH, that only have internal
touchpad (no external PS/2 ports), that require active multiplexing
mode to switch the touchpad (Elantech) into native mode instead of
basic PS/2 emulation.

2071d0968e Documentation: gpio: guidelines for bindings
Now that ACPI supports named GPIO properties, either through ACPI 5.1 or
the per-driver ACPI GPIO mappings, we can be more narrow about the way
GPIOs should be specified in Device Tree bindings.

This patch updates the GPIO DT bindings documentation to highlight the
following rules for new GPIO bindings:

- All new bindings must have a meaningful name (e.g. the "gpios"
  property must not be used)
- The only suffix allowed is "-gpios", no matter the number of
  descriptors in the property
- GPIOs can only be grouped under the same property when they serve the
  same purpose, a case that should remain exceptional (e.g. bit-banged
  data lines).

The return values of seq_printf/puts/putc are frequently misused.

Start down a path to remove all the return value uses of these
functions.

Move the seq_overflow() to a global inlined function called
seq_has_overflowed() that can be used by the users of seq_file() calls.

Update the documentation to not show return types for seq_printf
et al.  Add a description of seq_has_overflowed().

7fd2561e4e net: ipv6: Add a sysctl to make optimistic addresses useful candidates
Add a sysctl that causes an interface's optimistic addresses
to be considered equivalent to other non-deprecated addresses
for source address selection purposes.  Preferred addresses
will still take precedence over optimistic addresses, subject
to other ranking in the source address selection algorithm.

This is useful where different interfaces are connected to
different networks from different ISPs (e.g., a cell network
and a home wifi network).

The current behaviour complies with RFC 3484/6724, and it
makes sense if the host has only one interface, or has
multiple interfaces on the same network (same or cooperating
administrative domain(s), but not in the multiple distinct
networks case.

For example, if a mobile device has an IPv6 address on an LTE
network and then connects to IPv6-enabled wifi, while the wifi
IPv6 address is undergoing DAD, IPv6 connections will try use
the wifi default route with the LTE IPv6 address, and will get
stuck until they time out.

Also, because optimistic nodes can receive frames, issue
an RTM_NEWADDR as soon as DAD starts (with the IFA_F_OPTIMSTIC
flag appropriately set).  A second RTM_NEWADDR is sent if DAD
completes (the address flags have changed), otherwise an
RTM_DELADDR is sent.

Also: add an entry in ip-sysctl.txt for optimistic_dad.

While testing upcoming Yaogong patch (converting out of order queue

Reordering level was limited to 127 for no good reason, and some
network setups [1] can easily reach this limit and get limited
throughput.

Allow a new max limit of 300, and add a sysctl to allow admins to even
allow bigger (or lower) values if needed.

The CONFIG_RCU_CPU_STALL_VERBOSE Kconfig parameter causes preemptible
RCU's CPU stall warnings to dump out any preempted tasks that are blocking
the current RCU grace period.  This information is useful, and the default
has been CONFIG_RCU_CPU_STALL_VERBOSE=y for some years.  It is therefore
time for this commit to remove this Kconfig parameter, so that future
kernel builds will always act as if CONFIG_RCU_CPU_STALL_VERBOSE=y.

Commit adb19fb66e (Documentation: add makefiles for more targets) is
now building this by default, so it's failing the kernel build entirely.

Switching the declaration from uint64_t to time_t does the right thing

5345c1d417 ptp: restore the makefile for building the test program.
This patch brings back the makefile called testptp.mk which was removed
in commit adb19fb66e (Documentation: add makefiles for more targets).

While the idea of that commit was to improve build coverage of the
examples, the new Makefile is unable to cross compile the testptp program.
In contrast, the deleted makefile was able to do this just fine.

This patch fixes the regression by restoring the original makefile.

- Fix for a recent PCI power management change that overlooked
    the fact that some IRQ chips might not be able to configure
    PCIe PME for system wakeup from Lucas Stach.
 
  - Fix for a bug introduced in 3.17 where acpi_device_wakeup()

  - A bunch of intel_pstate driver fixes (all -stable candidates)
    from Dirk Brandewie, Gabriele Mazzotta and Pali Rohár.
 
  - Fixes for a rather long-standing problem with the OOM killer
    and the freezer that frozen processes killed by the OOM do
    not actually release any memory until they are thawed, so
    OOM-killing them is rather pointless, with a couple of
    cleanups on top (Michal Hocko, Cong Wang, Rafael J Wysocki).
 
  - ACPICA update to upstream release 20140926, inlcuding mostly
    cleanups reducing differences between the upstream ACPICA and
    the kernel code, tools changes (acpidump, acpiexec) and
    support for the _DDN object (Bob Moore, Lv Zheng).
 
  - New PM QoS class for memory bandwidth from Tomeu Vizoso.
 
  - Default 32-bit DMA mask for platform devices enumerated by ACPI

 "This is material that didn't make it to my 3.18-rc1 pull request for
  various reasons, mostly related to timing and travel (LinuxCon EU /
  LPC) plus a couple of fixes for recent bugs.

  The only really new thing here is the PM QoS class for memory
  bandwidth, but it is simple enough and users of it will be added in
  the next cycle.  One major change in behavior is that platform devices
  enumerated by ACPI will use 32-bit DMA mask by default.  Also included
  is an ACPICA update to a new upstream release, but that's mostly
  cleanups, changes in tools and similar.  The rest is fixes and
  cleanups mostly.

  Specifics:

   - Fix for a recent PCI power management change that overlooked the
     fact that some IRQ chips might not be able to configure PCIe PME
     for system wakeup from Lucas Stach.

   - Fix for a bug introduced in 3.17 where acpi_device_wakeup() is
     called with a wrong ordering of arguments from Zhang Rui.

   - A bunch of intel_pstate driver fixes (all -stable candidates) from
     Dirk Brandewie, Gabriele Mazzotta and Pali Rohár.

   - Fixes for a rather long-standing problem with the OOM killer and
     the freezer that frozen processes killed by the OOM do not actually
     release any memory until they are thawed, so OOM-killing them is
     rather pointless, with a couple of cleanups on top (Michal Hocko,
     Cong Wang, Rafael J Wysocki).

   - ACPICA update to upstream release 20140926, inlcuding mostly
     cleanups reducing differences between the upstream ACPICA and the
     kernel code, tools changes (acpidump, acpiexec) and support for the
     _DDN object (Bob Moore, Lv Zheng).

   - New PM QoS class for memory bandwidth from Tomeu Vizoso.

   - Default 32-bit DMA mask for platform devices enumerated by ACPI
     (this change is mostly needed for some drivers development in
     progress targeted at 3.19) from Heikki Krogerus.

   - ACPI EC driver cleanups, mostly related to debugging, from Lv
     Zheng.

   - cpufreq-dt driver updates from Thomas Petazzoni.

   - powernv cpuidle driver update from Preeti U Murthy"

8264fce6de Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management updates from Zhang Rui:
 "Sorry that I missed the merge window as there is a bug found in the
  last minute, and I have to fix it and wait for the code to be tested
  in linux-next tree for a few days.  Now the buggy patch has been
  dropped entirely from my next branch.  Thus I hope those changes can
  still be merged in 3.18-rc2 as most of them are platform thermal
  driver changes.

  Specifics:

   - introduce ACPI INT340X thermal drivers.

     Newer laptops and tablets may have thermal sensors and other
     devices with thermal control capabilities that are exposed for the
     OS to use via the ACPI INT340x device objects.  Several drivers are
     introduced to expose the temperature information and cooling
     ability from these objects to user-space via the normal thermal
     framework.

     From: Lu Aaron, Lan Tianyu, Jacob Pan and Zhang Rui.

   - introduce a new thermal governor, which just uses a hysteresis to
     switch abruptly on/off a cooling device.  This governor can be used
     to control certain fan devices that can not be throttled but just
     switched on or off.  From: Peter Feuerer.

   - introduce support for some new thermal interrupt functions on
     i.MX6SX, in IMX thermal driver.  From: Anson, Huang.

   - introduce tracing support on thermal framework.  From: Punit
     Agrawal.

   - small fixes in OF thermal and thermal step_wise governor"

Pull SCSI target updates from Nicholas Bellinger:
 "Here are the target updates for v3.18-rc2 code.  These where
  originally destined for -rc1, but due to the combination of travel
  last week for KVM Forum and my mistake of taking the three week merge
  window literally, the pull request slipped..  Apologies for that.

  Things where reasonably quiet this round.  The highlights include:

   - New userspace backend driver (target_core_user.ko) by Shaohua Li
     and Andy Grover
   - A number of cleanups in target, iscsi-taret and qla_target code
     from Joern Engel
   - Fix an OOPs related to queue full handling with CHECK_CONDITION
     status from Quinn Tran
   - Fix to disable TX completion interrupt coalescing in iser-target,
     that was causing problems on some hardware
   - Fix for PR APTPL metadata handling with demo-mode ACLs

  I'm most excited about the new backend driver that uses UIO + shared
  memory ring to dispatch I/O and control commands into user-space.
  This was probably the most requested feature by users over the last
  couple of years, and opens up a new area of development + porting of
  existing user-space storage applications to LIO.  Thanks to Shaohua +
  Andy for making this happen.

  Also another honorable mention, a new Xen PV SCSI driver was merged
  via the xen/tip.git tree recently, which puts us now at 10 target
  drivers in upstream! Thanks to David Vrabel + Juergen Gross for their
  work to get this code merged"

The A80 SoC has 12 PLL clocks, 3 AHB clocks, 2 APB clocks, and a

the processor cores, memory and various busses. Also there is a
bus clock for a ARM CCI400 module.

As far as I can tell, the GT bus and CCI400 bus clock must be
protected.

This patch adds driver support for peripheral related PLLs and
bus clocks on the A80. The GT and CCI400 clocks are added as well
as these 2 along with the PLLs they are clocked from must not be
disabled.

  Probably the most interesting fix is the sys_call_table one, which
  enables syscall tracing for powerpc.  There's a fix for HMI handling
  for old firmware, more endian fixes for firmware interfaces, more EEH
  fixes, Anton fixed our routine that gets the current stack pointer,
  and a few other misc bits"

When posting a patch series that includes both code implementing a
Device Tree binding and its associated documentation, the DT docs
should come in the series before the implementation.

This not only avoids checkpatch.pl to complain about undocumented
bindings but also makes the review process easier.

Document this convention since it may not be obvious.

a8e0aead70 documentation: memory-barriers: clarify relaxed io accessor semantics
This patch extends the paragraph describing the relaxed read io accessors
so that the relaxed accessors are defined to be:

 - Ordered with respect to each other if accessing the same peripheral

 - Unordered with respect to normal memory accesses

 - Unordered with respect to LOCK/UNLOCK operations

Whilst many architectures will provide stricter semantics, ARM, Alpha and
PPC can achieve significant performance gains by taking advantage of some
or all of the above relaxations.

9c261f89a3 ARM: firmware: Introduce suspend and resume operations
This patch extends the firmware_ops structure with two new callbacks:
.suspend() and .resume(). The former is intended to ask the firmware to
save all its volatile state and suspend the system, without returning
back to the kernel in between. The latter is to be called early by
very low level platform suspend code after waking up to restore low
level hardware state, which can't be restored in non-secure mode.

While at it, outdated version of the structure is removed from the
documentation and replaced with a reference to the header file.

   - Improve callchains when using libunwind (Namhyung Kim)

  Tooling fixes and infrastructure changes:

   - Fix for double free in 'perf stat' when using some specific invalid
     command line combo (Yasser Shalabi)

   - Fix off-by-one bugs in map->end handling (Stephane Eranian)

   - Fix off-by-one bug in maps__find(), also related to map->end
     handling (Namhyung Kim)

   - Make struct symbol->end be the first addr after the symbol range,
     to make it match the convention used for struct map->end.  (Arnaldo
     Carvalho de Melo)

   - Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat
     live' (Jiri Olsa)

   - Fix python test build by moving callchain_param to an object linked
     into the python binding (Jiri Olsa)

   - Document sysfs events/ interfaces (Cody P Schafer)

   - Fix typos in perf/Documentation (Masanari Iida)

   - Add missing 'struct option' forward declaration (Arnaldo Carvalho
     de Melo)

   - Add option to copy events when queuing for sorting across cpu
     buffers and enable it for 'perf kvm stat live', to avoid having
     events left in the queue pointing to the ring buffer be rewritten
     in high volume sessions.  (Alexander Yarygin, improving work done
     by David Ahern):

   - Do not include a struct hists per perf_evsel, untangling the
     histogram code from perf_evsel, to pave the way for exporting a
     minimalistic tools/lib/api/perf/ library usable by tools/perf and
     initially by the rasd daemon being developed by Borislav Petkov,
     Robert Richter and Jean Pihet.  (Arnaldo Carvalho de Melo)

   - Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and
     thread maps mean syswide monitoring, reducing the boilerplate for
     tools that only want system wide mode.  (Arnaldo Carvalho de Melo)

   - Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete
     should be just a front end for exit + free (Arnaldo Carvalho de
     Melo)

   - Add support to new style format of kernel PMU event.  (Kan Liang)

Pull core block layer changes from Jens Axboe:
 "This is the core block IO pull request for 3.18.  Apart from the new
  and improved flush machinery for blk-mq, this is all mostly bug fixes
  and cleanups.

   - blk-mq timeout updates and fixes from Christoph.

   - Removal of REQ_END, also from Christoph.  We pass it through the
     ->queue_rq() hook for blk-mq instead, freeing up one of the request
     bits.  The space was overly tight on 32-bit, so Martin also killed
     REQ_KERNEL since it's no longer used.

   - blk integrity updates and fixes from Martin and Gu Zheng.

   - Update to the flush machinery for blk-mq from Ming Lei.  Now we
     have a per hardware context flush request, which both cleans up the
     code should scale better for flush intensive workloads on blk-mq.

   - Improve the error printing, from Rob Elliott.

   - Backing device improvements and cleanups from Tejun.

   - Fixup of a misplaced rq_complete() tracepoint from Hannes.

   - Make blk_get_request() return error pointers, fixing up issues
     where we NULL deref when a device goes bad or missing.  From Joe
     Lawrence.

   - Prep work for drastically reducing the memory consumption of dm
     devices from Junichi Nomura.  This allows creating clone bio sets
     without preallocating a lot of memory.

   - Fix a blk-mq hang on certain combinations of queue depths and
     hardware queues from me.

   - Limit memory consumption for blk-mq devices for crash dump
     scenarios and drivers that use crazy high depths (certain SCSI
     shared tag setups).  We now just use a single queue and limited
     depth for that"

836a241832 ARM: expand fixmap region to 3MB
With commit a05e54c103 ("ARM: 8031/2: change fixmap mapping region to
support 32 CPUs"), the fixmap region was expanded to 2MB, but it
precluded any other uses of the fixmap region. In order to support other
uses the fixmap region needs to be expanded beyond 2MB. Fortunately, the
adjacent 1MB range 0xffe00000-0xfff00000 is availabe.

Remove fixmap_page_table ptr and lookup the page table via the virtual
address so that the fixmap region can span more that one pmd. The 2nd
pmd is already created since it is shared with the vector page.

VDDD, so document this properly.

Not passing VDDA and VDDIO prevents the driver to probe successfully.

 	* Change in the IOMMU-API to convert the former iommu_domain_capable
 	  function to just iommu_capable
 
 	* Various fixes in handling RMRR ranges for the VT-d driver (one fix
 	  requires a device driver core change which was acked
 	  by Greg KH)
 
 	* The AMD IOMMU driver now assigns and deassigns complete alias groups
 	  to fix issues with devices using the wrong PCI request-id
 
 	* MMU-401 support for the ARM SMMU driver
 
 	* Multi-master IOMMU group support for the ARM SMMU driver
 
 	* Various other small fixes all over the place

c0fa2373f8 The clk tree changes for 3.18 are dominated by clock drivers. Mostly
fixes and enhancements to existing drivers as well as new drivers. This
 tag contains a bit more arch code than I usually take due to some OMAP2+
 changes. Additionally it contains the restart notifier handlers which
 are merged as a dependency into several trees.
 
 The PXA changes are the only messy part. Due to having a stable tree I
 had to revert one patch and follow up with one more fix near the tip of
 this tag. Some dead code is introduced but it will soon become live code
 after 3.18-rc1 is released as the rest of the PXA family is converted
 over to the common clock framework.
 
 Another trend in this tag is that multiple vendors have started to push
 the complexity of changing their CPU frequency into the clock driver,
 whereas this used to be done in CPUfreq drivers.
 
 Changes to the clk core include a generic gpio-clock type and a
 clk_set_phase() function added to the top-level clk.h api. Due to some
 confusion on the fbdev mailing list the kernel boot parameters
 documentation was updated to further explain the clk_ignore_unused
 parameter, which is often required by users of the simplefb driver.
 Finally some fixes to the locking around the clock debugfs stuff was
 done to prevent deadlocks when interacting with other subsystems.

53b26b9bc9 stmmac: dwmac-sti: review the glue-logic for STi4xx and STiD127 SoCs
This patch is to review the whole glue logic adopted on STi SoCs that
was bugged.

In the old glue-logic there was a lot of confusion when setup the
retiming especially for STiD127 where, for example, the bits 6 and 7
(in the GMAC  control register) have a different meaning of what is
used for STiH4xx SoCs. So we cannot adopt the same glue for all these
SoCs.
Moreover, GiGa on STiD127 didn't work and, for all the SoCs, the RGMII
couldn't run when the speed was 10Mbps (because the clock was not properly
managed).
Note that the phy clock needs to be provided by the platform as well as
documented in the related binding file (updated as consequence).

The old code supported too many configurations never adopted and validated.
This made the code very complex to maintain and debug in case of issues.

The patch simplifies all the configurations as commented in the tables
inside the file and obviously it has been tested on all the boards
based on the SoCs mentioned.

With this patch, the dwmac-sti is also ready to support new configurations that
will be available on next SoC generations.

 "This patch set contains the main portion of the changes for 3.18 in
  regard to the s390 architecture.  It is a bit bigger than usual,
  mainly because of a new driver and the vector extension patches.

  The interesting bits are:
   - Quite a bit of work on the tracing front.  Uprobes is enabled and
     the ftrace code is reworked to get some of the lost performance
     back if CONFIG_FTRACE is enabled.
   - To improve boot time with CONFIG_DEBIG_PAGEALLOC, support for the
     IPTE range facility is added.
   - The rwlock code is re-factored to improve writer fairness and to be
     able to use the interlocked-access instructions.
   - The kernel part for the support of the vector extension is added.
   - The device driver to access the CD/DVD on the HMC is added, this
     will hopefully come in handy to improve the installation process.
   - Add support for control-unit initiated reconfiguration.
   - The crypto device driver is enhanced to enable the additional AP

additional format letters.

