cpu/hotplug: Create SMT sysfs interface for all arches
Make the /sys/devices/system/cpu/smt/* files available on all arches, so user space has a consistent way to detect whether SMT is enabled. The 'control' file now shows 'notimplemented' for architectures which don't yet have CONFIG_HOTPLUG_SMT.

batman-adv: ABI: Mark sysfs files as deprecated
The sysfs files are replaced by the batadv generic netlink family. The old sysfs configuration interface was frowned upon by other kernel developers. But the files cannot be removed immediately because userspace tools might still depend on it. Instead schedule for its removal in 2021.

f2fs-for-5.1-rc1
We've continued mainly to fix bugs in this round, as f2fs has been shipped
in more devices. Especially, we've focused on stabilizing checkpoint=disable
feature, and provided some interfaces for QA.
Enhancement:
- expose FS_NOCOW_FL for pin_file
- run discard jobs at unmount time with timeout
- tune discarding thread to avoid idling which consumes power
- some checking codes to address vulnerabilities
- give random value to i_generation
- shutdown with more flags for QA
Bug fix:
- clean up stale objects when mount is failed along with checkpoint=disable
- fix system being stuck due to wrong count by atomic writes
- handle some corrupted disk cases
- fix a deadlock in f2fs_read_inline_dir
We've also added some minor build errors and clean-up patches.

USB/PHY patches for 5.1-rc1
Here is the big USB/PHY driver pull request for 5.1-rc1.

Char/Misc driver patches for 5.1-rc1
Here is the big char/misc driver patch pull request for 5.1-rc1. The largest thing by far is the new habanalabs driver for their AI accelerator chip. For now it is in the drivers/misc directory but will probably move to a new directory soon along with other drivers of this type. Other than that, just the usual set of individual driver updates and fixes. There's an "odd" merge in here from the DRM tree that they asked me to do as the MEI driver is starting to interact with the i915 driver, and it needed some coordination.

habanalabs: add sysfs and hwmon support
This patch add the sysfs and hwmon entries that are exposed by the driver. Goya has several sensors, from various categories such as temperature, voltage, current, etc. The driver exposes those sensors in the standard hwmon mechanism. In addition, the driver exposes a couple of interfaces in sysfs, both for configuration and for providing status of the device or driver. The configuration attributes is for Power Management: - Automatic or manual - Frequency value when moving to high frequency mode - Maximum power the device is allowed to consume The rest of the attributes are read-only and provide the following information: - Versions of the various firmwares running on the device - Contents of the device's EEPROM - The device type (currently only Goya is supported) - PCI address of the device (to allow user-space to connect between /dev/hlX to PCI address) - Status of the device (operational, malfunction, in_reset) - How many processes are open on the device's file Reviewed-by: Mike Rapoport <rppt@linux.ibm.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

First set of new device support, features and cleanup for IIO in the 5.1 cycle
A number of interesting new devices supported plus a good set of staging
cleanup including one graduation and one drop.
New device support
* ad56886
- Add support for AD5674R/AD5679R with some minor driver changes to support
more channels.
* ad7768
- New driver and dt bindings for this 24 bit ADC.
* max44009
- New driver and dt bindings for this ambient light sensor.
* mpu6050
- Support the ICM 20602 IMU. Minor tweaks due to slightly different
register map.
* NPCM adc
- New driver and dt bindings for this BMC ADC.
* Sensiron SGP30
- Modifiers for ethanol and H2.
- New driver and dt bindings.
- Follow patch added self cleaning support.
* Sensiron SPS30
- New channel type for mass concentration.
- New driver and bindings.
- Minor tidy up patch followed (drop fmt specifier as unused)
* st_pressure
- lps22hh support. ID plus information structures and dt bindings.
* ti-ads124s08
- Add binding doc and driver.
Staging graduations
* ad7606 driver and bindings.
Staging drops
* ad7152 CDC driver dropped. This part is near EoL and no one is known
to be using it. If anyone surfaces obviously we can bring the driver
back. If not, good to drop it to avoid wasting anyone's time cleaning
it up.
New features
* bme680
- DT support and bindings doc.
* isl29018
- Add regulator for VCC.
* mag3110
- Add regulators for supplies.
* meson-saradc
- Support the temperature sensors of more SoCs.
* mma8452
- Add regulators for power suplies and binding docs to reflect them.
* st-accel
- Support the undocumented but it seems fairly common _ONT ACPI method
to specify orientation of the sensor.
Cleanup, minor fixes and fixes for staging driver that have been broken a
long time
* ad5933
- Drop platform data alternative to specifying the reference voltage
using a regulator.
- Use the clock framework to contorl the reference clock.
- Add a DT binding doc to cover the defacto binding.
* ad7280a
- Split up some big functions to improve readability.
* ad7606
- Allow for timeout if interrupt never occurs.
- Use devm functions to simplify probe and remove.
- Use the find_closest macro to avoid need for precise values from
userspace.
- Add missing vendor prefixes for various DT properties. Note the
driver is in staging still and there are no known devicetrees.
- Add explict OF device ID table.
- Simplify the Kconfig choices
- Change to a threaded IRQ.
- SPDX and simple stype fixes.
* ad7816
- Drop unnecessary variable init.
* ad9523
- Check a return value that was ignored.
* ad9833
- Drop platform data. It was just setting most values to the hardware
defaults.
- Use the clock framework to provide the input clock.
* adt7316 (lots of staging cleanup)
- Fix some wrong register / bit definitions
- Invert the logic of the check for an ldac pin so it actually makes sense.
- Read the right register to get internal vref settings
- Allow adt751x chips to use the internal vref for all DAC channels rather
than a subset.
- Remove dac vref bypass control from parts that don't have one.
- Make the store DAC update mode function consistent with the show one.
- Fix some spellings and other minor tidy up.
- Avoid passing irq numbers around by putting all the irq logic in
one place.
- Fix an issue with the resolution of DAC control.
- Fix support of the high resolution DAC mode (for temp proportional output)
where supported.
- Fix DAC read and write calculations.
* st_lsm6dsx