For example, if the given buffer is:

b03023ecbd coredump: add %i/%I in core_pattern to report the tid of the crashed thread
format_corename() can only pass the leader's pid to the core handler,
but there is no simple way to figure out which thread originated the
coredump.

As Jan explains, this also means that there is no simple way to create
the backtrace of the crashed process:

As programs are mostly compiled with implicit gcc -fomit-frame-pointer
one needs program's .eh_frame section (equivalently PT_GNU_EH_FRAME
segment) or .debug_frame section.  .debug_frame usually is present only
in separate debug info files usually not even installed on the system.
While .eh_frame is a part of the executable/library (and it is even
always mapped for C++ exceptions unwinding) it no longer has to be
present anywhere on the disk as the program could be upgraded in the
meantime and the running instance has its executable file already
unlinked from disk.

One possibility is to echo 0x3f >/proc/*/coredump_filter and dump all
the file-backed memory including the executable's .eh_frame section.
But that can create huge core files, for example even due to mmapped
data files.

Other possibility would be to read .eh_frame from /proc/PID/mem at the
core_pattern handler time of the core dump.  For the backtrace one needs
to read the register state first which can be done from core_pattern
handler:

    ptrace(PTRACE_SEIZE, tid, 0, PTRACE_O_TRACEEXIT)
    close(0);    // close pipe fd to resume the sleeping dumper
    waitpid();   // should report EXIT
    PTRACE_GETREGS or other requests

The remaining problem is how to get the 'tid' value of the crashed
thread.  It could be read from the first NT_PRSTATUS note of the core
file but that makes the core_pattern handler complicated.

Unfortunately %t is already used so this patch uses %i/%I.

Automatic Bug Reporting Tool (https://github.com/abrt/abrt/wiki/overview)
is experimenting with this.  It is using the elfutils
(https://fedorahosted.org/elfutils/) unwinder for generating the
backtraces.  Apart from not needing matching executables as mentioned
above, another advantage is that we can get the backtrace without saving
the core (which might be quite large) to disk.

df9e26d093 rtc: s3c: add support for RTC of Exynos3250 SoC
Add support for RTC of Exynos3250 SoC.  The Exynos3250 needs source
clock(32.768KHz) for RTC block.  If source clock of RTC is registerd on
clock list of common clk framework, Exynos RTC drvier have to control
this clock.

Clock list for s3c-rtc device:
- rtc : CLK_RTC of CLK_GATE_IP_PERIR is gate clock for RTC.
- rtc_src : XrtcXTI is 32.768.kHz source clock for RTC.
 (XRTCXTI: Specifies a clock from 32.768 kHz crystal pad with XRTCXTI and
 XRTCXTO pins. RTC uses this clock as the source of a real-time clock.)

bbaecc0882 binfmt_misc: expand the register format limit to 1920 bytes
The current code places a 256 byte limit on the registration format.
This ends up being fairly limited when you try to do matching against a
binary format like ELF:

 - the magic & mask formats cannot have any embedded NUL chars
   (string_unescape_inplace halts at the first NUL)
 - each escape sequence quadruples the size: \x00 is needed for NUL
 - trying to match bytes at the start of the file as well as further
   on leads to a lot of \x00 sequences in the mask
 - magic & mask have to be the same length (when decoded)
 - still need bytes for the other fields
 - impossible!

Let's look at a concrete (and common) example: using QEMU to run MIPS
ELFs.  The name field uses 11 bytes "qemu-mipsel".  The interp uses 20
bytes "/usr/bin/qemu-mipsel".  The type & flags takes up 4 bytes.  We
need 7 bytes for the delimiter (usually ":").  We can skip offset.  So
already we're down to 107 bytes to use with the magic/mask instead of
the real limit of 128 (BINPRM_BUF_SIZE).  If people use shell code to
register (which they do the majority of the time), they're down to ~26
possible bytes since the escape sequence must be \x##.

The ELF format looks like (both 32 & 64 bit):

	e_ident: 16 bytes
	e_type: 2 bytes
	e_machine: 2 bytes

Those 20 bytes are enough for most architectures because they have so few
formats in the first place, thus they can be uniquely identified.  That
also means for shell users, since 20 is smaller than 26, they can sanely
register a handler.

But for some targets (like MIPS), we need to poke further.  The ELF fields
continue on:

	e_entry: 4 or 8 bytes
	e_phoff: 4 or 8 bytes
	e_shoff: 4 or 8 bytes
	e_flags: 4 bytes

We only care about e_flags here as that includes the bits to identify
whether the ELF is O32/N32/N64.  But now we have to consume another 16
bytes (for 32 bit ELFs) or 28 bytes (for 64 bit ELFs) just to match the
flags.  If every byte is escaped, we send 288 more bytes to the kernel
((20 {e_ident,e_type,e_machine} + 12 {e_entry,e_phoff,e_shoff} + 4
{e_flags}) * 2 {mask,magic} * 4 {escape}) and we've clearly blown our
budget.

Even if we try to be clever and do the decoding ourselves (rather than
relying on the kernel to process \x##), we still can't hit the mark --
string_unescape_inplace treats mask & magic as C strings so NUL cannot
be embedded.  That leaves us with having to pass \x00 for the 12/24
entry/phoff/shoff bytes (as those will be completely random addresses),
and that is a minimum requirement of 48/96 bytes for the mask alone.
Add up the rest and we blow through it (this is for 64 bit ELFs):
magic: 20 {e_ident,e_type,e_machine} + 24 {e_entry,e_phoff,e_shoff} +
       4 {e_flags} = 48              # ^^ See note below.
mask: 20 {e_ident,e_type,e_machine} + 96 {e_entry,e_phoff,e_shoff} +
       4 {e_flags} = 120
Remember above we had 107 left over, and now we're at 168.  This is of
course the *best* case scenario -- you'll also want to have NUL bytes
in the magic & mask too to match literal zeros.

Note: the reason we can use 24 in the magic is that we can work off of the
fact that for bytes the mask would clobber, we can stuff any value into
magic that we want.  So when mask is \x00, we don't need the magic to also
be \x00, it can be an unescaped raw byte like '!'.  This lets us handle
more formats (barely) under the current 256 limit, but that's a pretty
tall hoop to force people to jump through.

With all that said, let's bump the limit from 256 bytes to 1920.  This way
we support escaping every byte of the mask & magic field (which is 1024
bytes by themselves -- 128 * 4 * 2), and we leave plenty of room for other
fields.  Like long paths to the interpreter (when you have source in your
/really/long/homedir/qemu/foo).  Since the current code stuffs more than
one structure into the same buffer, we leave a bit of space to easily
round up to 2k.  1920 is just as arbitrary as 256 ;).

c2426d2ad5 ima: added support for new kernel cmdline parameter ima_template_fmt
This patch allows users to provide a custom template format through the
new kernel command line parameter 'ima_template_fmt'. If the supplied
format is not valid, IMA uses the default template descriptor.

Changelog:
 - v3:
   - added check for 'fields' and 'num_fields' in
     template_desc_init_fields() (suggested by Mimi Zohar)

 - v2:
   - using template_desc_init_fields() to validate a format string
     (Roberto Sassu)
   - updated documentation by stating that only the chosen template
     descriptor is initialized (Roberto Sassu)

 - v1:
   - simplified code of ima_template_fmt_setup()
     (Roberto Sassu, suggested by Mimi Zohar)

2d73bae12b powerpc/numa: Add ability to disable and debug topology updates
We have hit a few customer issues with the topology update code (VPHN
and PRRN). It would be nice to be able to debug the notifications coming
from the hypervisor in both cases to the LPAR, as well as to disable
responding to the notifications at boot-time, to narrow down the source
of the problems. Add a basic level of such functionality, similar to the
numa= command-line parameter. We already have a toggle in
/proc/powerpc/topology_updates that allows run-time enabling/disabling,
so the updates can be started at run-time if desired. But the bugs we've
run into have occured during boot or very shortly after coming to login,
and have resulted in a broken NUMA topology.

68da166491 Input: i8042 - disable active multiplexing by default
Active multiplexing is a nice feature as it allows several pointing devices
(such as touchpad and external mouse) use their native protocols at the
same time. Unfortunately many manufacturers do not implement the feature
properly even though they advertise it. The problematic implementations are
never fixed, since Windows by default does not use this mode, and move from
one BIOS/model of laptop to another. When active multiplexing is broken
turning it on usually results in touchpad, keyboard, or both unresponsive.

With PS/2 usage on decline (most of PS/2 devices in use nowadays are
internal laptop touchpads), I expect number of users who have laptops with
working MUX implementation, docking stations with external PS/2 ports, and
who are still using external PS/2 mice, to be rather small. Let's flip the
default to be OFF and allow activating it through i8042.nomux=0 kernel
option.  We'll also keep DMI table where we can record known good models.

e98d6e7f76 Devicetree changes for v3.18
This branch contains bug fixes and new features for the devicetree code.
 Most of the changes are either new testcases for the selftest code or
 documentation changes. The most notable change is the addition of a
 phandle resolver for use when grafting in a second device tree blob into
 the core tree. The resolver isn't currently used by anything other than
 the selftest module, but it will be used to support device tree
 overlays; probably in the v3.19 timeframe.
 
 Also note that I've moved my normal tree from git.secretlab.ca to
 git.kernel.org.

a2ce35273c sound updates for 3.18-rc1
This time it's a relatively calm update batch, but the amount isn't
 too small in the end.  Here we go over some highlights:
 
 - ALSA core
   - One major change is the support of nonatomic PCM operations.
     This allows the trigger and other callbacks to call schedule(),
     which would be useful for mailbox type communications.  Already
     some drivers (Digigram ones) have been converted to use together
     with threaded irqs as an example.
   - Improvement / fixes of DSD PCM format support
 
 - HD-audio
   - Large volume of rewrites are found in Realtek codec driver for
     converting Dell and HP quirks to generic forms.
   - Inverted dmic code cleanup from David.
   - Realtek COEF access has been optimized.
   - Now HD-audio jack infrastructure allows multiple callbacks, which
     fixes / simplifies the jack-dependent power controls on STAC/IDT
     and VIA codecs.
   - Many additional device-specific fixups as usual
   - A few deadcode cleanups, CA0132 code cleanup, etc.
 
 - ASoC
   - More componentization work from Lars-Peter, this time mainly
     cleaning up the suspend and bias level transition callbacks.
   - Real system support for the Intel drivers and a bunch of fixes
     and enhancements for the associated CODEC drivers, this is going
     to need a lot quirks over time due to the lack of any firmware
     description of the boards.
   - Jack detect support for simple card from Dylan Reid.
   - A bunch of small fixes and enhancements for the Freescale
     drivers.
   - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32,
     Everest Semiconductor ES8328 and Freescale cards using the ASRC
     in newer i.MX processors.
   - A few simple-card fixes, mostly cleanups but also a fix for
   - interaction between GPIO 0 and simple-card.
 
 - Misc
   - Virtuoso / Oxygen updates by Clemens
   - USB-audio: Yamaha MOTIF XF MIDI port name fixes
   - Conversion of kernel messages to standard dev_*() in ctxfi
     driver.

Pull libata update from Tejun Heo:
 "AHCI is getting per-port irq handling and locks for better
  scalability.  The gain is not huge but measureable with multiple high
  iops devices connected to the same host; however, the value of
  threaded IRQ handling seems negligible for AHCI and it likely will
  revert to non-threaded handling soon.

  Another noteworthy change is George Spelvin's "libata: Un-break ATA
  blacklist".  During 3.17 devel cycle, the libata blacklist glob
  matching got generalized and rewritten; unfortunately, the patch
  forgot to swap arguments to match the new match function and ended up
  breaking blacklist matching completely.  It got noticed only a couple
  days ago so it couldn't make for-3.17-fixes either.  :(

  Other than the above two, nothing too interesting - the usual cleanup
  churns and device-specific changes"

015254daf1 zram: use notify_free to account all free notifications
`notify_free' device attribute accounts the number of slot free
notifications and internally represents the number of zram_free_page()
calls.  Slot free notifications are sent only when device is used as a
swap device, hence `notify_free' is used only for swap devices.  Since
f4659d8e62 (zram: support REQ_DISCARD) ZRAM handles yet another one
free notification (also via zram_free_page() call) -- REQ_DISCARD
requests, which are sent by a filesystem, whenever some data blocks are
discarded.  However, there is no way to know the number of notifications
in the latter case.

Use `notify_free' to account the number of pages freed by
zram_bio_discard() and zram_slot_free_notify().  Depending on usage
scenario `notify_free' represents:

 a) the number of pages freed because of slot free notifications, which is
   equal to the number of swap_slot_free_notify() calls, so there is no
   behaviour change

 b) the number of pages freed because of REQ_DISCARD notifications

461a8eee6a zram: report maximum used memory
Normally, zram user could get maximum memory usage zram consumed via
polling mem_used_total with sysfs in userspace.

But it has a critical problem because user can miss peak memory usage
during update inverval of polling.  For avoiding that, user should poll it
with shorter interval(ie, 0.0000000001s) with mlocking to avoid page fault
delay when memory pressure is heavy.  It would be troublesome.

This patch adds new knob "mem_used_max" so user could see the maximum
memory usage easily via reading the knob and reset it via "echo 0 >
/sys/block/zram0/mem_used_max".

Since zram has no control feature to limit memory usage, it makes hard to
manage system memrory.

This patch adds new knob "mem_limit" via sysfs to set up the a limit so
that zram could fail allocation once it reaches the limit.

In addition, user could change the limit in runtime so that he could
manage the memory more dynamically.

Initial state is no limit so it doesn't break old behavior.

1f13ae399c mm: remove noisy remainder of the scan_unevictable interface
The deprecation warnings for the scan_unevictable interface triggers by
scripts doing `sysctl -a | grep something else'.  This is annoying and not
helpful.

The interface has been defunct since 264e56d824 ("mm: disable user
interface to manually rescue unevictable pages"), which was in 2011, and
there haven't been any reports of usecases for it, only reports that the
deprecation warnings are annying.  It's unlikely that anybody is using
this interface specifically at this point, so remove it.

ed2f240094 memory-hotplug: add sysfs valid_zones attribute
Currently memory-hotplug has two limits:

1. If the memory block is in ZONE_NORMAL, you can change it to
   ZONE_MOVABLE, but this memory block must be adjacent to ZONE_MOVABLE.

2. If the memory block is in ZONE_MOVABLE, you can change it to
   ZONE_NORMAL, but this memory block must be adjacent to ZONE_NORMAL.

With this patch, we can easy to know a memory block can be onlined to
which zone, and don't need to know the above two limits.

Updated the related Documentation.

b528392669 ACPI and power management updates for 3.18-rc1
- Rework the handling of wakeup IRQs by the IRQ core such that
    all of them will be switched over to "wakeup" mode in
    suspend_device_irqs() and in that mode the first interrupt
    will abort system suspend in progress or wake up the system
    if already in suspend-to-idle (or equivalent) without executing
    any interrupt handlers.  Among other things that eliminates the
    wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
    flag with interrupts which don't really need it and should not
    use it (Thomas Gleixner and Rafael J Wysocki).
 
  - Switch over ACPI to handling wakeup interrupts with the help
    of the new mechanism introduced by the above IRQ core rework
    (Rafael J Wysocki).
 
  - Rework the core generic PM domains code to eliminate code that's
    not used, add DT support and add a generic mechanism by which
    devices can be added to PM domains automatically during
    enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
 
  - Add debugfs-based mechanics for debugging generic PM domains
    (Maciej Matraszek).
 
  - ACPICA update to upstream version 20140828.  Included are updates
    related to the SRAT and GTDT tables and the _PSx methods are in
    the METHOD_NAME list now (Bob Moore and Hanjun Guo).
 
  - Add _OSI("Darwin") support to the ACPI core (unfortunately, that
    can't really be done in a straightforward way) to prevent
    Thunderbolt from being turned off on Apple systems after boot
    (or after resume from system suspend) and rework the ACPI Smart
    Battery Subsystem (SBS) driver to work correctly with Apple
    platforms (Matthew Garrett and Andreas Noever).
 
  - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
    code, adding support for 133MHz I2C source clock on Intel Baytrail
    to it and making it avoid using UART RTS override with Auto Flow
    Control (Heikki Krogerus).
 
  - ACPI backlight updates removing the video_set_use_native_backlight
    quirk which is not necessary any more, making the code check the
    list of output devices returned by the _DOD method to avoid
    creating acpi_video interfaces that won't work and adding a quirk
    for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).
 
  - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).
 
  - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
    Sudip Mukherjee, Yijing Wang, and Zhang Rui).
 
  - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
    Rasmus Villemoes).
 
  - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name
    change among other things), ppc-corenet, powernv (Viresh Kumar,
    Preeti U Murthy, Shilpasri G Bhat, Lucas Stach).
 
  - cpuidle support for DT-based idle states infrastructure, new
    ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi,
    Rasmus Villemoes).
 
  - ARM big.LITTLE cpuidle driver updates: support for DT-based
    initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
    Kevin Hilman).
 
  - Rework of the test_suspend kernel command line argument and
    a new trace event for console resume (Srinivas Pandruvada,
    Todd E Brandt).
 
  - Second attempt to optimize swsusp_free() (hibernation core) to
    make it avoid going through all PFNs which may be way too slow on
    some systems (Joerg Roedel).
 
  - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
 
  - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS
    entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman).
 
  - PM core fix related to clock management (Geert Uytterhoeven).
 
  - PM core's sysfs code cleanup (Johannes Berg).

Merge tag 'pm+acpi-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "Features-wise, to me the most important this time is a rework of
  wakeup interrupts handling in the core that makes them work
  consistently across all of the available sleep states, including
  suspend-to-idle.  Many thanks to Thomas Gleixner for his help with
  this work.

  Second is an update of the generic PM domains code that has been in
  need of some care for quite a while.  Unused code is being removed, DT
  support is being added and domains are now going to be attached to
  devices in bus type code in analogy with the ACPI PM domain.  The
  majority of work here was done by Ulf Hansson who also has been the
  most active developer this time.

  Apart from this we have a traditional ACPICA update, this time to
  upstream version 20140828 and a few ACPI wakeup interrupts handling
  patches on top of the general rework mentioned above.  There also are
  several cpufreq commits including renaming the cpufreq-cpu0 driver to
  cpufreq-dt, as this is what implements generic DT-based cpufreq
  support, and a new DT-based idle states infrastructure for cpuidle.

  In addition to that, the ACPI LPSS driver is updated, ACPI support for
  Apple machines is improved, a few bugs are fixed and a few cleanups
  are made all over.

  Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
  maintained by Kevin Hilman that will be merged through the PM tree.

  Numbers-wise, the generic PM domains update takes the lead this time
  with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
  place goes to the wakeup interrupts handling rework (13 commits).

  Specifics:

   - Rework the handling of wakeup IRQs by the IRQ core such that all of
     them will be switched over to "wakeup" mode in suspend_device_irqs()

ea584595fc This is the bulk of GPIO changes for the v3.18 development
cycle:
 
 - Increase the default ARCH_NR_GPIO from 256 to 512. This
   was done to avoid having a custom <asm/gpio.h> header for
   the x86 architecture - GPIO is custom and complicated
   enough as it is already! We want to move to a radix to
   store the descriptors going forward, and finally get rid
   of this fixed array size altogether.
 
 - Endgame patching of the gpio_remove() semantics initiated
   by Abdoulaye Berthe. It is not accepted by the system that
   the removal of a GPIO chip fails during e.g. reboot or
   shutdown, and therefore the return value has now painfully
   been refactored away. For special cases like GPIO expanders
   on a hot-pluggable bus like USB, we may later add some
   gpiochip_try_remove() call, but for the cases we have now,
   return values are moot.
 
 - Some incremental refactoring of the gpiolib core and ACPI
   GPIO library for more descriptor usage.
 
 - Refactor the chained IRQ handler set-up method to handle
   also threaded, nested interrupts and set up the parent IRQ
   correctly. Switch STMPE and TC3589x drivers to use this
   registration method.
 
 - Add a .irq_not_threaded flag to the struct gpio_chip, so
   that also GPIO expanders that block but are still not
   using threaded IRQ handlers.
 
 - New drivers for the ARM64 X-Gene SoC GPIO controller.
 
 - The syscon GPIO driver has been improved to handle the
   "DSP GPIO" found on the TI Keystone 2 SoC:s.
 
 - ADNP driver switched to use gpiolib irqchip helpers.
 
 - Refactor the DWAPB driver to support being instantiated
   from and MFD cell (platform device).
 
 - Incremental feature improvement in the Zynq, MCP23S08,
   DWAPB, OMAP, Xilinx and Crystalcove drivers.
 
 - Various minor fixes.

whole kernel history.

Pull networking updates from David Miller:
 "Most notable changes in here:

   1) By far the biggest accomplishment, thanks to a large range of
      contributors, is the addition of multi-send for transmit.  This is
      the result of discussions back in Chicago, and the hard work of
      several individuals.

      Now, when the ->ndo_start_xmit() method of a driver sees
      skb->xmit_more as true, it can choose to defer the doorbell
      telling the driver to start processing the new TX queue entires.

      skb->xmit_more means that the generic networking is guaranteed to
      call the driver immediately with another SKB to send.

      There is logic added to the qdisc layer to dequeue multiple
      packets at a time, and the handling mis-predicted offloads in
      software is now done with no locks held.

      Finally, pktgen is extended to have a "burst" parameter that can
      be used to test a multi-send implementation.

      Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
      virtio_net

      Adding support is almost trivial, so export more drivers to
      support this optimization soon.

      I want to thank, in no particular or implied order, Jesper
      Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
      Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
      David Tat, Hannes Frederic Sowa, and Rusty Russell.

   2) PTP and timestamping support in bnx2x, from Michal Kalderon.

   3) Allow adjusting the rx_copybreak threshold for a driver via
      ethtool, and add rx_copybreak support to enic driver.  From
      Govindarajulu Varadarajan.

   4) Significant enhancements to the generic PHY layer and the bcm7xxx
      driver in particular (EEE support, auto power down, etc.) from
      Florian Fainelli.

   5) Allow raw buffers to be used for flow dissection, allowing drivers
      to determine the optimal "linear pull" size for devices that DMA
      into pools of pages.  The objective is to get exactly the
      necessary amount of headers into the linear SKB area pre-pulled,
      but no more.  The new interface drivers use is eth_get_headlen().
      From WANG Cong, with driver conversions (several had their own
      by-hand duplicated implementations) by Alexander Duyck and Eric
      Dumazet.

   6) Support checksumming more smoothly and efficiently for
      encapsulations, and add "foo over UDP" facility.  From Tom
      Herbert.

   7) Add Broadcom SF2 switch driver to DSA layer, from Florian
      Fainelli.

   8) eBPF now can load programs via a system call and has an extensive
      testsuite.  Alexei Starovoitov and Daniel Borkmann.

   9) Major overhaul of the packet scheduler to use RCU in several major
      areas such as the classifiers and rate estimators.  From John
      Fastabend.

  10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
      Duyck.

  11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
      Dumazet.

  12) Add Datacenter TCP congestion control algorithm support, From
      Florian Westphal.

  13) Reorganize sk_buff so that __copy_skb_header() is significantly
      faster.  From Eric Dumazet"

d5935b07da ARM64: SoC changes for 3.18
Starting with 3.18, we are merging SoC-specific changes for arm64 through
 the arm-soc tree, like we have been doing for arm32.
 
 This time, there is only one set of changes, adding support for the
 Cavium "Thunder" Soc family. Since the changes are relatively small,
 this includes Kconfig, defconfig and DT changes.
 
 If all goes well, we will never require adding actual C source code
 for platform support in arm64, given that the architecture is more
 clearly defined and we have moved out a lot of the platform specifics
 into device drivers for arm32 already.

8b45bc892e ARM: SoC driver updates for 3.18
These are changes for drivers that are intimately tied to some SoC
 and for some reason could not get merged through the respective
 subsystem maintainer tree.
 
 Most of the new code is for the Keystone Navigator driver, which is
 new base support that is going to be needed for their hardware
 accelerated network driver and other units.
 
 Most of the commits are for moving old code around from at91 and omap
 for things that are done in device drivers nowadays.
 
 - at91: move reset, poweroff, memory and clocksource code into drivers
   directories
 - socfpga: add edac driver (through arm-soc, as requested by Boris)
 - omap: move omap-intc code to drivers/irqchip
 - sunxi: added an RTC driver for sun6i
 - omap: mailbox driver related changes
 - keystone: support for the "Navigator" component
 - versatile: new reboot, led and soc drivers

b9af5643fd Staging patches for 3.18-rc1
Here is the big staging patch set for 3.18-rc1.
 
 Once again, we are deleting more code than we added, with something like
 150000 lines deleted overall.  Some of this is due to drivers being
 added to the networking tree, so the old versions are removed here, but
 even then, the overall difference is quite good.
 
 Other than driver deletions, lots and lots and lots of minor cleanups
 all over the place.  Full details are in the shortlog below.

e4e65676f2 Fixes and features for 3.18.
Apart from the usual cleanups, here is the summary of new features:
 
 - s390 moves closer towards host large page support
 
 - PowerPC has improved support for debugging (both inside the guest and
   via gdbstub) and support for e6500 processors
 
 - ARM/ARM64 support read-only memory (which is necessary to put firmware
   in emulated NOR flash)
 
 - x86 has the usual emulator fixes and nested virtualization improvements
   (including improved Windows support on Intel and Jailhouse hypervisor
   support on AMD), adaptive PLE which helps overcommitting of huge guests.
   Also included are some patches that make KVM more friendly to memory
   hot-unplug, and fixes for rare caching bugs.
 
 Two patches have trivial mm/ parts that were acked by Rik and Andrew.
 
 Note: I will soon switch to a subkey for signing purposes.  To verify

This time around most of the changes are a lot of new drivers along with
 the standard set of fixes and cleanups (thanks again largely to Axel
 Lin).  We do have one nice new feature in the core which factors out the
 disappointingly tricky code around DT parsing, only a couple of drivers
 have been converted so far:
 
  - Factor out the code for parsing the standard bindings for a set of
    regulators out of DT, making the probe part of a lot of drivers
    simplier.
  - New drivers for Dialog DA9213, HiSilicon HI6420, Intersil ISL9305/H,
    Ricoh RN5T618, Rockchip RK808, Skyworks SKY81452, Silergy SYR82x, and

c831dd7352 regmap: Updates for v3.18
The main update this time around is the addition of a standard DT
 binding for specifying the endianness of devices.  This allows drivers
 to support any endianness of device register map without any code,
 useful for configurable IP blocks.
 
 There's also a few bug fixes that I didn't get round to sending, none of
 them terribly severe or new, and a reduction in size for struct regmap.

c45198eda2 locks: move freeing of leases outside of i_lock
There was only one place where we still could free a file_lock while
holding the i_lock -- lease_modify. Add a new list_head argument to the
lm_change operation, pass in a private list when calling it, and fix
those callers to dispose of the list once the lock has been dropped.

e6f5c78930 locks: plumb a "priv" pointer into the setlease routines
In later patches, we're going to add a new lock_manager_operation to
finish setting up the lease while still holding the i_lock.  To do
this, we'll need to pass a little bit of info in the fcntl setlease
case (primarily an fasync structure). Plumb the extra pointer into
there in advance of that.

We declare this pointer as a void ** to make it clear that this is
private info, and that the caller isn't required to set this unless
the lm_setup specifically requires it.

====================
pull request: wireless-next 2014-10-03

Please pull tihs batch of updates intended for the 3.18 stream!

For the iwlwifi bits, Emmanuel says:

"I have here a few things that depend on the latest mac80211's changes:
RRM, TPC, Quiet Period etc...  Eyal keeps improving our rate control
and we have a new device ID. This last patch should probably have
gone to wireless.git, but at that stage, I preferred to send it to
-next and CC stable."

For (most of) the Atheros bits, Kalle says:

"The only new feature is testmode support from me. Ben added a new method
to crash the firmware with an assert for debug purposes. As usual, we
have lots of smaller fixes from Michal. Matteo fixed a Kconfig
dependency with debugfs. I fixed some warnings recently added to
checkpatch."

For the NFC bits, Samuel says:

"We've had major updates for TI and ST Microelectronics drivers, and a
few NCI related changes.

For TI's trf7970a driver:

- Target mode support for trf7970a
- Suspend/resume support for trf7970a
- DT properties additions to handle different quirks
- A bunch of fixes for smartphone IOP related issues

For ST Microelectronics' ST21NFCA and ST21NFCB drivers:

- ISO15693 support for st21nfcb
- checkpatch and sparse related warning fixes
- Code cleanups and a few minor fixes

Finally, Marvell added ISO15693 support to the NCI stack, together with a
couple of NCI fixes."

For the Bluetooth bits, Johan says:

"This 3.18 pull request replaces the one I did on Monday ("bluetooth-next
2014-09-22", which hasn't been pulled yet). The additions since the last
request are:

 - SCO connection fix for devices not supporting eSCO
 - Cleanups regarding the SCO establishment logic
 - Remove unnecessary return value from logging functions
 - Header compression fix for 6lowpan
 - Cleanups to the ieee802154/mrf24j40 driver

Here's a copy from previous request that this one replaces:

'
Here are some more patches for 3.18. They include various fixes to the
btusb HCI driver, a fix for LE SMP, as well as adding Jukka to the
MAINTAINERS file for generic 6LoWPAN (as requested by Alexander Aring).

I've held on to this pull request a bit since we were waiting for a SCO
related fix to get sorted out first. However, since the merge window is
getting closer I decided not to wait for it. If we do get the fix sorted
out there'll probably be a second small pull request later this week.
'"

And,

"Unless 3.17 gets delayed this will probably be our last -next pull request for
3.18. We've got:

  - New Marvell hardware supportr
  - Multicast support for 6lowpan
  - Several of 6lowpan fixes & cleanups
  - Fix for a (false-positive) lockdep warning in L2CAP
  - Minor btusb cleanup"

On top of all that comes the usual sort of updates to ath5k, ath9k,
ath10k, brcmfmac, mwifiex, and wil6210.  This time around there are
also a number of rtlwifi updates to enable some new hardware and
to reconcile the in-kernel drivers with some newer releases of the
Realtek vendor drivers.  Also of note is some device tree work for
the bcma bus.

Please let me know if there are problems!

5a17dae422 efi: Add efi= parameter parsing to the EFI boot stub
We need a way to customize the behaviour of the EFI boot stub, in
particular, we need a way to disable the "chunking" workaround, used
when reading files from the EFI System Partition.

One of my machines doesn't cope well when reading files in 1MB chunks to
a buffer above the 4GB mark - it appears that the "chunking" bug
workaround triggers another firmware bug. This was only discovered with
commit 4bf7111f50 ("x86/efi: Support initrd loaded above 4G"), and
that commit is perfectly valid. The symptom I observed was a corrupt
initrd rather than any kind of crash.

efi= is now used to specify EFI parameters in two very different
execution environments, the EFI boot stub and during kernel boot.

There is also a slight performance optimization by enabling efi=nochunk,
but that's offset by the fact that you're more likely to run into
firmware issues, at least on x86. This is the rationale behind leaving
the workaround enabled by default.

Also provide some documentation for EFI_READ_CHUNK_SIZE and why we're
using the current value of 1MB.

The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.

Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.

Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

2374a5399b i2c: exynos: add support for HSI2C module on Exynos7
The HSI2C module on Exynos7 differs in the transfer status
bits. Transfer status bits were moved to INT_ENABLE and
INT_STATUS registers

This patch adds support for the HSI2C module on Exynos7.
1. Implementes a "hw" field in the variant struct to distinguish
   the hardware.
2. Updates the dt-new compatible in dt-binding documenation

f3354ab674 ARM: 8169/1: l2c: parse cache properties from ePAPR definitions
When both 'cache-size' and 'cache-sets' are specified for a L2 cache
controller node, parse those properties and set up the
set size based on which type of L2 cache controller we are using.

Update the L2 cache controller Device Tree binding with the optional
'cache-size', 'cache-sets', 'cache-block-size' and 'cache-line-size'
properties. These come from the ePAPR specification.

Using the cache size, number of sets and cache line size we can
calculate desired associativity of the L2 cache. This is done
by the calculation:

    set size = cache size / sets
    ways = set size / line size
    way size = cache size / ways = sets * line size
    associativity = cache size / way size

Example output from the PB1176 DT that look like this:

L2: l2-cache {
    compatible = "arm,l220-cache";
    (...)
    arm,override-auxreg;
    cache-size = <131072>; // 128kB
    cache-sets = <512>;
    cache-line-size = <32>;
};

Ends up like this:

L2C OF: override cache size: 131072 bytes (128KB)
L2C OF: override line size: 32 bytes
L2C OF: override way size: 16384 bytes (16KB)
L2C OF: override associativity: 8
L2C: DT/platform modifies aux control register: 0x02020fff -> 0x02030fff
L2C-220 cache controller enabled, 8 ways, 128 kB
L2C-220: CACHE_ID 0x41000486, AUX_CTRL 0x06030fff

Which is consistent with the value earlier hardcoded for the
PB1176 platform.

This patch is an extended version based on the initial patch
by Florian Fainelli.

df59fa7f4b spi: orion: support armada extended baud rates
The Armada SoC family implementation of this SPI hardware module has
extended the configuration register to allow for a wider range of SPI
clock rates. Specifically the Serial Baud Rate Pre-selection bits in the
SPI Interface Configuration Register now also use bits 6 and 7 as well.

Modify the baud rate calculation to handle these differences for the
Armada case. Potentially a baud rate can be setup using a number of
different pre-scalar and scalar combinations. This code tries all
possible pre-scalar divisors (8 in total) to try and find the most
accurate set.

This change introduces (and documents) a new device tree compatible
device name "armada-370-spi" to support this.

Add "msi_bus" support for endpoints, so an administrator can prevent the
use of MSI and MSI-X for individual devices.

Note that as for bridges, these changes only affect future driver requests
for MSI or MSI-X, so drivers may need to be reloaded.

e3118e8359 net: tcp: add DCTCP congestion control algorithm
This work adds the DataCenter TCP (DCTCP) congestion control
algorithm [1], which has been first published at SIGCOMM 2010 [2],
resp. follow-up analysis at SIGMETRICS 2011 [3] (and also, more
recently as an informational IETF draft available at [4]).

DCTCP is an enhancement to the TCP congestion control algorithm for
data center networks. Typical data center workloads are i.e.
i) partition/aggregate (queries; bursty, delay sensitive), ii) short
messages e.g. 50KB-1MB (for coordination and control state; delay
sensitive), and iii) large flows e.g. 1MB-100MB (data update;
throughput sensitive). DCTCP has therefore been designed for such
environments to provide/achieve the following three requirements:

  * High burst tolerance (incast due to partition/aggregate)
  * Low latency (short flows, queries)
  * High throughput (continuous data updates, large file
    transfers) with commodity, shallow buffered switches

The basic idea of its design consists of two fundamentals: i) on the
switch side, packets are being marked when its internal queue
length > threshold K (K is chosen so that a large enough headroom
for marked traffic is still available in the switch queue); ii) the
sender/host side maintains a moving average of the fraction of marked
packets, so each RTT, F is being updated as follows:

 F := X / Y, where X is # of marked ACKs, Y is total # of ACKs
 alpha := (1 - g) * alpha + g * F, where g is a smoothing constant

The resulting alpha (iow: probability that switch queue is congested)
is then being used in order to adaptively decrease the congestion
window W:

 W := (1 - (alpha / 2)) * W

The means for receiving marked packets resp. marking them on switch
side in DCTCP is the use of ECN.

RFC3168 describes a mechanism for using Explicit Congestion Notification
from the switch for early detection of congestion, rather than waiting
for segment loss to occur.

However, this method only detects the presence of congestion, not
the *extent*. In the presence of mild congestion, it reduces the TCP
congestion window too aggressively and unnecessarily affects the
throughput of long flows [4].

DCTCP, as mentioned, enhances Explicit Congestion Notification (ECN)
processing to estimate the fraction of bytes that encounter congestion,
rather than simply detecting that some congestion has occurred. DCTCP
then scales the TCP congestion window based on this estimate [4],
thus it can derive multibit feedback from the information present in
the single-bit sequence of marks in its control law. And thus act in
*proportion* to the extent of congestion, not its *presence*.

Switches therefore set the Congestion Experienced (CE) codepoint in
packets when internal queue lengths exceed threshold K. Resulting,
DCTCP delivers the same or better throughput than normal TCP, while
using 90% less buffer space.

It was found in [2] that DCTCP enables the applications to handle 10x
the current background traffic, without impacting foreground traffic.
Moreover, a 10x increase in foreground traffic did not cause any
timeouts, and thus largely eliminates TCP incast collapse problems.