zram: idle writeback fixes and cleanup
This patch includes some fixes and cleanup for idle-page writeback.
1. writeback_limit interface
Now writeback_limit interface is rather conusing. For example, once
writeback limit budget is exausted, admin can see 0 from
/sys/block/zramX/writeback_limit which is same semantic with disable
writeback_limit at this moment. IOW, admin cannot tell that zero came
from disable writeback limit or exausted writeback limit.
To make the interface clear, let's sepatate enable of writeback limit to
another knob - /sys/block/zram0/writeback_limit_enable
* before:
while true :
# to re-enable writeback limit once previous one is used up
echo 0 > /sys/block/zram0/writeback_limit
echo $((200<<20)) > /sys/block/zram0/writeback_limit
..
.. # used up the writeback limit budget
* new
# To enable writeback limit, from the beginning, admin should
# enable it.
echo $((200<<20)) > /sys/block/zram0/writeback_limit
echo 1 > /sys/block/zram/0/writeback_limit_enable
while true :
echo $((200<<20)) > /sys/block/zram0/writeback_limit
..
.. # used up the writeback limit budget
It's much strightforward.
2. fix condition check idle/huge writeback mode check
The mode in writeback_store is not bit opeartion any more so no need to
use bit operations. Furthermore, current condition check is broken in
that it does writeback every pages regardless of huge/idle.
3. clean up idle_store
No need to use goto.

Self cleaning is especially useful in cases where sensor undergoes frequent power on/off cycles. In such scenarios it is recommended to turn self cleaning at least once per week in order to maintain reliable measurements. Self cleaning is activated by writing 1 to a dedicated attribute.

Char/Misc driver patches for 4.21-rc1
Here is the big set of char and misc driver patches for 4.21-rc1.
Lots of different types of driver things in here, as this tree seems to
be the "collection of various driver subsystems not big enough to have
their own git tree" lately.
Anyway, some highlights of the changes in here:
- binderfs: is it a rule that all driver subsystems will eventually
grow to have their own filesystem? Binder now has one to handle the
use of it in containerized systems. This was discussed at the
Plumbers conference a few months ago and knocked into mergable shape
very fast by Christian Brauner. Who also has signed up to be
another binder maintainer, showing a distinct lack of good judgement :)
- binder updates and fixes
- mei driver updates
- fpga driver updates and additions
- thunderbolt driver updates
- soundwire driver updates
- extcon driver updates
- nvmem driver updates
- hyper-v driver updates
- coresight driver updates
- pvpanic driver additions and reworking for more device support
- lp driver updates. Yes really, it's _finally_ moved to the proper
parallal port driver model, something I never thought I would see
happen. Good stuff.
- other tiny driver updates and fixes.
All of these have been in linux-next for a while with no reported
issues.