The algorithm itself has already seen deployments in large production
data centers since then.

We did a long-term stress-test and analysis in a data center, short
summary of our TCP incast tests with iperf compared to cubic:

This test measured DCTCP throughput and latency and compared it with
CUBIC throughput and latency for an incast scenario. In this test, 19
senders sent at maximum rate to a single receiver. The receiver simply
ran iperf -s.

The senders ran iperf -c <receiver> -t 30. All senders started
simultaneously (using local clocks synchronized by ntp).

This test was repeated multiple times. Below shows the results from a
single test. Other tests are similar. (DCTCP results were extremely
consistent, CUBIC results show some variance induced by the TCP timeouts
that CUBIC encountered.)

For this test, we report statistics on the number of TCP timeouts,
flow throughput, and traffic latency.

1) Timeouts (total over all flows, and per flow summaries):

            CUBIC            DCTCP
  Total     3227             25
  Mean       169.842          1.316
  Median     183              1
  Max        207              5
  Min        123              0
  Stddev      28.991          1.600

Timeout data is taken by measuring the net change in netstat -s
"other TCP timeouts" reported. As a result, the timeout measurements
above are not restricted to the test traffic, and we believe that it
is likely that all of the "DCTCP timeouts" are actually timeouts for
non-test traffic. We report them nevertheless. CUBIC will also include
some non-test timeouts, but they are drawfed by bona fide test traffic
timeouts for CUBIC. Clearly DCTCP does an excellent job of preventing
TCP timeouts. DCTCP reduces timeouts by at least two orders of
magnitude and may well have eliminated them in this scenario.

2) Throughput (per flow in Mbps):

            CUBIC            DCTCP
  Mean      521.684          521.895
  Median    464              523
  Max       776              527
  Min       403              519
  Stddev    105.891            2.601
  Fairness    0.962            0.999

Throughput data was simply the average throughput for each flow
reported by iperf. By avoiding TCP timeouts, DCTCP is able to
achieve much better per-flow results. In CUBIC, many flows
experience TCP timeouts which makes flow throughput unpredictable and
unfair. DCTCP, on the other hand, provides very clean predictable
throughput without incurring TCP timeouts. Thus, the standard deviation
of CUBIC throughput is dramatically higher than the standard deviation
of DCTCP throughput.

Mean throughput is nearly identical because even though cubic flows
suffer TCP timeouts, other flows will step in and fill the unused
bandwidth. Note that this test is something of a best case scenario
for incast under CUBIC: it allows other flows to fill in for flows
experiencing a timeout. Under situations where the receiver is issuing
requests and then waiting for all flows to complete, flows cannot fill
in for timed out flows and throughput will drop dramatically.

3) Latency (in ms):

            CUBIC            DCTCP
  Mean      4.0088           0.04219
  Median    4.055            0.0395
  Max       4.2              0.085
  Min       3.32             0.028
  Stddev    0.1666           0.01064

Latency for each protocol was computed by running "ping -i 0.2
<receiver>" from a single sender to the receiver during the incast
test. For DCTCP, "ping -Q 0x6 -i 0.2 <receiver>" was used to ensure
that traffic traversed the DCTCP queue and was not dropped when the
queue size was greater than the marking threshold. The summary
statistics above are over all ping metrics measured between the single
sender, receiver pair.

The latency results for this test show a dramatic difference between
CUBIC and DCTCP. CUBIC intentionally overflows the switch buffer
which incurs the maximum queue latency (more buffer memory will lead
to high latency.) DCTCP, on the other hand, deliberately attempts to
keep queue occupancy low. The result is a two orders of magnitude
reduction of latency with DCTCP - even with a switch with relatively
little RAM. Switches with larger amounts of RAM will incur increasing
amounts of latency for CUBIC, but not for DCTCP.

4) Convergence and stability test:

This test measured the time that DCTCP took to fairly redistribute
bandwidth when a new flow commences. It also measured DCTCP's ability
to remain stable at a fair bandwidth distribution. DCTCP is compared
with CUBIC for this test.

At the commencement of this test, a single flow is sending at maximum
rate (near 10 Gbps) to a single receiver. One second after that first
flow commences, a new flow from a distinct server begins sending to
the same receiver as the first flow. After the second flow has sent
data for 10 seconds, the second flow is terminated. The first flow
sends for an additional second. Ideally, the bandwidth would be evenly
shared as soon as the second flow starts, and recover as soon as it
stops.

The results of this test are shown below. Note that the flow bandwidth
for the two flows was measured near the same time, but not
simultaneously.

DCTCP performs nearly perfectly within the measurement limitations
of this test: bandwidth is quickly distributed fairly between the two
flows, remains stable throughout the duration of the test, and
recovers quickly. CUBIC, in contrast, is slow to divide the bandwidth
fairly, and has trouble remaining stable.

SYN/ACK ECT test:

This test demonstrates the importance of ECT on SYN and SYN-ACK packets
by measuring the connection probability in the presence of competing
flows for a DCTCP connection attempt *without* ECT in the SYN packet.
The test was repeated five times for each number of competing flows.

              Competing Flows  1 |    2 |    4 |    8 |   16
                               ------------------------------
Mean Connection Probability    1 | 0.67 | 0.45 | 0.28 |    0
Median Connection Probability  1 | 0.65 | 0.45 | 0.25 |    0

As the number of competing flows moves beyond 1, the connection
probability drops rapidly.

Enabling DCTCP with this patch requires the following steps:

DCTCP must be running both on the sender and receiver side in your
data center, i.e.:

  sysctl -w net.ipv4.tcp_congestion_control=dctcp

Also, ECN functionality must be enabled on all switches in your
data center for DCTCP to work. The default ECN marking threshold (K)
heuristic on the switch for DCTCP is e.g., 20 packets (30KB) at
1Gbps, and 65 packets (~100KB) at 10Gbps (K > 1/7 * C * RTT, [4]).

In above tests, for each switch port, traffic was segregated into two
queues. For any packet with a DSCP of 0x01 - or equivalently a TOS of
0x04 - the packet was placed into the DCTCP queue. All other packets
were placed into the default drop-tail queue. For the DCTCP queue,
RED/ECN marking was enabled, here, with a marking threshold of 75 KB.
More details however, we refer you to the paper [2] under section 3).

There are no code changes required to applications running in user
space. DCTCP has been implemented in full *isolation* of the rest of
the TCP code as its own congestion control module, so that it can run
without a need to expose code to the core of the TCP stack, and thus
nothing changes for non-DCTCP users.

Changes in the CA framework code are minimal, and DCTCP algorithm
operates on mechanisms that are already available in most Silicon.
The gain (dctcp_shift_g) is currently a fixed constant (1/16) from
the paper, but we leave the option that it can be chosen carefully
to a different value by the user.

In case DCTCP is being used and ECN support on peer site is off,
DCTCP falls back after 3WHS to operate in normal TCP Reno mode.

Pull cgroup fixes from Tejun Heo:
 "This is quite late but these need to be backported anyway.

  This is the fix for a long-standing cpuset bug which existed from
  2009.  cpuset makes use of PF_SPREAD_{PAGE|SLAB} flags to modify the
  task's memory allocation behavior according to the settings of the
  cpuset it belongs to; unfortunately, when those flags have to be
  changed, cpuset did so directly even whlie the target task is running,
  which is obviously racy as task->flags may be modified by the task
  itself at any time.  This obscure bug manifested as corrupt
  PF_USED_MATH flag leading to a weird crash.

  The bug is fixed by moving the flag to task->atomic_flags.  The first
  two are prepatory ones to help defining atomic_flags accessors and the
  third one is the actual fix"

8369289864 ARM: SoC fixes for 3.17
Here's our last set of fixes for 3.17. Most of these are for TI platforms,
 fixing some noisy Kconfig issues, runtime clock and power issues on
 several platforms and NAND timings on DRA7.
 
 There are also a couple of bug fixes for i.MX, one for QCOM and a small
 fix to avoid section mismatch noise on PXA.
 
 Diffstat looks large, partially due to some tables being updated and
 thus touching many lines. The qcom gsbi change also restructures clock
 management a bit and thus touches a bunch of lines.
 
 All in all, a bit more changes than we'd like at this point, but nothing
 stands out as risky either so it seems like the right thing to send it
 up now instead of holding it to the merge window.

180b2f95dd block: Replace bi_integrity with bi_special
For commands like REQ_COPY we need a way to pass extra information along
with each bio. Like integrity metadata this information must be
available at the bottom of the stack so bi_private does not suffice.

Rename the existing bi_integrity field to bi_special and make it a union
so we can have different bio extensions for each class of command.

We previously used bi_integrity != NULL as a way to identify whether a
bio had integrity metadata or not. Introduce a REQ_INTEGRITY to be the
indicator now that bi_special can contain different things.

In addition, bio_integrity(bio) will now return a pointer to the
integrity payload (when applicable).

37e1041f04 clk: sunxi: mod0: Introduce MMC proper phase handling
The MMC clock we thought we had until now are actually not one but three
different clocks.

The main one is unchanged, and will have three outputs:
  - The clock fed into the MMC
  - a sample and output clocks, to deal with when should we output/sample data
    to/from the MMC bus

The phase control we had are actually controlling the two latter clocks, but
the main MMC one is unchanged.

We can adjust the phase with a 3 bits value, from 0 to 7, 0 meaning a 180 phase
shift, and the other values being the number of periods from the MMC parent
clock to outphase the clock of.

99c55f7d47 bpf: introduce BPF syscall and maps
BPF syscall is a multiplexor for a range of different operations on eBPF.
This patch introduces syscall with single command to create a map.
Next patch adds commands to access maps.

'maps' is a generic storage of different types for sharing data between kernel
and userspace.

Userspace example:
/* this syscall wrapper creates a map with given type and attributes
 * and returns map_fd on success.
 * use close(map_fd) to delete the map
 */
int bpf_create_map(enum bpf_map_type map_type, int key_size,
                   int value_size, int max_entries)
{
    union bpf_attr attr = {
        .map_type = map_type,
        .key_size = key_size,
        .value_size = value_size,
        .max_entries = max_entries
    };

    return bpf(BPF_MAP_CREATE, &attr, sizeof(attr));
}

'union bpf_attr' is backwards compatible with future extensions.

dd42a0882a Docs: this_cpu_ops: remove redundant add forms
Commit ac490f4dca (Documentation: this_cpu_ops.txt: Update description
of this_cpu_ops) added lists of {__,}this_cpu operations, but these have
duplicate, parameter-less entries for {__,}this_cpu_add which don't
correspond to any implementation. No other operations have such
duplicate entries.

Given both are also listed with their full complement of arguments, the
empty forms are redundant and can be removed. This patch performs said
removal.

19f94f9700 v4l2-pci-skeleton: Only build if PCI is available
Currently arm64 does not support PCI but it does support v4l2. Since the
PCI skeleton driver is built unconditionally as a module with no dependency
on PCI this causes build failures for arm64 allmodconfig. Fix this by
defining a symbol VIDEO_PCI_SKELETON for the skeleton and conditionalising
the build on that.

6ab3430129 mfd: Add ACPI support
If an MFD device is backed by ACPI namespace, we should allow subdevice
drivers to access their corresponding ACPI companion devices through normal
means (e.g using ACPI_COMPANION()).

This patch adds such support to the MFD core. If the MFD parent device
does not specify any ACPI _HID/_CID for the child device, the child
device will share the parent ACPI companion device. Otherwise the child
device will be assigned with the corresponding ACPI companion, if found
in the namespace below the parent.

662a958638 PM / AVS: rockchip-io: add driver handling Rockchip io domains
IO domain voltages on some Rockchip SoCs are variable but need to be
kept in sync between the regulators and the SoC using a special
register.

A specific example using rk3288:
- If the regulator hooked up to a pin like SDMMC0_VDD is 3.3V then
  bit 7 of GRF_IO_VSEL needs to be 0.  If the regulator hooked up to
  that same pin is 1.8V then bit 7 of GRF_IO_VSEL needs to be 1.

Said another way, this driver simply handles keeping bits in the SoC's
general register file (GRF) in sync with the actual value of a voltage
hooked up to the pins.

Note that this driver specifically doesn't include:
- any logic for deciding what voltage we should set regulators to
- any logic for deciding whether regulators (or internal SoC blocks)
  should have power or not have power

If there were some other software that had the smarts of making
decisions about regulators, it would work in conjunction with this
driver.  When that other software adjusted a regulator's voltage then
this driver would handle telling the SoC about it.  A good example is
vqmmc for SD.  In that case the dw_mmc driver simply is told about a
regulator.  It changes the regulator between 3.3V and 1.8V at the
right time.  This driver notices the change and makes sure that the
SoC is on the same page.

2ad654bc5e cpuset: PF_SPREAD_PAGE and PF_SPREAD_SLAB should be atomic flags
When we change cpuset.memory_spread_{page,slab}, cpuset will flip
PF_SPREAD_{PAGE,SLAB} bit of tsk->flags for each task in that cpuset.
This should be done using atomic bitops, but currently we don't,
which is broken.

Tetsuo reported a hard-to-reproduce kernel crash on RHEL6, which happened
when one thread tried to clear PF_USED_MATH while at the same time another
thread tried to flip PF_SPREAD_PAGE/PF_SPREAD_SLAB. They both operate on
the same task.

Here's the full report:
https://lkml.org/lkml/2014/9/19/230

To fix this, we make PF_SPREAD_PAGE and PF_SPREAD_SLAB atomic flags.

v4:
- updated mm/slab.c. (Fengguang Wu)
- updated Documentation.

8172296d87 Documentation: dt: soc: add Keystone Navigator DMA bindings
The Keystone Navigator DMA driver sets up the dma channels and flows for
the QMSS(Queue Manager SubSystem) who triggers the actual data movements
across clients using destination queues. Every client modules like
NETCP(Network Coprocessor), SRIO(Serial Rapid IO) and CRYPTO
Engines has its own instance of packet dma hardware. QMSS has also
an internal packet DMA module which is used as an infrastructure
DMA with zero copy.

Initially this driver was proposed as DMA engine driver but since the
hardware is not typical DMA engine and hence doesn't comply with typical
DMA engine driver needs, that approach was naked. Link to that
discussion -
	https://lkml.org/lkml/2014/3/18/340

As aligned, now we pair the Navigator DMA with its companion Navigator
QMSS subsystem driver.

a4dfb8c410 Documentation: dt: soc: add Keystone Navigator QMSS bindings
The QMSS (Queue Manager Sub System) found on Keystone SOCs is one of
the main hardware sub system which forms the backbone of the Keystone
Multi-core Navigator. QMSS consist of queue managers, packed-data structure
processors(PDSP), linking RAM, descriptor pools and infrastructure
Packet DMA.

The Queue Manager is a hardware module that is responsible for accelerating
management of the packet queues. Packets are queued/de-queued by writing or
reading descriptor address to a particular memory mapped location. The PDSPs
perform QMSS related functions like accumulation, QoS, or event management.
Linking RAM registers are used to link the descriptors which are stored in
descriptor RAM. Descriptor RAM is configurable as internal or external memory.

a5ec598650 phy: exynos-dp-video: Use syscon support to control pmu register
Currently the DP_PHY_ENABLE register is mapped in the driver,
and accessed to control power to the PHY.
With mfd-syscon and regmap interface available at our disposal,
it's wise to use that instead of using a 'reg' property for the
controller and allocating a memory resource for that.

To facilitate this, we have added another compatible string
for Exynso5420 SoC to acquire driver data which contains
different DP-PHY-CONTROL register offset.

1233f59f74 phy: Renesas R-Car Gen2 PHY driver
This PHY, though formally being a part of Renesas USBHS controller, contains the
UGCTRL2 register that controls multiplexing of the USB ports (Renesas calls them
channels) to the different USB controllers: channel 0 can be connected to either
PCI EHCI/OHCI or USBHS controllers, channel 2 can be connected to PCI EHCI/OHCI
or xHCI controllers.

This is a new driver for this USB PHY currently already supported under drivers/
usb/phy/. The reason for writing the new driver was the requirement that the
multiplexing  of USB channels to the controller be dynamic, depending on what
USB drivers  are loaded,  rather than static as provided by the old driver. The
infrastructure provided by drivers/phy/phy-core.c  seems to fit that purpose
ideally. The new driver only  supports device tree probing  for now.

The existing UWB documentation states that UWB devices show up in
/sys/class/uwb and /sys/bus/uwb/devices.  Up until the most recent
changes to add uwb devices to their own bus, neither of these statements
were actually true.  Now, UWB devices do show up in /sys/bus/uwb/devices
so the documentation has been updated to reflect that and removed
references to /sys/class/uwb.

The existing documentation also states that local UWB radio controller
(RC) devices also show up as UWB devices along with their wireless peer
UWB devices under /sys/class/uwb.  This is not true so that statement
has been removed.

734016b00b uas: Add no-report-opcodes quirk
Besides the ASM1051 (*) needing sdev->no_report_opcodes = 1, it turns out that
the JMicron JMS567 also needs it to work properly with uas (usb-storage always
sets it). Since some of the scsi devs were not to keen on the idea to
outrightly set sdev->no_report_opcodes = 1 for all uas devices, so add a quirk
for this, and set it for the JMS567.

*) Which has become a non-issue since we've completely blacklisted uas on
the ASM1051 for other reasons

4cdf507d54 icmp: add a global rate limitation
Current ICMP rate limiting uses inetpeer cache, which is an RBL tree
protected by a lock, meaning that hosts can be stuck hard if all cpus
want to check ICMP limits.

When say a DNS or NTP server process is restarted, inetpeer tree grows
quick and machine comes to its knees.

iptables can not help because the bottleneck happens before ICMP
messages are even cooked and sent.

This patch adds a new global limitation, using a token bucket filter,
controlled by two new sysctl :

icmp_msgs_per_sec - INTEGER
    Limit maximal number of ICMP packets sent per second from this host.
    Only messages whose type matches icmp_ratemask are
    controlled by this limit.
    Default: 1000

icmp_msgs_burst - INTEGER
    icmp_msgs_per_sec controls number of ICMP packets sent per second,
    while icmp_msgs_burst controls the burst size of these packets.
    Default: 50

Note that if we really want to send millions of ICMP messages per
second, we might extend idea and infra added in commit 04ca6973f7
("ip: make IP identifiers less predictable") :
add a token bucket in the ip_idents hash and no longer rely on inetpeer.

98f75b8291 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:

 1) If the user gives us a msg_namelen of 0, don't try to interpret
    anything pointed to by msg_name.  From Ani Sinha.

 2) Fix some bnx2i/bnx2fc randconfig compilation errors.

    The gist of the issue is that we firstly have drivers that span both
    SCSI and networking.  And at the top of that chain of dependencies
    we have things like SCSI_FC_ATTRS and SCSI_NETLINK which are
    selected.

    But since select is a sledgehammer and ignores dependencies,
    everything to select's SCSI_FC_ATTRS and/or SCSI_NETLINK has to also
    explicitly select their dependencies and so on and so forth.

    Generally speaking 'select' is supposed to only be used for child
    nodes, those which have no dependencies of their own.  And this
    whole chain of dependencies in the scsi layer violates that rather
    strongly.

    So just make SCSI_NETLINK depend upon it's dependencies, and so on
    and so forth for the things selecting it (either directly or
    indirectly).

    From Anish Bhatt and Randy Dunlap.

 3) Fix generation of blackhole routes in IPSEC, from Steffen Klassert.

 4) Actually notice netdev feature changes in rtl_open() code, from
    Hayes Wang.

 5) Fix divide by zero in bond enslaving, from Nikolay Aleksandrov.

 6) Missing memory barrier in sunvnet driver, from David Stevens.

 7) Don't leave anycast addresses around when ipv6 interface is
    destroyed, from Sabrina Dubroca.

 8) Don't call efx_{arch}_filter_sync_rx_mode before addr_list_lock is
    initialized in SFC driver, from Edward Cree.

 9) Fix missing DMA error checking in 3c59x, from Neal Horman.

10) Openvswitch doesn't emit OVS_FLOW_CMD_NEW notifications accidently,
    fix from Samuel Gauthier.

11) pch_gbe needs to select NET_PTP_CLASSIFY otherwise we can get a
    build error.

12) Fix macvlan regression wherein we stopped emitting
    broadcast/multicast frames over software devices.  From Nicolas
    Dichtel.

13) Fix infiniband bug due to unintended overflow of skb->cb[], from
    Eric Dumazet.  And add an assertion so this doesn't happen again.

14) dm9000_parse_dt() should return error pointers, not NULL.  From
    Tobias Klauser.

15) IP tunneling code uses this_cpu_ptr() in preemptible contexts, fix
    from Eric Dumazet.

c08860ffe5 hwmon: (ntc_thermistor) Add ntc thermistor to thermal subsystem as a sensor.
To get more comprehensive and integrated thermal management, it adds ntc
thermistor to thermal framework as a thermal sensor. It's governed thermal
susbsystem only if it is described in DT node. Otherwise, it just notifies
temperature to userspace via sysfs as it used to be.

This patch adds temperature monitoring support for F15h M60h processor.
 - Add new pci device id for the relevant processor
 - The functionality of REG_REPORTED_TEMPERATURE is moved to
   D0F0xBC_xD820_0CA4 [Reported Temperature Control]
   - So, use this to get CUR_TEMP value
   - Since we need an indirect register access, protect this with
     a mutex lock
 - Add Kconfig, Doc entries to indicate support for this processor.

e5bffb59cf mtd: physmap_of: Add non-obsolete map_rom probe
Previously, the only way to map a NOR device as a simple ROM was to
use the obsolete "direct-mapped" compatible binding (which further
requires device_type = "nor" and probe-type = "NOR" properties).

This patch adds an "mtd-rom" compatible binding to the "map_rom"
probe type.

a4a8c2c496 ARM: exynos: Move to generic PM domain DT bindings
This patch moves Exynos PM domain code to use the new generic PM domain
look-up framework introduced in previous patches, thus also allowing
the new code to be compiled with CONFIG_ARCH_EXYNOS.

This patch was originally submitted by Tomasz Figa when he was employed
by Samsung.

aa42240ab2 PM / Domains: Add generic OF-based PM domain look-up
This patch introduces generic code to perform PM domain look-up using
device tree and automatically bind devices to their PM domains.

Generic device tree bindings are introduced to specify PM domains of
devices in their device tree nodes.

Backwards compatibility with legacy Samsung-specific PM domain bindings
is provided, but for now the new code is not compiled when
CONFIG_ARCH_EXYNOS is selected to avoid collision with legacy code.
This will change as soon as the Exynos PM domain code gets converted to
use the generic framework in further patch.

This patch was originally submitted by Tomasz Figa when he was employed
by Samsung.

   parts.
 * bma180 - add BMA250 (note different from the BMA250E support above despite
   the naming).  A lot of driver reworking lead up to this - described below.
 
 New features
 * kxcjk1013 - add threshold event support.
 * rockchip - document DT bindings.
 * isl29018 - ACPI support
 * bma180 - enable use without IRQ
 
 Cleanups
 * Tree wide - drop owner field assignment if using the module_platform_driver
   helper as that assigns it anyway.
 * kxcjk1013 - drop a redundant assignment of the current range and fix a
   a defined but not used warning.
 * inv_mpu6050 - Remove an unnecessary cast form a void pointer.
 * rockchip - drop and unused variable.
 * at91_adc - make a local function static.
 * st-sensors-core - correctly handle an error in setting in
   st_sensors_set_drdy_int_pin
 * isl29018 - typo fix
 * bmc150 - fix incorrect scale value for 16G range (Driver new this cycle)
 * bmc150 - fix issues when CONFIG_PM_RUNTIME not set (Driver new this cycle)
 * ad7606 - line length tidy up.
 * bmg160 - set power state only if PM_RUNTIME is defined.
 * ak8975 - fix some unnecessary casting between char * and const char *
 * bma180 - prefix remaining bits and bobs with bma180_ and ensure consistent.
          - use a bool instead of an int for state (as its either on or off).
          - expose the temperature channel
          - statically allocate buffers to avoid need for update_scan_mode
            callback.
          - refactor to allow futher chip variants including support for part
            specific config and disable code + different resolutions.

Quite big pull request this time. Audio and UVC gadgets
 can now be used with our configfs-based binding. We have
 three PHY drivers being removed because a new one has been
 added using new PHY framework.
 
 Gadget framework got a new ->reset callback preparing for
 some other changes to come on next merge window.
 
 A few new drivers came in as well; among those we have a
 new UDC driver from Xilinx and two new glue layers for
 DWC3 (ST and Qualcomm).
 
 DWC3 also learned about tracepoints which will help debugging
 quite a bit.
 
 Other than that, a big series of non-critical fixes and
 cleanups.
 
 All patches have been on linux-next for quite a bit of time
 and I boot tested these changes on platforms I have access
 to and work with mainline.

b680c37a4d drm/i915: DocBook integration for frontbuffer tracking
I shouldn't ask everyone to do this and fail myself ...

This extracts all the frontbuffer tracking functions into
intel_frontbuffer.c, adds a DOC overview section and also adds the
missing kerneldoc for i915_gem_track_fb and also pulls it into the
same section for convenience.

v2: Don't forget about the header files.

v3: Oops, might check compilation next time around. To make my life
easier drop the increase_pllclock from set_base_atomic since really,
it doesn't matter if you see your Oops or kgdb with a tiny bit of lag.

This patch introduces the driver for the RTC in the Allwinner A31 and
A23 SoCs.

Unlike the RTC found in A10/A20 SoCs, which was part of the timer, the
RTC in A31/A23 are a separate hardware block, which also contain a few
controls for the RTC block hardware (a regulator and RTC block GPIO pin
latches), while also having separate interrupts for the alarms.

The hardware is different enough to make a different driver for it.

static iotable map. Now that we use gen_pool to manage sram, we can
completely remove all of these static mappings and use gen_pool_alloc()
to get the one page of sram space needed to implement errata I688.
omap_bus_sync will be NOP until SRAM initialization happens.

beneficial to be able to run the system in a logging only mode,

2134cb997f gpio: syscon: reuse for keystone 2 socs
On Keystone SOCs, ARM host can send interrupts to DSP cores using the
DSP GPIO controller IP. Each DSP GPIO controller provides 28 IRQ signals for
each DSP core. This is one of the component used by the IPC mechanism used
on Keystone SOCs.

Keystone 2 DSP GPIO controller has specific features:
- each GPIO can be configured only as output pin;
- setting GPIO value to 1 causes IRQ generation on target DSP core;
- reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still
  pending.

This patch updates gpio-syscon driver to be reused by Keystone 2 SoCs,
because the Keystone 2 DSP GPIO controller is controlled through Syscon
devices and, as requested by Linus Walleij, such kind of GPIO controllers
should be integrated with drivers/gpio/gpio-syscon.c driver.

Most of it is based on what we already have for writers. This allows
readers to be very independent (and thus configurable), enabling
future module parameters to control things such as rw distribution.
Furthermore, readers have their own delaying function, allowing us
to test different rw critical region latencies, and stress locking
internals. Similarly, statistics, for now will only serve for the
number of lock acquisitions -- as opposed to writers, readers have
no failure detection.

In addition, introduce a new nreaders_stress module parameter. The
default number of readers will be the same number of writers threads.
Writer threads are interleaved with readers. Documentation is updated,
respectively.

writes compared to non blocking locks, if run long enough it can have
the same torturous effect. Furthermore it is more representative of
mutex hold times and can stress better things like thrashing.

c1ce1b02bb f2fs: give an option to enable in-place-updates during fsync to users
If user wrote F2FS_IPU_FSYNC:4 in /sys/fs/f2fs/ipu_policy, f2fs_sync_file
only starts to try in-place-updates.
And, if the number of dirty pages is over /sys/fs/f2fs/min_fsync_blocks, it
keeps out-of-order manner. Otherwise, it triggers in-place-updates.

This may be used by storage showing very high random write performance.

For example, it can be used when,

Seq. writes (Data) + wait + Seq. writes (Node)

is pretty much slower than,

Rand. writes (Data)

  arm64: add PSCI CPU_SUSPEND based cpu_suspend support

  arm64: kernel: refactor the CPU suspend API for retention states

2014-09-12 10:50:21 +01:00
Lorenzo Pieralisi
3f8161b260 Documentation: arm: define DT idle states bindings
ARM based platforms implement a variety of power management schemes that
allow processors to enter idle states at run-time.
The parameters defining these idle states vary on a per-platform basis forcing
the OS to hardcode the state parameters in platform specific static tables
whose size grows as the number of platforms supported in the kernel increases
and hampers device drivers standardization.

Therefore, this patch aims at standardizing idle state device tree bindings
for ARM platforms. Bindings define idle state parameters inclusive of entry
methods and state latencies, to allow operating systems to retrieve the
configuration entries from the device tree and initialize the related power
management drivers, paving the way for common code in the kernel to deal with
idle states and removing the need for static data in current and previous
kernel versions.

ARM64 platforms require the DT to define an entry-method property
for idle states.

On system implementing PSCI as an enable-method to enter low-power
states the PSCI CPU suspend method requires the power_state parameter to
be passed to the PSCI CPU suspend function.

This parameter is specific to a power state and platform specific,
therefore must be provided by firmware to the OS in order to enable
proper call sequence.

Thus, this patch also adds a property in the PSCI bindings that
describes how the PSCI CPU suspend power_state parameter should be
defined in DT in all device nodes that rely on PSCI CPU suspend method usage.

edbaae5a5c Merge tag 'topic/vblank-rework-2014-09-12' of git://anongit.freedesktop.org/drm-intel into drm-next
So updated vblank-rework pull request, now with the polish that Mario
requested applied (and reviewed by him). Also with backmerge like you've
requested for easier merging.

The neat thing this finally allows is to immediately disable the vblank
interrupt on the last drm_vblank_put if the hardware has perfectly
accurate vblank counter and timestamp readout support. On i915 that
required piles of small adjustements from Ville since depending upon the
platform and port the vblank happens at different scanout lines.

Of course this is fully opt-in and per-device (we need that since gen2
doesn't have a hw vblank counter).

adff5962fd Input: introduce palmas-pwrbutton
Many palmas family of PMICs have support for interrupt based power button.
This allows the device to notify the processor of external push button
events over the shared palmas interrupt. However, this event is generated
only during a "press" operation. Software is supposed to poll(sigh!) for
detecting a release event.

The PMIC also supports ability to power off independent of the software
decisions when the button is pressed for a long duration if the PMIC is
appropriately configured on the platform.

Even though the function is similar to twl4030_pwrbutton, it is
substantially different in operation to belong to a new driver of it's own.

using LVDS channel 1 on an i.MX53 leads to following error:

imx-ldb 53fa8008.ldb: unable to set di0 parent clock to ldb_di1

This comes from imx_ldb_set_clock with mux = 0. Mux parameter must be "1" for
reparenting di1 clock to ldb_di1. The value of the mux param comes from device
tree port settings.

On i.MX5, the internal two-input-multiplexer is used. Due to hardware limitations,
only one port (port@[0,1]) can be used for each channel (lvds-channel@[0,1],
respectively)

fcd0864cdb clk: max77686: Improve Maxim 77686 PMIC clocks binding
Like most clock drivers, the Maxim 77686 PMIC clock binding
follows the convention that the "#clock-cells" property is
used to specify the number of cells in a clock provider.

But the binding document is not clear enough that it shall
be set to 1 since the PMIC support multiple clocks outputs.

Also, explain that the clocks identifiers are defined in a
header file that can be included by Device Tree source with
client nodes to avoid using magic numbers.

Finally, add "clock-output-names" as an optional property
since now is supported by the clock driver.

02ab695bb3 net: filter: add "load 64-bit immediate" eBPF instruction
add BPF_LD_IMM64 instruction to load 64-bit immediate value into a register.
All previous instructions were 8-byte. This is first 16-byte instruction.
Two consecutive 'struct bpf_insn' blocks are interpreted as single instruction:
insn[0].code = BPF_LD | BPF_DW | BPF_IMM
insn[0].dst_reg = destination register
insn[0].imm = lower 32-bit
insn[1].code = 0
insn[1].imm = upper 32-bit
All unused fields must be zero.

Classic BPF has similar instruction: BPF_LD | BPF_W | BPF_IMM
which loads 32-bit immediate value into a register.

x64 JITs it as single 'movabsq %rax, imm64'
arm64 may JIT as sequence of four 'movk x0, #imm16, lsl #shift' insn

Note that old eBPF programs are binary compatible with new interpreter.

It helps eBPF programs load 64-bit constant into a register with one
instruction instead of using two registers and 4 instructions:
BPF_MOV32_IMM(R1, imm32)
BPF_ALU64_IMM(BPF_LSH, R1, 32)
BPF_MOV32_IMM(R2, imm32)
BPF_ALU64_REG(BPF_OR, R1, R2)

User space generated programs will use this instruction to load constants only.

To tell kernel that user space needs a pointer the _pseudo_ variant of
this instruction may be added later, which will use extra bits of encoding
to indicate what type of pointer user space is asking kernel to provide.
For example 'off' or 'src_reg' fields can be used for such purpose.
src_reg = 1 could mean that user space is asking kernel to validate and
load in-kernel map pointer.
src_reg = 2 could mean that user space needs readonly data section pointer
src_reg = 3 could mean that user space needs a pointer to per-cpu local data
All such future pseudo instructions will not be carrying the actual pointer
as part of the instruction, but rather will be treated as a request to kernel
to provide one. The kernel will verify the request_for_a_pointer, then
will drop _pseudo_ marking and will store actual internal pointer inside
the instruction, so the end result is the interpreter and JITs never
see pseudo BPF_LD_IMM64 insns and only operate on generic BPF_LD_IMM64 that
loads 64-bit immediate into a register. User space never operates on direct
pointers and verifier can easily recognize request_for_pointer vs other
instructions.

3d705d14fe mmc: implement Driver Stage Register handling
Some eMMC and SD cards implement a DSR register that allows to tune
raise/fall times and drive strength of the CMD and DATA outputs.
The values to use depend on the card in use and the host.
It might be needed to reduce the drive strength to prevent voltage peaks
above the host's specification.

Implement a 'dsr' devicetree property that allows to specify the value
to set the DSR to. For non-dt setups the new members of mmc_host can be
set by board code.

This patch was initially authored by Sascha Hauer. It contains
improvements authored by Markus Niebel and Uwe Kleine-König.

ae38273524 tty: vt8500_serial: add support for UART in WM8880 chips
Newer WonderMedia chips introduced another flag in the UART line control
register, which controls whether RTS/CTS signalling should be handled in
the driver or by the hardware itself.

This patch ensures that the kernel can control RTS/CTS (including
disabling it altogether) by forcing this flag to software mode on affected
chips (only WM8880 so far).

Also remove the redundant copy of the binding doc, while we are here.

a6eec92ec0 Revert "serial: uart: add hw flow control support configuration"
This reverts commit 06aa82e498.
This commit purports to enable auto CTS flow control for the 8250
UART driver. However, the 8250 UART driver already supports auto
CTS flow control via UART_CAP_AFE and UART_CAP_EFR. Indeed, this
patch introduces another DT attribute for which an existing firmware
flag already exists ("auto-flow-control"). Furthermore, the use of
UPF_HARD_FLOW requires the UART driver to define .throttle and
.unthrottle methods, neither of which are defined for the 8250 UART
driver (which will result in a NULL ptr dereference). Finally, this patch
supposes to fix existing bugs in the serial core for auto CTS-enabled
hardware, but does not include the class of hardware for which these
bugs exist.

capability is not routinely tested.   This commit therefore adds a
cbflood capability in which kthreads repeatedly registers large numbers
of callbacks.  One such kthread is created for each four CPUs (rounding
up), and the test may be controlled by several cbflood_* kernel boot
parameters, which control the number of bursts per flood, the number
of callbacks per burst, the time between bursts, and the time between
floods.  The default values are large enough to exercise RCU's emergency
responses to callback flooding.

01fe3aaa3a clocksource: sh_cmt: Document SoC specific bindings
In general Renesas hardware is not documented to the extent
where the relationship between IP blocks on different SoCs can be assumed
although they may appear to operate the same way. Furthermore the
documentation typically does not specify a version for individual
IP blocks. For these reasons a convention of using the SoC name in place
of a version and providing SoC-specific compat strings has been adopted.

Although not universally liked this convention is used in the bindings for
a number of drivers for Renesas hardware. The purpose of this patch is to
update the Renesas R-Car Compare Match Timer (CMT) driver to follow this
convention.

---
* I plan to follow up with patches to use these new bindings in the
  dtsi files for the affected SoCs.

v2
* Reorder compat entries so more-specific entries and their fallbacks
  are grouped with the fallback entry coming last.
* Explicitly document fallback

v3
* Avoid circular dependency in documentation of fallback
  behaviour of renesas,cmt-48-gen2
* Use consistent case for SoC names in compat string descriptions

18a47e6d8a net-timestamp: fix allocation error in test
A buffer is incorrectly zeroed to the length of the pointer. If
cfg_payload_len < sizeof(void *) this can overwrites unrelated memory.
The buffer contents are never read, so no need to zero.

a9fe8e2994 ipv4: implement igmp_qrv sysctl to tune igmp robustness variable
As in IPv6 people might increase the igmp query robustness variable to
make sure unsolicited state change reports aren't lost on the network. Add
and document this new knob to igmp code.