Pull block updates from Jens Axboe:
"This is the main pull request for block/storage for 4.21.
Larger than usual, it was a busy round with lots of goodies queued up.
Most notable is the removal of the old IO stack, which has been a long
time coming. No new features for a while, everything coming in this
week has all been fixes for things that were previously merged.
This contains:
- Use atomic counters instead of semaphores for mtip32xx (Arnd)
- Cleanup of the mtip32xx request setup (Christoph)
- Fix for circular locking dependency in loop (Jan, Tetsuo)
- bcache (Coly, Guoju, Shenghui)
* Optimizations for writeback caching
* Various fixes and improvements
- nvme (Chaitanya, Christoph, Sagi, Jay, me, Keith)
* host and target support for NVMe over TCP
* Error log page support
* Support for separate read/write/poll queues
* Much improved polling
* discard OOM fallback
* Tracepoint improvements
- lightnvm (Hans, Hua, Igor, Matias, Javier)
* Igor added packed metadata to pblk. Now drives without metadata
per LBA can be used as well.
* Fix from Geert on uninitialized value on chunk metadata reads.
* Fixes from Hans and Javier to pblk recovery and write path.
* Fix from Hua Su to fix a race condition in the pblk recovery
code.
* Scan optimization added to pblk recovery from Zhoujie.
* Small geometry cleanup from me.
- Conversion of the last few drivers that used the legacy path to
blk-mq (me)
- Removal of legacy IO path in SCSI (me, Christoph)
- Removal of legacy IO stack and schedulers (me)
- Support for much better polling, now without interrupts at all.
blk-mq adds support for multiple queue maps, which enables us to
have a map per type. This in turn enables nvme to have separate
completion queues for polling, which can then be interrupt-less.
Also means we're ready for async polled IO, which is hopefully
coming in the next release.
- Killing of (now) unused block exports (Christoph)
- Unification of the blk-rq-qos and blk-wbt wait handling (Josef)
- Support for zoned testing with null_blk (Masato)
- sx8 conversion to per-host tag sets (Christoph)
- IO priority improvements (Damien)
- mq-deadline zoned fix (Damien)
- Ref count blkcg series (Dennis)
- Lots of blk-mq improvements and speedups (me)
- sbitmap scalability improvements (me)
- Make core inflight IO accounting per-cpu (Mikulas)
- Export timeout setting in sysfs (Weiping)
- Cleanup the direct issue path (Jianchao)
- Export blk-wbt internals in block debugfs for easier debugging
(Ming)
- Lots of other fixes and improvements"

zram: writeback throttle
If there are lots of write IO with flash device, it could have a wearout problem of storage. To overcome the problem, admin needs to design write limitation to guarantee flash health for entire product life. This patch creates a new knob "writeback_limit" for zram. writeback_limit's default value is 0 so that it doesn't limit any writeback. If admin want to measure writeback count in a certain period, he could know it via /sys/block/zram0/bd_stat's 3rd column. If admin want to limit writeback as per-day 400M, he could do it like below. MB_SHIFT=20 4K_SHIFT=12 echo $((400<<MB_SHIFT>>4K_SHIFT)) > \ /sys/block/zram0/writeback_limit. If admin want to allow further write again, he could do it like below echo 0 > /sys/block/zram0/writeback_limit If admin want to see remaining writeback budget, cat /sys/block/zram0/writeback_limit The writeback_limit count will reset whenever you reset zram (e.g., system reboot, echo 1 > /sys/block/zramX/reset) so keeping how many of writeback happened until you reset the zram to allocate extra writeback budget in next setting is user's job.

zram: add bd_stat statistics
bd_stat represents things that happened in the backing device. Currently it supports bd_counts, bd_reads and bd_writes which are helpful to understand wearout of flash and memory saving.

zram: support idle/huge page writeback
Add a new feature "zram idle/huge page writeback". In the zram-swap use
case, zram usually has many idle/huge swap pages. It's pointless to keep
them in memory (ie, zram).
To solve this problem, this feature introduces idle/huge page writeback to
the backing device so the goal is to save more memory space on embedded
systems.
Normal sequence to use idle/huge page writeback feature is as follows,
while (1) {
# mark allocated zram slot to idle
echo all > /sys/block/zram0/idle
# leave system working for several hours
# Unless there is no access for some blocks on zram,
# they are still IDLE marked pages.
echo "idle" > /sys/block/zram0/writeback
or/and
echo "huge" > /sys/block/zram0/writeback
# write the IDLE or/and huge marked slot into backing device
# and free the memory.
}
Per the discussion at
https://lore.kernel.org/lkml/20181122065926.GG3441@jagdpanzerIV/T/#u,
This patch removes direct incommpressibe page writeback feature
(d2afd25114f4 ("zram: write incompressible pages to backing device")).
Below concerns from Sergey:
== &< ==
"IDLE writeback" is superior to "incompressible writeback".
"incompressible writeback" is completely unpredictable and uncontrollable;
it depens on data patterns and compression algorithms. While "IDLE
writeback" is predictable.
I even suspect, that, *ideally*, we can remove "incompressible writeback".
"IDLE pages" is a super set which also includes "incompressible" pages.
So, technically, we still can do "incompressible writeback" from "IDLE
writeback" path; but a much more reasonable one, based on a page idling
period.
I understand that you want to keep "direct incompressible writeback"
around. ZRAM is especially popular on devices which do suffer from flash
wearout, so I can see "incompressible writeback" path becoming a dead
code, long term.
== &< ==
Below concerns from Minchan:
== &< ==
My concern is if we enable CONFIG_ZRAM_WRITEBACK in this implementation,
both hugepage/idlepage writeck will turn on. However someuser want to
enable only idlepage writeback so we need to introduce turn on/off knob
for hugepage or new CONFIG_ZRAM_IDLEPAGE_WRITEBACK for those usecase. I
don't want to make it complicated *if possible*.
Long term, I imagine we need to make VM aware of new swap hierarchy a
little bit different with as-is. For example, first high priority swap
can return -EIO or -ENOCOMP, swap try to fallback to next lower priority
swap device. With that, hugepage writeback will work tranparently.
So we could regard it as regression because incompressible pages doesn't
go to backing storage automatically. Instead, user should do it via "echo
huge" > /sys/block/zram/writeback" manually.