RFCs allow tuning this parameter back to first IGMP RFC, so we also use
this setting for all counters, including source specific multicast.

Also take over sysctl value when upping the interface and don't reuse
the last one seen on the interface.

2f711939d2 ipv6: add sysctl_mld_qrv to configure query robustness variable
This patch adds a new sysctl_mld_qrv knob to configure the mldv1/v2 query
robustness variable. It specifies how many retransmit of unsolicited mld
retransmit should happen. Admins might want to tune this on lossy links.

Also reset mld state on interface down/up, so we pick up new sysctl
settings during interface up event.

IPv6 certification requests this knob to be available.

I didn't make this knob netns specific, as it is mostly a setting in a
physical environment and should be per host.

This allows to explicitly specify the covered bus numbers in the

PCIe host controller instance.

Previously the driver relied on the behavior of pci_scan_root_bus() to fill
in a range of 0x00-0xff if no valid range was found.  We fall back to the
same range if no valid DT entry was found to keep backwards compatibility,
but now do it explicitly.

implement PCI controller driver.  Also add necessary DT documentation and

03e9f0cac5 pinctrl: clean up after enable refactoring
commit 2243a87d90
"pinctrl: avoid duplicated calling enable_pinmux_setting for a pin"
removed the .disable callback from the struct pinmux_ops,
making the .enable() callback the only remaining callback.

However .enable() is a bad name as it seems to imply that a
muxing can also be disabled. Rename the callback to .set_mux()
and also take this opportunity to clean out any remaining
mentions of .disable() from the documentation.

00406e8772 powerpc: fsl_pci: Add forced PCI Agent enumeration
The following commit prevents the MPC8548E on the XPedite5200 PrPMC
module from enumerating its PCI/PCI-X bus:

    powerpc/fsl-pci: use 'Header Type' to identify PCIE mode

The previous patch prevents any Freescale PCI-X bridge from enumerating
the bus, if it is hardware strapped into Agent mode.

In PCI-X, the Host is responsible for driving the PCI-X initialization
pattern to devices on the bus, so that they know whether to operate in
conventional PCI or PCI-X mode as well as what the bus timing will be.
For a PCI-X PrPMC, the pattern is driven by the mezzanine carrier it is
installed onto. Therefore, PrPMCs are PCI-X Agents, but one per system
may still enumerate the bus.

This patch causes the device node of any PCI/PCI-X bridge strapped into
Agent mode to be checked for the fsl,pci-agent-force-enum property. If
the property is present in the node, the bridge will be allowed to
enumerate the bus.

ee3d1570b5 kvm: fix potentially corrupt mmio cache
vcpu exits and memslot mutations can run concurrently as long as the
vcpu does not aquire the slots mutex. Thus it is theoretically possible
for memslots to change underneath a vcpu that is handling an exit.

If we increment the memslot generation number again after
synchronize_srcu_expedited(), vcpus can safely cache memslot generation
without maintaining a single rcu_dereference through an entire vm exit.
And much of the x86/kvm code does not maintain a single rcu_dereference
of the current memslots during each exit.

We can prevent the following case:

   vcpu (CPU 0)                             | thread (CPU 1)
--------------------------------------------+--------------------------
1  vm exit                                  |
2  srcu_read_unlock(&kvm->srcu)             |
3  decide to cache something based on       |
     old memslots                           |
4                                           | change memslots
                                            | (increments generation)
5                                           | synchronize_srcu(&kvm->srcu);
6  retrieve generation # from new memslots  |
7  tag cache with new memslot generation    |
8  srcu_read_unlock(&kvm->srcu)             |
...                                         |
   <action based on cache occurs even       |
    though the caching decision was based   |
    on the old memslots>                    |
...                                         |
   <action *continues* to occur until next  |
    memslot generation change, which may    |
    be never>                               |
                                            |

By incrementing the generation after synchronizing with kvm->srcu readers,
we ensure that the generation retrieved in (6) will become invalid soon
after (8).

Keeping the existing increment is not strictly necessary, but we
do keep it and just move it for consistency from update_memslots to
install_new_memslots.  It invalidates old cached MMIOs immediately,
instead of having to wait for the end of synchronize_srcu_expedited,
which makes the code more clearly correct in case CPU 1 is preempted
right after synchronize_srcu() returns.

To avoid halving the generation space in SPTEs, always presume that the
low bit of the generation is zero when reconstructing a generation number
out of an SPTE.  This effectively disables MMIO caching in SPTEs during
the call to synchronize_srcu_expedited.  Using the low bit this way is
somewhat like a seqcount---where the protected thing is a cache, and
instead of retrying we can simply punt if we observe the low bit to be 1.

32797b3e06 video: fix composite video connector compatible string
The quite-recently-added analog-tv-connector bindings say that the
compatible string for composite video connector is
"composite-connector". That string is also used in the omap3-n900.dts
file. However, the connector driver uses "composite-video-connector", so
this has never worked.

While changing the driver's compatible string to "composite-connector"
would be safer, as published DT bindings should not be changed, I'd
rather fix the bindings in this case for two reasons:

* composite-connector is a bit too generic name, as it doesn't even hint
  at video.
* it's clear that this has never worked, which means no one has used
  those bindings, which should make it safe to change this.

a5325ae5b8 tipc: add name distributor resiliency queue
TIPC name table updates are distributed asynchronously in a cluster,
entailing a risk of certain race conditions. E.g., if two nodes
simultaneously issue conflicting (overlapping) publications, this may
not be detected until both publications have reached a third node, in
which case one of the publications will be silently dropped on that
node. Hence, we end up with an inconsistent name table.

In most cases this conflict is just a temporary race, e.g., one
node is issuing a publication under the assumption that a previous,
conflicting, publication has already been withdrawn by the other node.
However, because of the (rtt related) distributed update delay, this
may not yet hold true on all nodes. The symptom of this failure is a
syslog message: "tipc: Cannot publish {%u,%u,%u}, overlap error".

In this commit we add a resiliency queue at the receiving end of
the name table distributor. When insertion of an arriving publication
fails, we retain it in this queue for a short amount of time, assuming
that another update will arrive very soon and clear the conflict. If so
happens, we insert the publication, otherwise we drop it.

The (configurable) retention value defaults to 2000 ms. Knowing from
experience that the situation described above is extremely rare, there
is no risk that the queue will accumulate any large number of items.

eadb0019d2 ASoC: fsl-sai: using 'lsb-first' property instead of 'big-endian-data'.
The 'big-endian-data' property is originally used to indicate whether the
LSB firstly or MSB firstly will be transmitted to the CODEC or received
from the CODEC, and there has nothing relation to the memory data.

Generally, if the audio data in big endian format, which will be using the
bytes reversion, Here this can only be used to bits reversion.

So using the 'lsb-first' instead of 'big-endian-data' can make the code
to be readable easier and more easy to understand what this property is
used to do.

This property used for configuring whether the LSB or the MSB is transmitted
first for the fifo data.

 The rest is mostly:
 
 * A handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular)
 * Some MTD/NAND fixes for OMAP
 * Minor DT fixes for shmobile
 * Warning fix for UP builds on vexpress/spc
 
 There's also a couple of patches that wires up hwmod on TI's DRA7 SoC
 so it can boot. Drivers and the rest had landed for 3.17, and it's small
 and isolated so it made sense to pick up now even if it's not a bugfix.

5566401f2f stmmac: ptp: fix the reference clock
The PTP reference clock, used for setting the addend in the Timestamp Addend
Register, was erroneously hard-coded (as reported in the databook just as
example).

The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a
reference clock (clk_ptp_ref_i) that can be passed from the platform.

If not passed, the main driver clock will be used as default; note that
this can be fine on some platforms.

Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms,
as side effect, the ptp clock can move faster/slower than the system clock.

bd597f47ca devicetree: Dialog Semiconductor consolidate existing vendor prefixes to standardise on 'dlg'
This patch series updates the device tree vendor prefix for
Dialog Semiconductor.

Various methods are currently used throughout the kernel: 'diasemi',
'dialog' and 'dlg'. Others have also been suggested.

This patch set aims to consolidate the usage of the vendor prefix to
use a common standard. The prefix 'dlg' is used.

abdc08a3a2 gpio: change gpiochip_request_own_desc() prototype
The current prototype of gpiochip_request_own_desc() requires to obtain
a pointer to a descriptor. This is in contradiction to all other GPIO
request schemes, and imposes an extra step of obtaining a descriptor to
drivers. Most drivers actually cannot even perform that step since the
function that does it (gpichip_get_desc()) is gpiolib-private.

Change gpiochip_request_own_desc() to return a descriptor from a
(chip, hwnum) tuple and update users of this function (currently
gpiolib-acpi only).

a3e83f05fb ARM: OMAP2+: GPMC: Support Software ECC scheme via DT
For v3.14 and prior, 1-bit Hamming code ECC via software was the
default choice for some boards e.g. 3430sdp.
Commit ac65caf514 in v3.15 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.

This ECC layout change causes NAND filesystems created in v3.14
and prior to be unusable in v3.15 and later. So don't mark "sw" scheme
as deperecated and support it.

39bdc95871 1st round of new IIO drivers, functionality and cleanups for the 3.18 cycle.
Maintainer Updates
 
 * Add 3 designated reviewers for IIO.  Lars, Peter and Hartmut have been
   actively reviewing a lot of patches for a while now so this reflects
   the status quo.  These three are probably the only reason I keep
   my head above the water!
 
 New drivers and device support
 
 * max5821 DAC
 * Rockchip SARADC
 * TI ADC128S052 ADC
 * BMC150 Accelerometer
 * exynos ADC driver gains support for s3c24xx and s3c64xx parts.
 * kxcjk-1013 gainst range control and runtime PM support to drive
   down it's power usage.
 
 Driver removals
 
 * Drop ad5930, ad99850, ad9852, ad9910 and ad9951 drivers on the simple
   basis that they drivers just provided a register write function with
   no compliant user space ABI whatsoever.  Much better to drop them and
   start again for these in the fullness of time.
 
 Core Enhancements
 
 * Join together neighbouring elements in the demux units that feeds
   the binary interfaces.  This cuts down on the number of individual
   copies needed  when splitting out individual channels from the incoming
   channel scans.
 * Other demux related cleanups such as using roundup instead of a local
   implementation.
 
 Cleanups
 
 * Drop an unnecessary double setting of the owner field in xilinx adc.
 * Some more patches to use managed (devm) interfaces to cut down on
   complexity of removal code.
 * adis16060 coding style fixlets.
 * Fix some incorrect error returns in the Xilinx ADC driver.
 * Coding style fixlets for various accelerometer drivers.
 * Some sparse warning fixes to do with endianness and sign of variables.
 * Fix an incorrect and entirely pointless use of sizeof on a dynamic pointer
   in hid-sensor-magn-3d by dropping the relevant code.

this is a pull request of 10 patches for net-next/master.

There is one patch by Wolfram Sang to clean up the build system.
Two patches by Stefan Agner that add vf610 support to the flexcan
driver. Dong Aisheng add support for bosch's m_can core, which is found
in the new freescale ARM SoCs. Sergei Shtylyov improves the rcar_can
driver by supporting all input clocks and adding device tree support.
The next patch is a small cleanup for the bit rate calculation function
by Lad, Prabhakar. And finally a patch by Himangi Saraogi, which
converts the mcp251x driver to use dmam_alloc_coherent.

7132fe4f56 Input: drv260x - add TI drv260x haptics driver
Add the TI drv260x haptics/vibrator driver.  This device uses the input
force feedback to produce a wave form to driver an ERM or LRA actuator
device.

The initial driver supports the devices real time playback mode.  But the
device has additional wave patterns in ROM. This functionality will be
added in future patchsets.

The below patch improves the documentation for the gpio-property. Stephen
Warren has a good example here:
https://github.com/swarren/linux-tegra/commit/09789801

trackpad@4b {
  compatible = "atmel,maxtouch";
  reg = <0x4b>;
  interrupt-parent = <&gpio>;
  interrupts = <TEGRA_GPIO(W, 3) IRQ_TYPE_LEVEL_LOW>;
  linux,gpio-keymap = <0 0 0 BTN_LEFT>;
};

This maps BTN_LEFT to the 4th bit of the T19 message.

On Keystone SOCs, DSP cores can send interrupts to ARM
host using the IRQ controller IP. It provides 28 IRQ
signals to ARM. The IRQ handler running on HOST OS can
identify DSP signal source by analyzing SRCCx bits in
IPCARx registers. This is one of the component used by
the IPC mechanism used on Keystone SOCs.

08fdf65e37 ASoC: fsl_sai: Add asynchronous mode support
SAI supports these operation modes:
1) asynchronous mode
   Both Tx and Rx are set to be asynchronous.
2) synchronous mode (Rx sync with Tx)
   Tx is set to be asynchronous, Rx is set to be synchronous.
3) synchronous mode (Tx sync with Rx)
   Rx is set to be asynchronous, Tx is set to be synchronous.
4) synchronous mode (Tx/Rx sync with another SAI's Tx)
5) synchronous mode (Tx/Rx sync with another SAI's Rx)

* 4) and 5) are beyond this patch because they are related with another SAI.

As the initial version of this SAI driver, it supported 2) as default while
the others were totally missing.

So this patch just adds supports for 1) and 3).

708b4351f0 ASoC: fsl: Add Freescale Generic ASoC Sound Card with ASRC support
The Freescale Generic ASoC Sound Card is a general ASoC DAI Link driver that
can be used, ideally, for all Freescale CPU DAI drivers and external CODECs.

The idea of this generic sound card is a bit like ASoC Simple Card. However,
for Freescale SoCs (especially those released in recent years), most of them
have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
this is a specific feature that might be painstakingly controlled and merged
into the Simple Card driver.

So having this driver will allow all Freescale SoC users to benefit from the
simplification to support a new card and the capability of wide sample rates
support through ASRC.

The driver is initially designed for sound card using I2S or PCM DAI formats.
However, it's also possible to merge those non-I2S/PCM type sound cards, such
as S/PDIF audio and HDMI audio, into this card as long as the merge will not
break the original function and as long as there is something redundant that
can be abstracted along with I2S type sound cards.

As an initial version, it only supports three cards that I can test:
imx-audio-cs42888, a new card that links ESAI with CS42888 CODEC
imx-audio-sgtl5000, just like the old imx-sgtl5000.c driver
imx-audio-wm8962, just like the old imx-wm8962.c driver

The driver is also compatible with the old Device Tree bindings of WM8962 and
SGTL5000. So we may consider to remove those two drivers after this driver is
totally enabled. (It needs to be added into defconfig)

a9ecdc0fdc of/irq: Fix lookup to use 'interrupts-extended' property first
In case the Device Tree blob passed by the boot agent supplies both an
'interrupts-extended' and an 'interrupts' property in order to allow for
older kernels to be usable, prefer the new-style 'interrupts-extended'
property which conveys a lot more information.

This allows us to have bootloaders willingly maintaining backwards
compatibility with older kernels without entirely deprecating the
'interrupts' property.

Update the bindings documentation to describe a situation where both the
'interrupts-extended' and the 'interrupts' property are present, and
which one takes precedence over the other.

ae36e95cf8 The branch contains the following device tree changes the v3.17 merge
window:
 
 Group changes to the device tree. In preparation for adding device tree
 overlay support, OF_DYNAMIC is reworked so that a set of device tree
 changes can be prepared and applied to the tree all at once. OF_RECONFIG
 notifiers see the most significant change here so that users always get
 a consistent view of the tree. Notifiers generation is moved from before
 a change to after it, and notifiers for a group of changes are emitted
 after the entire block of changes have been applied
 
 Automatic console selection from DT. Console drivers can now use
 of_console_check() to see if the device node is specified as a console
 device. If so then it gets added as a preferred console. UART devices
 get this support automatically when uart_add_one_port() is called.
 
 DT unit tests no longer depend on pre-loaded data in the device tree.
 Data is loaded dynamically at the start of unit tests, and then unloaded
 again when the tests have completed.
 
 Also contains a few bugfixes for reserved regions and early memory setup.

3c94f17e72 Thermal: imx: add i.mx6sx thermal support
i.MX6SX has some new features of thermal interrupt function,
there are LOW, HIGH and PANIC irq for thermal sensor, so add
platform data to separate different thermal version;

The reset value of LOW ALARM is 0 which means the highest
temp, so the LOW ALARM will be triggered once irq is enabled,
so we need to correct it before enabling thermal irq;

Enable PANIC ALARM as critical trip point, it will trigger
system reset via SRC module once PANIC IRQ is triggered, it
is pure hardware function, so use it instead of software
reset by cooling device.

The set of changes for this merge window contains two new drivers: one
 for Rockchip SoCs and another for STMicroelectronics STiH4xx SoCs. The
 remainder of the changes are the usual small cleanups such as removing
 redundant OOM messages, signalling that a PWM chip's operations can
 sleep and removing an unneeded dependency.

06b49ea43c This is the bulk of GPIO changes for the v3.17 development
cycle, and this time we got a lot of action going on and
 it will continue:
 
 - The core GPIO library implementation has been split up in
   three different files:
   - gpiolib.c for the latest and greatest and shiny GPIO
     library code using GPIO descriptors only
   - gpiolib-legacy.c for the old integer number space API
     that we are phasing out gradually
   - gpiolib-sysfs.c for the sysfs interface that we are
     not entirely happy with, but has to live on for
     ABI compatibility
 
 - Add a flags argument to *gpiod_get* functions, with some
   backward-compatibility macros to ease transitions. We
   should have had the flags there from the beginning it
   seems, now we need to clean up the mess. There is a plan
   on how to move forward here devised by Alexandre Courbot
   and Mark Brown.
 
 - Split off a special <linux/gpio/machine.h> header for the
   board gpio table registration, as per example from the
   regulator subsystem.
 
 - Start to kill off the return value from gpiochip_remove()
   by removing the __must_check attribute and removing all
   checks inside the drivers/gpio directory. The rationale
   is: well what were we supposed to do if there is an error
   code? Not much: print an error message. And gpiolib already
   does that. So make this function return void eventually.
 