zram: introduce ZRAM_IDLE flag
To support idle page writeback with upcoming patches, this patch
introduces a new ZRAM_IDLE flag.
Userspace can mark zram slots as "idle" via
"echo all > /sys/block/zramX/idle"
which marks every allocated zram slot as ZRAM_IDLE.
User could see it by /sys/kernel/debug/zram/zram0/block_state.
300 75.033841 ...i
301 63.806904 s..i
302 63.806919 ..hi
Once there is IO for the slot, the mark will be disappeared.
300 75.033841 ...
301 63.806904 s..i
302 63.806919 ..hi
Therefore, 300th block is idle zpage. With this feature,
user can how many zram has idle pages which are waste of memory.

Device properties framework updates for 4.21-rc1
- Introduce "software nodes", analogous to the DT and ACPI firmware
nodes except that they can be created by kernel code, in order to
complement fwnodes representing real firmware nodes when they are
incomplete (for example missing device properties) and to supply
the primary fwnode when the firmware lacks hardware description
for a device completely, and replace the "property_set" struct
fwnode_handle type with software nodes (Heikki Krogerus).
- Clean up the just introduced software nodes support and fix a commet
in the graph-handling code (Colin Ian King, Marco Felsch).

Power management updates for 4.21-rc1
- Add sysadmin documentation for cpuidle (Rafael Wysocki).
- Make it possible to specify a cpuidle governor from kernel
command line, add new cpuidle state sysfs attributes for
governor evaluation, and improve the "polling" idle state
handling (Rafael Wysocki).
- Fix the handling of the "required-opps" DT property in the
operating performance points (OPP) framework, improve the
integration of it with the generic power domains (genpd)
framework, improve the handling of performance states in
them and clean up the idle states vs performance states
separation in genpd (Viresh Kumar, Ulf Hansson).
- Add a cpufreq driver called "qcom-hw" for Qualcomm SoCs using
a hardware engine to control CPU frequency transitions along
with DT bindings for it (Taniya Das).

Existing air quality sensors usually follow this convention and are capable of returning measurements using this unit. IIO currently does not offer suitable channel type for this type of measurements hence this patch adds this. In addition, extra modifiers are introduced used for distinguishing between fine pm1, pm2p5 and coarse pm4, pm10 particle measurements, i.e IIO_MOD_PM1, IIO_MOD_PM25 and IIO_MOD_PM4, IIO_MOD_PM10. pmX consists of particles with aerodynamic diameter less or equal to X micrometers.

thunderbolt: Export IOMMU based DMA protection support to userspace
Recent systems with Thunderbolt ports may support IOMMU natively. In practice this means that Thunderbolt connected devices are placed behind an IOMMU during the whole time it is connected (including during boot) making Thunderbolt security levels redundant. This is called Kernel DMA protection [1] by Microsoft. Some of these systems still have Thunderbolt security level set to "user" in order to support OS downgrade (the older version of the OS might not support IOMMU based DMA protection so connecting a device still relies on user approval). Export this information to userspace by introducing a new sysfs attribute (iommu_dma_protection). Based on it userspace tools can make more accurate decision whether or not authorize the connected device. In addition update Thunderbolt documentation regarding IOMMU based DMA protection.

net: dsa: Fix tagging attribute location
While introducing the DSA tagging protocol attribute, it was added to the DSA
slave network devices, but those actually see untagged traffic (that is their
whole purpose). Correct this mistake by putting the tagging sysfs attribute
under the DSA master network device where this is the information that we need.
While at it, also correct the sysfs documentation mistake that missed the
"dsa/" directory component of the attribute.

drivers: base: Introducing software nodes to the firmware node framework
Software node is a new struct fwnode_handle type that can be used to describe devices in kernel (software). It is meant to complement fwnodes representing real firmware nodes when they are incomplete (for example missing device properties) and to supply the primary fwnode when the firmware lacks hardware description for a device completely. The software node type is really meant to replace the currently used "property_set" struct fwnode_handle type. The handling of struct property_set is glued to the generic device property handling code, and it is not possible to create a struct property_set independently from the device that it is bind to. struct property_set is only created when device properties are added to already initialized struct device, and control of it is only possible from the generic property handling code. Software nodes are instead designed to be created independently from the device entries (struct device). It makes them much more flexible, as then the device meant to be bind to the node can be created at a later time, and from another location. It is also possible to bind multiple devices to a single software node if needed. The software node implementation also includes support for node hierarchy, which was the main motivation for this commit. The node hierarchy was something that was requested for the struct property_set, but it did not seem reasonable to try to extend the property_set support for that purpose. struct property_set was really meant only for device property handling like the name suggests. Support for struct property_set is not yet removed in this commit, but it will be in the following one.

- remove mutex_lock() from timer callback, which would trigger
problems related to sleeping in atomic context, the removal is
harmless since mutex protection turned out to be redundant in this
case
- fix pattern parsing to properly handle intervals with brightness == 0

Staging/IIO patches for 4.20-rc1
Here is the big staging and IIO driver pull request for 4.20-rc1.
There are lots of things here, we ended up adding more lines than
removing, thanks to a large influx of Comedi National Instrument device
support. Someday soon we need to get comedi out of staging...
Other than the comedi drivers, the "big" things here are:
- new iio drivers
- delete dgnc driver (no one used it and no one had the hardware
anymore)
- vbox driver updates and fixes
- erofs fixes
- tons and tons of tiny checkpatch fixes for almost all staging
drivers
All of these have been in linux-next, with the last few happening a bit
"late" due to them getting stuck on my laptop during travel to the
Mantainers summit.
When merging with your tree, there will be 2 merge conflicts, both files
will be simple to resolve, just delete them :)

f2fs-for-4.20-rc1
In this round, we've added 1) superblock checksum feature, 2) implemented new mount option which we can disable/enable checkpoint to provide atomic updates of entire filesystem, 3) refactored quota operations to enhance its consistency along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward recovery flow to resurrect any fsync'ed inode metadata. Enhancement: - add checksum to keep superblock contents more safe - add checkpoint=disable/enable to support A/B update of entire filesystem - use plug for readahead IO in readdir - add more IO counts to avoid block layer hacks Bug fix: - prevent data corruption issue for hardware encryption - fix IO hang issues when GC is heavily triggered - add missing up_read in __write_node_page - recover inode metadata during roll-forward recovery flow - fix null pointer dereference issue in wrongly configured discard map There are some more sanity checks and minor bug fixes as well. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAlvPzt4ACgkQQBSofoJI UNJLfg/8Ch9TWfbeUEH+6ioJ4pdURHmb/gFOQRSGX8Nu+HkuPJQD8pqlheK7n5g7 Pw3K6NLXHmL2d8xSNFbBwYmUSAeoXTc0J4nqX0sUJ6m7SKsuQ45Qe3A90faKEoAA ce7flWKVI+aJcGurBe99GOM69ptfyjb1w/8UGB0pcXUDq4oaRv5a1UtAAm92WF7H 4/7jYD3ub5aeSynwe16wWR4B5aXJT0l0FcZYicI6IRY1mOjMtXuQt72AY+ffSzBt yQ6qb8OEl3xpfQZHHH00ZfvarkTBzXJGZwquiPX/CPzVcee8cOqPp+XZqN7CXBEr 9ItezxYiUxOkKCl12Al8DynHZa6o2kEnWxgd49WkL/cNdInnvf5MD0kdfCV3KfQa CAR0UVe2yTg5mGLemtTSWveLdHfI7+LhDmURuXmoTUa9GWldw0413qqVVypcsizv QOAS86hSicrVK+bDnCA70i8Xxw7YEnAyrfCcgihU84NZSi7nTPUYj4xtMd9SzRnK JO8gA79D7lcWaxUS4r9I+JBDwWcfMQZRPS7PFbvoGWilIwsEaocCPYNgtjCTsAsK 1fePqiF/265Q4lapmEhEjhuQSNH2xfJQZ4ux1OU+eS3OTDjbEAFBeVPZImh7Mo7F dkpXQwfcqAXPzOM4QAJ6hFX40D8SWMAlId6XGiIfJlrFmEUAxBk= =VDw4 -----END PGP SIGNATURE----- Merge tag 'f2fs-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added 1) superblock checksum feature, 2) implemented new mount option which we can disable/enable checkpoint to provide atomic updates of entire filesystem, 3) refactored quota operations to enhance its consistency along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward recovery flow to resurrect any fsync'ed inode metadata.