 - Some cleanups of hairy gpiolib code, make some functions
   not to be used outside the library private and make sure
   they are not exported, remove gpiod_lock/unlock_as_irq()
   as the existing function is for driver-internal use and
   fine as it is, delete gpio_ensure_requested() as it is
   not meaningful anymore.
 
 - Support the GPIOF_ACTIVE_LOW flag from gpio_request_one()
   function calls, which is logical since this is already
   supported when referencing GPIOs from e.g. device trees.
 
 - Switch STMPE, intel-mid, lynxpoint and ACPI (!) to use
   the gpiolib irqchip helpers cutting down on GPIO irqchip
   boilerplate a bit more.
 
 - New driver for the Zynq GPIO block.
 
 - The usual incremental improvements around a bunch of
   drivers.
 
 - Janitorial syntactic and semantic cleanups by Jingoo Han,
   and Rickard Strandqvist especially.

50835e977b rapidio/tsi721_dma: rework scatter-gather list handling
Rework Tsi721 RapidIO DMA engine support to allow handling data
scatter/gather lists longer than number of hardware buffer descriptors in
the DMA channel's descriptor list.

The current implementation of Tsi721 DMA transfers requires that number of
entries in a scatter/gather list provided by a caller of
dmaengine_prep_rio_sg() should not exceed number of allocated hardware
buffer descriptors.

This patch removes the limitation by processing long scatter/gather lists
by sections that can be transferred using hardware descriptor ring of
configured size.  It also introduces a module parameter
"dma_desc_per_channel" to allow run-time configuration of Tsi721 hardware
buffer descriptor rings.

aebe17f684 nilfs2: add /sys/fs/nilfs2/features group
This patchset implements creation of sysfs groups and attributes with
the purpose to show NILFS2 volume details, internal state of the driver
and to manage internal state of NILFS2 driver.

Sysfs is a virtual file system that exports information about devices
and drivers from the kernel device model to user space, and is also used
for configuration.  NILFS2 is a complex file system that has segctor
thread, GC thread, checkpoint/snapshot model and so on.  Sysfs namespace
provides native and easy way for: (1) getting info and statistics about
volume state; (2) getting info and configuration of internal subsystems
(segctor thread); (3) snapshots management.

Suggested patchset provides basis for managing segctor thread behaviour
and manipulation by snapshots.  Currently, it informs only about segctor
thread's internal parameters and about mounted snapshots.  But sysfs
interface can provide easy and simple way for deep management of segctor
thread and snapshots.

This patchset provides opportunity to manage interval of periodical
update of superblock (in seconds).  Default value is 10 seconds.  Now a
user can increase this value by means of
nilfs2/<device>/superblock/sb_update_frequency attribute in the case of
necessity.

Also the patchset provides opportunity to get information easily about
key volumes's parameters (free blocks, superblock write count,
superblock update frequency, latest segment info, dirty data blocks
count, count of clean segments, count of dirty segments and so on) in
real time manner.  Such information can be used in scripts for subtle
management of filesystem.

Implemented functionality creates such groups:
(1) /sys/fs/nilfs2 - root group
(2) /sys/fs/nilfs2/features - group contains attributes that describe NILFS
file system driver features
(3) /sys/fs/nilfs2/<device> - group contains attributes that describe file
system partition's details
(4) /sys/fs/nilfs2/<device>/superblock - group contains attributes that describe
superblock's details
(5) /sys/fs/nilfs2/<device>/segctor - group contains attributes that describe
segctor thread activity details
(6) /sys/fs/nilfs2/<device>/segments - group contains attributes that describe
details about volume's segments
(7) /sys/fs/nilfs2/<device>/checkpoints - group contains attributes that describe
details about volume's checkpoints
(8) /sys/fs/nilfs2/<device>/mounted_snapshots - group contains group for every
mounted snapshot
(9) /sys/fs/nilfs2/<device>/mounted_snapshots/<snapshot> - group contains
details about mounted snapshot

This patch (of 9):

This patch adds code of creation /sys/fs/nilfs2 group and
/sys/fs/nilfs2/features group.

The features group contains attributes that describe NILFS
file system driver features:
(1) revision - show current revision of NILFS file system driver.

There are two formats of timestamp output - seconds and human-readable
format.  Every showed timestamp has two sysfs files (time-<xxx> and
time-<xxx>-secs).  One sysfs file (time-<xxx>) shows time in
human-readable format.  Another sysfs file (time-<xxx>-secs) shows time in
seconds.

It was reported by Michael Semon that timestamp output in human-readable
format should be changed from "2014-4-12 14:5:38" to "2014-04-12
14:05:38".  Second version of the patch fixes this issue.

0a31bc97c8 mm: memcontrol: rewrite uncharge API
The memcg uncharging code that is involved towards the end of a page's
lifetime - truncation, reclaim, swapout, migration - is impressively
complicated and fragile.

Because anonymous and file pages were always charged before they had their
page->mapping established, uncharges had to happen when the page type
could still be known from the context; as in unmap for anonymous, page
cache removal for file and shmem pages, and swap cache truncation for swap
pages.  However, these operations happen well before the page is actually
freed, and so a lot of synchronization is necessary:

- Charging, uncharging, page migration, and charge migration all need
  to take a per-page bit spinlock as they could race with uncharging.

- Swap cache truncation happens during both swap-in and swap-out, and
  possibly repeatedly before the page is actually freed.  This means
  that the memcg swapout code is called from many contexts that make
  no sense and it has to figure out the direction from page state to
  make sure memory and memory+swap are always correctly charged.

- On page migration, the old page might be unmapped but then reused,
  so memcg code has to prevent untimely uncharging in that case.
  Because this code - which should be a simple charge transfer - is so
  special-cased, it is not reusable for replace_page_cache().

But now that charged pages always have a page->mapping, introduce
mem_cgroup_uncharge(), which is called after the final put_page(), when we
know for sure that nobody is looking at the page anymore.

For page migration, introduce mem_cgroup_migrate(), which is called after
the migration is successful and the new page is fully rmapped.  Because
the old page is no longer uncharged after migration, prevent double
charges by decoupling the page's memcg association (PCG_USED and
pc->mem_cgroup) from the page holding an actual charge.  The new bits
PCG_MEM and PCG_MEMSW represent the respective charges and are transferred
to the new page during migration.

mem_cgroup_migrate() is suitable for replace_page_cache() as well,
which gets rid of mem_cgroup_replace_page_cache().  However, care
needs to be taken because both the source and the target page can
already be charged and on the LRU when fuse is splicing: grab the page
lock on the charge moving side to prevent changing pc->mem_cgroup of a
page under migration.  Also, the lruvecs of both pages change as we
uncharge the old and charge the new during migration, and putback may
race with us, so grab the lru lock and isolate the pages iff on LRU to
prevent races and ensure the pages are on the right lruvec afterward.

Swap accounting is massively simplified: because the page is no longer
uncharged as early as swap cache deletion, a new mem_cgroup_swapout() can
transfer the page's memory+swap charge (PCG_MEMSW) to the swap entry
before the final put_page() in page reclaim.

Finally, page_cgroup changes are now protected by whatever protection the
page itself offers: anonymous pages are charged under the page table lock,
whereas page cache insertions, swapin, and migration hold the page lock.
Uncharging happens under full exclusion with no outstanding references.
Charging and uncharging also ensure that the page is off-LRU, which
serializes against charge migration.  Remove the very costly page_cgroup
lock and set pc->flags non-atomically.

00501b531c mm: memcontrol: rewrite charge API
These patches rework memcg charge lifetime to integrate more naturally
with the lifetime of user pages.  This drastically simplifies the code and
reduces charging and uncharging overhead.  The most expensive part of
charging and uncharging is the page_cgroup bit spinlock, which is removed
entirely after this series.

Here are the top-10 profile entries of a stress test that reads a 128G
sparse file on a freshly booted box, without even a dedicated cgroup (i.e.
 executing in the root memcg).  Before:

     1.30%           cat  [kernel.kallsyms]   [k] kfree

As you can see, the memcg footprint has shrunk quite a bit.

  35239    9892     400   45531    b1db mm/memcontrol.o

This patch (of 4):

The memcg charge API charges pages before they are rmapped - i.e.  have an
actual "type" - and so every callsite needs its own set of charge and
uncharge functions to know what type is being operated on.  Worse,
uncharge has to happen from a context that is still type-specific, rather
than at the end of the page's lifetime with exclusive access, and so
requires a lot of synchronization.

Rewrite the charge API to provide a generic set of try_charge(),
commit_charge() and cancel_charge() transaction operations, much like
what's currently done for swap-in:

  mem_cgroup_try_charge() attempts to reserve a charge, reclaiming
  pages from the memcg if necessary.

  mem_cgroup_commit_charge() commits the page to the charge once it
  has a valid page->mapping and PageAnon() reliably tells the type.

  mem_cgroup_cancel_charge() aborts the transaction.

This reduces the charge API and enables subsequent patches to
drastically simplify uncharging.

As pages need to be committed after rmap is established but before they
are added to the LRU, page_add_new_anon_rmap() must stop doing LRU
additions again.  Revive lru_cache_add_active_or_unevictable().

A handful of driver-related changes. We've had a bunch of them going in through
 other branches as well, so it's only a part of what we really have this release.
 
 Larger pieces are:
 
 * Removal of a now unused PWM driver for atmel
   - This includes AVR32 changes that have been appropriately acked.
 * Performance counter support for the arm CCN interconnect
 * OMAP mailbox driver cleanups and consolidation
 * PCI and SATA PHY drivers for SPEAr 13xx platforms
 * Redefinition (with backwards compatibility!) of PCI DT bindings for Tegra to
   better model regulators/power.

d4e1f5a14e ARM: SoC device-tree changes for 3.17
Unlike the board branch, this keeps having large sets of changes for
 every release, but that's quite expected and is so far working well.
 
 Most of this is plumbing for various device bindings and new platforms,
 but there's also a bit of cleanup and code removal for things that
 are moved from platform code to DT contents (some OMAP clock code in
 particular).
 
 There's also a pinctrl driver for tegra here (appropriately acked),
 that's introduced this way to make it more bisectable.
 
 I'm happy to say that there were no conflicts at all with this branch
 this release, which means that changes are flowing through our tree as
 expected instead of merged through driver maintainers (or at least not
 done with conflicts).
 
 There are several new boards added, and a couple of SoCs. In no particular
 order:
 
 * Rockchip RK3288 SoC support, including DTS for a dev board that they
   have seeded with some community developers.
 * Better support for Hardkernel Exynos4-based ODROID boards.
 * CCF conversions (and dtsi contents) for several Renesas platforms.
 * Gumstix Pepper (TI AM335x) board support
 * TI eval board support for AM437x
 * Allwinner A23 SoC, very similar to existing ones which mostly has
   resulted in DT changes for support. Also includes support for an Ippo
   tablet with the chipset.
 * Allwinner A31 Hummingbird board support, not to be confused with the
   SolidRun i.MX-based Hummingboard.
 * Tegra30 Apalis board support

Merge tag 'dt-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC device-tree changes from Olof Johansson:
 "Unlike the board branch, this keeps having large sets of changes for
  every release, but that's quite expected and is so far working well.

  Most of this is plumbing for various device bindings and new
  platforms, but there's also a bit of cleanup and code removal for
  things that are moved from platform code to DT contents (some OMAP
  clock code in particular).

  There's also a pinctrl driver for tegra here (appropriately acked),
  that's introduced this way to make it more bisectable.

  I'm happy to say that there were no conflicts at all with this branch
  this release, which means that changes are flowing through our tree as
  expected instead of merged through driver maintainers (or at least not
  done with conflicts).

  There are several new boards added, and a couple of SoCs.  In no
  particular order:

   - Rockchip RK3288 SoC support, including DTS for a dev board that
     they have seeded with some community developers.
   - Better support for Hardkernel Exynos4-based ODROID boards.
   - CCF conversions (and dtsi contents) for several Renesas platforms.
   - Gumstix Pepper (TI AM335x) board support
   - TI eval board support for AM437x
   - Allwinner A23 SoC, very similar to existing ones which mostly has
     resulted in DT changes for support.  Also includes support for an
     Ippo tablet with the chipset.
   - Allwinner A31 Hummingbird board support, not to be confused with
     the SolidRun i.MX-based Hummingboard.
   - Tegra30 Apalis board support"

b3345d7c57 ARM: SoC platform changes for 3.17
This is the bulk of new SoC enablement and other platform changes for 3.17:
 
 * Samsung S5PV210 has been converted to DT and multiplatform
 * Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
 * Kirkwood, one of the popular Marvell platforms, is folded into the
   mvebu platform code, removing mach-kirkwood.
 * Hwmod data for TI AM43xx and DRA7 platforms.
 * More additions of Renesas shmobile platform support
 * Removal of plat-samsung contents that can be removed with S5PV210 being
   multiplatform/DT-enabled and the other two old platforms being removed.
 
 New platforms (most with only basic support right now):
 
 * Hisilicon X5HD2 settop box chipset is introduced
 * Mediatek MT6589 (mobile chipset) is introduced
 * Broadcom BCM7xxx settop box chipset is introduced
 
 + as usual a lot other pieces all over the platform code.

44c916d58b ARM: SoC cleanups for 3.17
This merge window brings a good size of cleanups on various
 platforms. Among the bigger ones:
 
 * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
   lacked active support for quite a while, and after asking around nobody
   showed interest in keeping them around. If needed, they could be
   resurrected in the future but it's more likely that we would prefer
   reintroduction of them as DT and multiplatform-enabled platforms
   instead.
 * OMAP4 controller code register define diet. They defined a lot of registers
   that were never actually used, etc.
 * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
   to drivers/soc so it can be shared with 64-bit code. This also converts them
   over to traditional driver models where possible.
 * Removal of legacy gpio-samsung driver, since the last users have been
   removed (moved to pinctrl)
 
 Plus a bunch of smaller changes for various platforms that sort of
 dissapear in the diffstat for the above. clps711x cleanups, shmobile
 header file refactoring/moves for multiplatform friendliness, some misc
 cleanups, etc.

c704b4ef1a Input: wacom - update the ABI doc according to latest changes
Now the devices show up under hid no matter the connection (for USB
and Bluetooth, not serial nor i2c).

The USB devices can now be easily found under
/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>

The Bluetooth devices could also be found under this path since their
inclusion (April 2010), so this patch fixes the non-precise "hidraw*" path
for them.

The ABI has been unified while setting the LEDs and OLEDs. So Bluetooth
devices lost their own LED selector but use the USB sysfs attribute.
For OLEDs, Bluetooth devices handle only 1-bit images instead of 4 for USB.
The documentation has been updated to match this.

e0b8b78651 This is the bulk pin control changes for the v3.17 merge
development cycle:
 
 - Get rid of the .disable() callback from the driver callback
   vtable. This callback was abused and counterintuitive since
   a pin or group of pins can be said to always be in some
   setting, and never really disabled. We now only enable a
   certain muxing, and move between some certain muxings, we
   never "disable" a mux setting.
 
 - Some janitorial moving the MSM, Samsung and Nomadik and
   drivers to their own subdirectories for a clearer view in
   the subsystem. This will continue.
 
 - Kill off the use of the return value from gpiochip_remove(),
   this will be done in parallel in the GPIO subsystem and
   hopefully not trigger too many unchecked return value
   warnings before we get rid of this altogether.
 
 - A huge set of changes and improvements to the Allwinner
   sunxi drivers especially for their latest A23 and A31 SoCs,
   and some ground work for the new sun8i platform family.
 
 - A large set of Rockchip driver improvements adding support
   for the RK3288 SoC.
 
 - Advances in migration of older Freescale platforms to pin
   control, especially i.MX1.
 
 - Samsung and Exynos improvements.
 
 - Support for the Qualcomm MSM8960 SoC.
 
 - Use the gpiolib irqchip helpers for the ST SPEAr and
   Intel Baytrail drivers.
 
 - A bunch of nice janitorial work done with cppcheck.

   - some janitorial moving the MSM, Samsung and Nomadik and drivers to
     their own subdirectories for a clearer view in the subsystem.  This
     will continue

   - kill off the use of the return value from gpiochip_remove(), this
     will be done in parallel in the GPIO subsystem and hopefully not
     trigger too many unchecked return value warnings before we get rid
     of this altogether

   - a huge set of changes and improvements to the Allwinner sunxi
     drivers especially for their latest A23 and A31 SoCs, and some
     ground work for the new sun8i platform family

   - a large set of Rockchip driver improvements adding support for the
     RK3288 SoC

   - advances in migration of older Freescale platforms to pin control,
     especially i.MX1

   - Samsung and Exynos improvements

b8faf035ea VFS: allow ->d_manage() to declare -EISDIR in rcu_walk mode.
In REF-walk mode, ->d_manage can return -EISDIR to indicate
that the dentry is not really a mount trap (or even a mount point)
and that any mounts or any DCACHE_NEED_AUTOMOUNT flag should be
ignored.

RCU-walk mode doesn't currently support this, so if there is a dentry
with DCACHE_NEED_AUTOMOUNT set but which shouldn't be a mount-trap,
lookup_fast() will always drop in REF-walk mode.

With this patch, an -EISDIR from ->d_manage will always cause mounts
and automounts to be ignored, both in REF-walk and RCU-walk.

66bb0aa077 Here are the PPC and ARM changes for KVM, which I separated because
they had small conflicts (respectively within KVM documentation,
 and with 3.16-rc changes).  Since they were all within the subsystem,
 I took care of them.
 
 Stephen Rothwell reported some snags in PPC builds, but they are all
 fixed now; the latest linux-next report was clean.
 
 New features for ARM include:
 - KVM VGIC v2 emulation on GICv3 hardware
 - Big-Endian support for arm/arm64 (guest and host)
 - Debug Architecture support for arm64 (arm32 is on Christoffer's todo list)
 
 And for PPC:
 - Book3S: Good number of LE host fixes, enable HV on LE
 - Book3S HV: Add in-guest debug support
 
 This release drops support for KVM on the PPC440.  As a result, the
 PPC merge removes more lines than it adds. :)
 
 I also included an x86 change, since Davidlohr tied it to an independent
 bug report and the reporter quickly provided a Tested-by; there was no
 reason to wait for -rc2.

Pull powerpc updates from Ben Herrenschmidt:
 "This is the powerpc new goodies for 3.17.  The short story:

  The biggest bit is Michael removing all of pre-POWER4 processor
  support from the 64-bit kernel.  POWER3 and rs64.  This gets rid of a
  ton of old cruft that has been bitrotting in a long while.  It was
  broken for quite a few versions already and nobody noticed.  Nobody
  uses those machines anymore.  While at it, he cleaned up a bunch of
  old dusty cabinets, getting rid of a skeletton or two.