Power management updates for 4.20-rc1
- Backport hibernation bug fixes from x86-64 to x86-32 and
consolidate hibernation handling on x86 to allow 32-bit
systems to work in all of the cases in which 64-bit ones
work (Zhimin Gu, Chen Yu).
- Fix hibernation documentation (Vladimir D. Seleznev).
- Update the menu cpuidle governor to fix a couple of issues
with it, make it more efficient in some cases and clean it
up (Rafael Wysocki).
- Rework the cpuidle polling state implementation to make it
more efficient (Rafael Wysocki).
- Clean up the cpuidle core somewhat (Fieah Lim).
- Fix the cpufreq conservative governor to take policy limits
into account properly in some cases (Rafael Wysocki).
- Add support for retrieving guaranteed performance information
to the ACPI CPPC library and make the intel_pstate driver use
it to expose the CPU base frequency via sysfs on systems with
the hardware-managed P-states (HWP) feature enabled (Srinivas
Pandruvada).
- Fix clang warning in the CPPC cpufreq driver (Nathan Chancellor).
- Get rid of device_node.name printing from cpufreq (Rob Herring).
- Remove unnecessary unlikely() from the cpufreq core (Igor Stoppa).
- Add support for the r8a7744 SoC to the cpufreq-dt driver (Biju Das).
- Update the dt-platdev cpufreq driver to allow RK3399 to have
separate tunables per cluster (Dmitry Torokhov).
- Fix the dma_alloc_coherent() usage in the tegra186 cpufreq driver
(Christoph Hellwig).
- Make the imx6q cpufreq driver read OCOTP through nvmem for
imx6ul/imx6ull (Anson Huang).
- Fix several bugs in the operating performance points (OPP)
framework and make it more stable (Viresh Kumar, Dave Gerlach).
- Update the devfreq subsystem to take changes in the APIs used
by into account, fix some issues with it and make it stop
print device_node.name directly (Bjorn Andersson, Enric Balletbo
i Serra, Matthias Kaehlcke, Rob Herring, Vincent Donnefort, zhong
jiang).
- Prepare the generic power domains (genpd) framework for dealing
with domains containing CPUs (Ulf Hansson).
- Prevent sysfs attributes representing low-power S0 residency
counters from being exposed if low-power S0 support is not
indicated in ACPI FADT (Rajneesh Bhardwaj).
- Get rid of custom CPU features macros for Intel CPUs from the
intel_idle and RAPL drivers (Andy Shevchenko).
- Update the tasks freezer to list tasks that refused to freeze
and caused a system transition to a sleep state to be aborted
(Todd Brandt).
- Update the pm-graph set of tools to v5.2 (Todd Brandt).
- Fix some issues in the cpupower utility (Anders Roxell, Prarit
Bhargava).

Pull power management updates from Rafael Wysocki:
"These make hibernation on 32-bit x86 systems work in all of the cases
in which it works on 64-bit x86 ones, update the menu cpuidle governor
and the "polling" state to make them more efficient, add more hardware
support to cpufreq drivers and fix issues with some of them, fix a bug
in the conservative cpufreq governor, fix the operating performance
points (OPP) framework and make it more stable, update the devfreq
subsystem to take changes in the APIs used by into account and clean
up some things all over.
Specifics:
- Backport hibernation bug fixes from x86-64 to x86-32 and
consolidate hibernation handling on x86 to allow 32-bit systems to
work in all of the cases in which 64-bit ones work (Zhimin Gu, Chen
Yu).
- Fix hibernation documentation (Vladimir D. Seleznev).
- Update the menu cpuidle governor to fix a couple of issues with it,
make it more efficient in some cases and clean it up (Rafael
Wysocki).
- Rework the cpuidle polling state implementation to make it more
efficient (Rafael Wysocki).
- Clean up the cpuidle core somewhat (Fieah Lim).
- Fix the cpufreq conservative governor to take policy limits into
account properly in some cases (Rafael Wysocki).
- Add support for retrieving guaranteed performance information to
the ACPI CPPC library and make the intel_pstate driver use it to
expose the CPU base frequency via sysfs on systems with the
hardware-managed P-states (HWP) feature enabled (Srinivas
Pandruvada).
- Fix clang warning in the CPPC cpufreq driver (Nathan Chancellor).
- Get rid of device_node.name printing from cpufreq (Rob Herring).
- Remove unnecessary unlikely() from the cpufreq core (Igor Stoppa).
- Add support for the r8a7744 SoC to the cpufreq-dt driver (Biju
Das).
- Update the dt-platdev cpufreq driver to allow RK3399 to have
separate tunables per cluster (Dmitry Torokhov).
- Fix the dma_alloc_coherent() usage in the tegra186 cpufreq driver
(Christoph Hellwig).
- Make the imx6q cpufreq driver read OCOTP through nvmem for
imx6ul/imx6ull (Anson Huang).
- Fix several bugs in the operating performance points (OPP)
framework and make it more stable (Viresh Kumar, Dave Gerlach).
- Update the devfreq subsystem to take changes in the APIs used by
into account, fix some issues with it and make it stop print
device_node.name directly (Bjorn Andersson, Enric Balletbo i Serra,
Matthias Kaehlcke, Rob Herring, Vincent Donnefort, zhong jiang).
- Prepare the generic power domains (genpd) framework for dealing
with domains containing CPUs (Ulf Hansson).
- Prevent sysfs attributes representing low-power S0 residency
counters from being exposed if low-power S0 support is not
indicated in ACPI FADT (Rajneesh Bhardwaj).
- Get rid of custom CPU features macros for Intel CPUs from the
intel_idle and RAPL drivers (Andy Shevchenko).
- Update the tasks freezer to list tasks that refused to freeze and
caused a system transition to a sleep state to be aborted (Todd
Brandt).
- Update the pm-graph set of tools to v5.2 (Todd Brandt).
- Fix some issues in the cpupower utility (Anders Roxell, Prarit
Bhargava)"

usb: gadget: uvc: configfs: Add bFrameIndex attributes
- Add bFrameIndex as a UVCG_FRAME_ATTR_RO for each frame size. - Automatically assign ascending bFrameIndex to each frame in a format. Before all "bFrameindex" attributes were set to "1" with no way to configure the gadget otherwise. This resulted in the host always negotiating for bFrameIndex 1 (i.e. the first frame size of the gadget). After the negotiation the host driver will set the user or application selected frame size, while the gadget is actually set to the first frame size. Now, when the containing format is linked into the streaming header, iterate over all child frame descriptors and assign ascending indices. The automatically assigned indices can be read from the new read only bFrameIndex configfs attribute in each frame descriptor item.

usb: gadget: uvc: configfs: Add bFormatIndex attributes
The UVC format description are numbered using the descriptor's bFormatIndex field. The index is used in UVC requests, and is thus needed to handle requests in userspace. Make it dynamically discoverable by exposing it in a bFormatIndex configfs attribute of the uncompressed and mjpeg format config items. The bFormatIndex value exposed through the attribute is stored in the config item private data. However, that value is never set: the driver instead computes the bFormatIndex value when linking the stream class header in the configfs hierarchy and stores it directly in the class descriptors in a separate structure. In order to expose the value through the configfs attribute, store it in the config item private data as well. This results in a small code simplification.

1st round of IIO new device support, features and cleanups in the 4.20 cycle.
There is a merge commit in here to pull in regmap support for repeatedly
reading the same register (to read out FIFOs). Used by the adxl372 driver.
This will find uses elsewhere once we tidy up various drivers that are
effectively doing this and relying on not enabling regcache.
New device support
* Analog devices ADXL372 accelerometer
- new driver for this accelerometer including fifo and and interrupt support.
Follow up patches enforce trigger validation, add sampling frequency
control and filter bandwidth control. A later series added i2c support
to the existing SPI support.
* ST lsm6dsx
- rework and add support fo the LSM6DSO 6 axis mems sensor.
* Linear LTC 1660 DAC
- new driver supporting the LTC 1660 and LTC 1665 SPI DACs.
* Microchip mcp3911 ADC.
- new driver for this integrated analog front end and ADC.
* Qualcomm SPMI PMIC5 adc driver
- using the spmi framework, new driver and bindings for this ADC.
Follow up patch adds some missing channels.
Features
* ad5758
- support hard reset using a gpio (if provided).
* mpu6050
- Regulator support
* qcom-spmi-adc5
- Sanity check the channel numbers provided by DT to make sure the
driver actually knows about them.
* sc27xx
- give raw data for channel 20 as it's used on all known boards for
the headset which needs a custom converstion function. If it turns
out someone builds a board where this isn't true we will deal with it
when it happens.
- add ADC scale calibration.
* tsl2772
- support device tree binding to set the proximity led settings.
- regulator supprot.
- binding for apds9930 - trivial addition as register compatible with tsl2772.
Cleanups / Minor fixes
* adxl345
- supress a static checker warning but explicitly checking if the id
object is null.
* bh1750
- avoid CONFIG_PM_SLEEP checks.
- SPDX.
* bme680
- spelling mistake
- use clamp rather than open coding.
- white space and other similar fixes.
- rename MSK to MASK for clarifty and use GENMASK to specify them.
- use the FIELD_GET macro rather than a very odd accessor of dividing by
16 to get the shift.
- rework to share handing for oversampling of the various channels in a
unified way.
- check explicitly for val2 in write_raw function to ensure it is 0.
- drop some field defines that don't add anything.
* dpot-adc
- SPDX
* envelope detector
- SPDX
* isl29501
- fix an ancient compiler warning mostly because it results in much
nicer code.
* max30102
- mark switch fall throughs.

vmbus: add driver_override support
Add support for overriding the default driver for a VMBus device in the same way that it can be done for PCI devices. This patch adds the /sys/bus/vmbus/devices/.../driver_override file and the logic for matching. This is used by driverctl tool to do driver override. https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitlab.com%2Fdriverctl%2Fdriverctl&data=02%7C01%7Ckys%40microsoft.com%7C42e803feb2c544ef6ea908d5fd538878%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636693457619960040&sdata=kEyYHRIjNZCk%2B37moCSqbrZL426YccNQrsWpENcrZdw%3D&reserved=0 Signed-off-by: Stephen Hemminger <sthemmin@microsoft.com> Signed-off-by: K.