  Then, we have some base VFIO support for KVM, which allows assigning
  of PCI devices to KVM guests, support for large 64-bit BARs on
  "powernv" platforms, support for HMI (Hardware Management Interrupts)
  on those same platforms, some sparse-vmemmap improvements (for memory
  hotplug),

  There is the usual batch of Freescale embedded updates (summary in the

0c6287ec12 drm/panel: Changes for v3.17-rc1
Panels can now be more finely controlled via .prepare() and .unprepare()
 callbacks in addition to .enable() and .disable(). New kerneldoc details
 what they are supposed to do and when they should be called.
 
 The simple panel driver gained support for a couple of new panels and it
 is now possible to specify additional delays during power up and power
 down sequences if panels require it.
 
 DSI devices can now advertise that they support non-continuous clock
 mode which will allow DSI host controllers to disable the high speed
 clock after transmissions to save power.

Pull ACPI and power management updates from Rafael Wysocki:
 "Again, ACPICA leads the pack (47 commits), followed by cpufreq (18
  commits) and system suspend/hibernation (9 commits).

  From the new code perspective, the ACPICA update brings ACPI 5.1 to
  the table, including a new device configuration object called _DSD
  (Device Specific Data) that will hopefully help us to operate device
  properties like Device Trees do (at least to some extent) and changes
  related to supporting ACPI on ARM.

  Apart from that we have hibernation changes making it use radix trees
  to store memory bitmaps which should speed up some operations carried
  out by it quite significantly.  We also have some power management
  changes related to suspend-to-idle (the "freeze" sleep state) support
  and more preliminary changes needed to support ACPI on ARM (outside of
  ACPICA).

  The rest is fixes and cleanups pretty much everywhere.

  Specifics:

   - ACPICA update to upstream version 20140724.  That includes ACPI 5.1
     material (support for the _CCA and _DSD predefined names, changes
     related to the DMAR and PCCT tables and ARM support among other

 using LIO now), a partial PCI MSI-X update, more multi-queue updates,
 conversion to 64 bit LUNs (so we could theoretically cope with any LUN
 returned by a device) and placeholder support for the ZBC device type (Shingle

930e0312bc sound updates for 3.17-rc1
There've been many updates in ASoC side at this time, especially the
 framework enhancement for multiple CODECs on a single DAI and more
 componentization works.  The only major change in ALSA core is the
 addition of timestamp type in sw_params field.  This should behave in
 backward compatible way.  Other than that, there are lots of small
 changes and new drivers in wide range, including a large code cut in
 HD-audio driver for deprecated static quirks.  Some highlights are
 below:
 
 ALSA Core:
 - Add the new timestamp type field to sw_params to choose
   MONOTONIC_RAW type
 
 HD-audio:
 - Continued conversion to standard printk macros, generic code
   cleanups
 - Removal of obsoleted static quirk codes for Conexant and C-Media
   codecs
 - Fixups for HP Envy TS, Dell XPS 15, HP and Dell mute/mic LED,
   Gigabyte BXBT-2807 mobo
 - Intel Braswell support
 
 ASoC:
 - Support for multiple CODECs attached to a single DAI, enabling
   systems with for example multiple DAC/speaker drivers on a single
  link, contributed by Benoit Cousson based on work from Misael Lopez
  Cruz
 - Support for byte controls larger than 256 bytes based on the use of
   TLVs contributed by Omair Mohammed Abdullah
 - More componentisation work from Lars-Peter Clausen
 - The remainder of the conversions of CODEC drivers to params_width()
   by Mark Brown
 - Drivers for Cirrus Logic CS4265, Freescale i.MX ASRC blocks, Realtek
   RT286 and RT5670, Rockchip RK3xxx I2S controllers and Texas
   Instruments TAS2552
 - Lots of updates and fixes, especially to the DaVinci, Intel,
   Freescale, Realtek, and rcar drivers

Pull sound updates from Takashi Iwai:
 "There've been many updates in ASoC side at this time, especially the
  framework enhancement for multiple CODECs on a single DAI and more
  componentization works.

  The only major change in ALSA core is the addition of timestamp type
  in sw_params field.  This should behave in backward compatible way.

  Other than that, there are lots of small changes and new drivers in
  wide range, including a large code cut in HD-audio driver for
  deprecated static quirks.  Some highlights are below:

  ALSA Core:
   - Add the new timestamp type field to sw_params to choose
     MONOTONIC_RAW type

  HD-audio:
   - Continued conversion to standard printk macros, generic code
     cleanups
   - Removal of obsoleted static quirk codes for Conexant and C-Media
     codecs
   - Fixups for HP Envy TS, Dell XPS 15, HP and Dell mute/mic LED,
     Gigabyte BXBT-2807 mobo
   - Intel Braswell support

  ASoC:
   - Support for multiple CODECs attached to a single DAI, enabling
     systems with for example multiple DAC/speaker drivers on a single
     link, contributed by Benoit Cousson based on work from Misael Lopez
     Cruz
   - Support for byte controls larger than 256 bytes based on the use of
     TLVs contributed by Omair Mohammed Abdullah
   - More componentisation work from Lars-Peter Clausen
   - The remainder of the conversions of CODEC drivers to params_width()
     by Mark Brown
   - Drivers for Cirrus Logic CS4265, Freescale i.MX ASRC blocks,
     Realtek RT286 and RT5670, Rockchip RK3xxx I2S controllers and Texas
     Instruments TAS2552
   - Lots of updates and fixes, especially to the DaVinci, Intel,
     Freescale, Realtek, and rcar drivers"

1d023284c3 list: fix order of arguments for hlist_add_after(_rcu)
All other add functions for lists have the new item as first argument
and the position where it is added as second argument.  This was changed
for no good reason in this function and makes using it unnecessary
confusing.

The name was changed to hlist_add_behind() to cause unconverted code to
generate a compile error instead of using the wrong parameter order.

23b2899f7f printk: allow increasing the ring buffer depending on the number of CPUs
The default size of the ring buffer is too small for machines with a
large amount of CPUs under heavy load.  What ends up happening when
debugging is the ring buffer overlaps and chews up old messages making
debugging impossible unless the size is passed as a kernel parameter.
An idle system upon boot up will on average spew out only about one or
two extra lines but where this really matters is on heavy load and that
will vary widely depending on the system and environment.

There are mechanisms to help increase the kernel ring buffer for tracing
through debugfs, and those interfaces even allow growing the kernel ring
buffer per CPU.  We also have a static value which can be passed upon
boot.  Relying on debugfs however is not ideal for production, and
relying on the value passed upon bootup is can only used *after* an
issue has creeped up.  Instead of being reactive this adds a proactive
measure which lets you scale the amount of contributions you'd expect to
the kernel ring buffer under load by each CPU in the worst case
scenario.

We use num_possible_cpus() to avoid complexities which could be
introduced by dynamically changing the ring buffer size at run time,
num_possible_cpus() lets us use the upper limit on possible number of
CPUs therefore avoiding having to deal with hotplugging CPUs on and off.
This introduces the kernel configuration option LOG_CPU_MAX_BUF_SHIFT
which is used to specify the maximum amount of contributions to the
kernel ring buffer in the worst case before the kernel ring buffer flips
over, the size is specified as a power of 2.  The total amount of
contributions made by each CPU must be greater than half of the default
kernel ring buffer size (1 << LOG_BUF_SHIFT bytes) in order to trigger
an increase upon bootup.  The kernel ring buffer is increased to the
next power of two that would fit the required minimum kernel ring buffer
size plus the additional CPU contribution.  For example if LOG_BUF_SHIFT
is 18 (256 KB) you'd require at least 128 KB contributions by other CPUs
in order to trigger an increase of the kernel ring buffer.  With a
LOG_CPU_BUF_SHIFT of 12 (4 KB) you'd require at least anything over > 64
possible CPUs to trigger an increase.  If you had 128 possible CPUs the
amount of minimum required kernel ring buffer bumps to:

   ((1 << 18) + ((128 - 1) * (1 << 12))) / 1024 = 764 KB

Since we require the ring buffer to be a power of two the new required
size would be 1024 KB.

This CPU contributions are ignored when the "log_buf_len" kernel
parameter is used as it forces the exact size of the ring buffer to an
expected power of two value.

 "A rather large update of timers, timekeeping & co

   - Core timekeeping code is year-2038 safe now for 32bit machines.
     Now we just need to fix all in kernel users and the gazillion of
     user space interfaces which rely on timespec/timeval :)

   - Better cache layout for the timekeeping internal data structures.

   - Proper nanosecond based interfaces for in kernel users.

   - Tree wide cleanup of code which wants nanoseconds but does hoops
     and loops to convert back and forth from timespecs.  Some of it
     definitely belongs into the ugly code museum.

   - Consolidation of the timekeeping interface zoo.

   - A fast NMI safe accessor to clock monotonic for tracing.  This is a
     long standing request to support correlated user/kernel space
     traces.  With proper NTP frequency correction it's also suitable
     for correlation of traces accross separate machines.

   - Checkpoint/restart support for timerfd.

   - A few NOHZ[_FULL] improvements in the [hr]timer code.

   - Code move from kernel to kernel/time of all time* related code.

   - New clocksource/event drivers from the ARM universe.  I'm really
     impressed that despite an architected timer in the newer chips SoC
     manufacturers insist on inventing new and differently broken SoC
     specific timers.

[ Ed. "Impressed"? I don't think that word means what you think it means ]

   - Another round of code move from arch to drivers.  Looks like most
     of the legacy mess in ARM regarding timers is sorted out except for
     a few obnoxious strongholds.

91c2ff7708 regulator: Updates for v3.17
A couple of nice new features this month, the ability to map regulators
 in order to allow voltage control by external coprocessors is something
 people have been asking for for a long time.
 
  - Improved support for switch only "regulators", allowing current state
    to be read from the parent regulator but no setting.
  - Support for obtaining the register access method used to set
    voltages, for use in systems which can offload control of this to a
    coprocessor (typically for DVFS).
  - Support for Active-Semi AC8846, Dialog DA9211 and Texas Instruments
    TPS65917.

RFCOMM, another fix to an issue with ADV_DIRECT_IND and one for ADV_IND with
auto-connection handling.  Last, we added support for reading the codec and
MWS setting for controllers that support these features.'

Additionally there are fixes to LE scanning, an update to conform to the 4.1
core specification as well as fixes for tracking the page scan state. All
of these fixes are important for 3.17."

And,

"We've got:

- 6lowpan fixes/cleanups
- A couple crash fixes, one for the Marvell HCI driver and another in LE SMP.
- Fix for an incorrect connected state check
- Fix for the bondable requirement during pairing (an issue which had
  crept in because of using "pairable" when in fact the actual meaning
  was "bondable" (these have different meanings in Bluetooth)"

Along with those are some late-breaking hardware support patches in
brcmfmac and b43 as well as a stray ath9k patch.

aa8dbeee5e Documentation: headers_install.txt is part of kbuild
'headers_install.txt' from Documentation/make/ is related to Kbuild
so it must be moved in Documentation/kbuild/ directory.

As Documentation/make/ directory has only one file, it will be removed
as a consequence of moving 'headers_install.txt'.

53ee983378 Staging driver patches for 3.17-rc1
Here's the big pull request for the staging driver tree for 3.17-rc1.
 
 Lots of things in here, over 2000 patches, but the best part is this:
  1480 files changed, 39070 insertions(+), 254659 deletions(-)
 
 Thanks to the great work of Kristina Martšenko, 14 different staging
 drivers have been removed from the tree as they were obsolete and no one
 was willing to work on cleaning them up.  Other than the driver
 removals, loads of cleanups are in here (comedi, lustre, etc.) as well
 as the usual IIO driver updates and additions.
 
 All of this has been in the linux-next tree for a while.

96b1b97110 Merge branch 'drm_kms_for_next-v8' of git://git.linaro.org/people/benjamin.gaignard/kernel into drm-next
This series of patches add the support of DRM/KMS drivers for STMicroelectronics
chipsets stih416 and stih407.

Hardware is split in two main blocks: Compositor and TVout. Each of them
includes specific hardware IPs and the display timing are controlled by a specific
Video Timing Generator hardware IP (VTG).

Compositor is made of the follow hardware IPs:
 - GDP (Generic Display Pipeline) which is an entry point for graphic (RGB)
   buffers
 - VDP (Video Diplay Pipeline) which is an entry point for video (YUV) buffers
 - HQVDP (High Quality Video Display Processor) that supports scaling,
   deinterlacing and some miscellaneous image quality improvements.
   It fetches the Video decoded buffers from memory, processes them and pushes
   them to the Compositor through a HW dedicated bus.
 - Mixer is responsible of mixing all the entries depending of their
   respective z-order and layout

TVout is divided in 3 parts:
 - HDMI to generate HDMI signals, depending of chipset version HDMI phy can
   change.
 - HDA to generate signals for HD analog TV
 - VIP to control/switch data path coming from Compositor

On stih416 compositor and Tvout are on different dies so a Video Trafic Advance
inter-die Communication mechanism (VTAC) is needed.

In addition of the drivers for the IPs listed before a thin I2C driver (hdmiddc) is used
by HDMI driver to retrieve EDID for monitor.

To unify interfaces of GDP and VDP we create a "layer" interface called by
compositor to control both GPD and VDP.

Hardware have memory contraints (alignment, contiguous) so we use CMA drm helpers functions
to allocate frame buffer.

File naming convention is:
 - sti_* for IPs drivers
 - sti_drm_* for drm functions implementation.

  - Context tracking support (NO_HZ_FULL) which narrowly missed 3.16
  - vDSO layout rework following Andy's work on x86
  - TEXT_OFFSET fuzzing for bootloader testing
  - /proc/cpuinfo tidy-up
  - Preliminary work to support 48-bit virtual addresses, but this is

b8c0aa46b3 This pull request has a lot of work done. The main thing is the changes
to the ftrace function callback infrastructure. It's introducing a
 way to allow different functions to call directly different trampolines
 instead of all calling the same "mcount" one.
 
 The only user of this for now is the function graph tracer, which always
 had a different trampoline, but the function tracer trampoline was called
 and did basically nothing, and then the function graph tracer trampoline
 was called. The difference now, is that the function graph tracer
 trampoline can be called directly if a function is only being traced by
 the function graph trampoline. If function tracing is also happening on
 the same function, the old way is still done.
 
 The accounting for this takes up more memory when function graph tracing
 is activated, as it needs to keep track of which functions it uses.
 I have a new way that wont take as much memory, but it's not ready yet
 for this merge window, and will have to wait for the next one.
 
 Another big change was the removal of the ftrace_start/stop() calls that
 were used by the suspend/resume code that stopped function tracing when
 entering into suspend and resume paths. The stop of ftrace was done
 because there was some function that would crash the system if one called
 smp_processor_id()! The stop/start was a big hammer to solve the issue
 at the time, which was when ftrace was first introduced into Linux.
 Now ftrace has better infrastructure to debug such issues, and I found
 the problem function and labeled it with "notrace" and function tracing
 can now safely be activated all the way down into the guts of suspend
 and resume.
 
 Other changes include clean ups of uprobe code.
 Clean up of the trace_seq() code.
 And other various small fixes and clean ups to ftrace and tracing.

e4ca4308c0 The clock framework changes for 3.17 are mostly additions of new clock
drivers and fixes/enhancements to existing clock drivers. There are also
 some non-critical fixes and improvements to the framework core.
 
 Changes to the clock framework core include:
 * improvements to printks on errors
 * flattening the previously hierarchal structure of per-clock entries
   in debugfs
 * allow per-clock debugfs entries that are specific to a particular
   clock driver
 * configure initial clock parent and/or initial clock rate from Device
   Tree
 * several feature enhancements to the composite clock type
 * misc fixes
 
 New clock drivers added include:
 * TI Palmas PMIC
 * Allwinner A23 SoC
 * Qualcomm APQ8084 and IPQ8064 SoCs
 * Rockchip rk3188, rk3066 and rk3288 SoCs
 * STMicroelectronics STiH407 SoC
 * Cirrus Logic CLPS711X SoC
 
 Many fixes, feature enhancements and further clock tree support for
 existing clock drivers also were merged, such as Samsung's "ARMCLK down"
 power saving feature for their Exynos4 & Exynos5 SoCs.

Pull cgroup changes from Tejun Heo:
 "Mostly changes to get the v2 interface ready.  The core features are
  mostly ready now and I think it's reasonable to expect to drop the
  devel mask in one or two devel cycles at least for a subset of
  controllers.

   - cgroup added a controller dependency mechanism so that block cgroup
     can depend on memory cgroup.  This will be used to finally support
     IO provisioning on the writeback traffic, which is currently being
     implemented.

   - The v2 interface now uses a separate table so that the interface
     files for the new interface are explicitly declared in one place.
     Each controller will explicitly review and add the files for the
     new interface.

   - cpuset is getting ready for the hierarchical behavior which is in
     the similar style with other controllers so that an ancestor's
     configuration change doesn't change the descendants' configurations
     irreversibly and processes aren't silently migrated when a CPU or
     node goes down.

  All the changes are to the new interface and no behavior changed for
  the multiple hierarchies"

e9e3bdffe3 ASoC: Updates for v3.17
This has been a pretty exciting release in terms of the framework, we've
 finally got support for multiple CODECs attached to a single DAI link
 which has been something there's been interest in as long as I've been
 working on ASoC.  A big thanks to Benoit and Misael for their work on
 this.
 
 Otherwise it's been a fairly standard release for development, including
 more componentisation work from Lars-Peter and a good selection of both
 CODEC and CPU drivers.
 
  - Support for multiple CODECs attached to a single DAI, enabling
    systems with for example multiple DAC/speaker drivers on a single
    link, contributed by Benoit Cousson based on work from Misael Lopez
    Cruz.
  - Support for byte controls larger than 256 bytes based on the use of
    TLVs contributed by Omair Mohammed Abdullah.
  - More componentisation work from Lars-Peter Clausen.
  - The remainder of the conversions of CODEC drivers to params_width()
  - Drivers for Cirrus Logic CS4265, Freescale i.MX ASRC blocks, Realtek
    RT286 and RT5670, Rockchip RK3xxx I2S controllers and Texas Instruments
    TAS2552.
  - Lots of updates and fixes, especially to the DaVinci, Intel,
    Freescale, Realtek, and rcar drivers.

41e69778c8 drm/msm: DT support for 8960/8064 (v3)
Now that we (almost) have enough dependencies in place (MMCC, RPM, etc),
add necessary DT support so that we can use drm/msm on upstream kernel.

v2: update for review comments
v3: rebase on component helper changes