PM / hibernate: Documentation: fix image_size default value
This commit updates the default value of /sys/power/image_size in the documentation. Since ac5c24ec1e983313ef0015258fba6f630e54e7cn the `image_size' value is set to about 2/5 of RAM, according to kernel/power/snapshot.c: image_size = ((totalram_pages * 2) / 5) * PAGE_SIZE; but this change was not reflected everywhere in the documentation.

There is no way for user-space to know what a given DSA network device's tagging protocol is. Expose this information through a dsa/tagging attribute which reflects the tagging protocol currently in use.

xen/blkback: don't keep persistent grants too long
Persistent grants are allocated until a threshold per ring is being reached. Those grants won't be freed until the ring is being destroyed meaning there will be resources kept busy which might no longer be used. Instead of freeing only persistent grants until the threshold is reached add a timestamp and remove all persistent grants not having been in use for a minute.

f2fs-for-4.19-rc1
In this round, we've tuned f2fs to improve general performance by serializing
block allocation and enhancing discard flows like fstrim which avoids user IO
contention. And we've added fsync_mode=nobarrier which gives an option to user
where it skips issuing cache_flush commands to underlying flash storage. And
there are many bug fixes related to fuzzed images, revoked atomic writes, quota
ops, and minor direct IO.
Enhancement:
- add fsync_mode=nobarrier which bypasses cache_flush command
- enhance the discarding flow which avoids user IOs and issues in LBA order
- readahead some encrypted blocks during GC
- enable in-memory inode checksum to verify the blocks if F2FS_CHECK_FS is set
- enhance nat_bits behavior
- set -o discard by default
- set REQ_RAHEAD to bio in ->readpages
Bug fixes:
- fix a corner case to corrupt atomic_writes revoking flow
- revisit i_gc_rwsem to fix race conditions
- fix some dio behaviors captured by xfstests
- correct handling errors given by quota-related failures
- add many sanity check flows to avoid fuzz test failures
- add more error number propagation to their callers
- fix several corner cases to continue fault injection w/ shutdown loop

Char/Misc driver patches for 4.19-rc1
Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level
hardware bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of
the crazy out-of-tree drivers that have been floating around
for years, combined with some really hacky userspace
implementations. This is only for GNSS receivers, but you
have to start somewhere, and this is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and existing
drivers.
Full details of everything is in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

Staging/IIO patches for 4.19-rc1
Here are the big staging/iio patches for 4.19-rc1. Lots of churn here, with tons of cleanups happening in staging drivers, a removal of an old crypto driver that no one was using (skein), and the addition of some new IIO drivers. Also added was a "gasket" driver from Google that needs loads of work and the erofs filesystem. Even with adding all of the new drivers and a new filesystem, we are only adding about 1000 lines overall to the kernel linecount, which shows just how much cleanup happened, and how big the unused crypto driver was. All of these have been in the linux-next tree for a while now with no reported issues. Note, you will have a merge problem with a device tree IIO file and the MAINTAINERS file, both resolutions are easy, just take all changed.

powerpc updates for 4.19
Notable changes:
- A fix for a bug in our page table fragment allocator, where a page table page
could be freed and reallocated for something else while still in use, leading
to memory corruption etc. The fix reuses pt_mm in struct page (x86 only) for
a powerpc only refcount.
- Fixes to our pkey support. Several are user-visible changes, but bring us in
to line with x86 behaviour and/or fix outright bugs. Thanks to Florian Weimer
for reporting many of these.
- A series to improve the hvc driver & related OPAL console code, which have
been seen to cause hardlockups at times. The hvc driver changes in particular
have been in linux-next for ~month.
- Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y.
- Remove Power8 DD1 and Power9 DD1 support, neither chip should be in use
anywhere other than as a paper weight.
- An optimised memcmp implementation using Power7-or-later VMX instructions
- Support for barrier_nospec on some NXP CPUs.
- Support for flushing the count cache on context switch on some IBM CPUs
(controlled by firmware), as a Spectre v2 mitigation.
- A series to enhance the information we print on unhandled signals to bring it
into line with other arches, including showing the offending VMA and dumping
the instructions around the fault.

Merge tag 'powerpc-4.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
"Notable changes:
- A fix for a bug in our page table fragment allocator, where a page
table page could be freed and reallocated for something else while
still in use, leading to memory corruption etc. The fix reuses
pt_mm in struct page (x86 only) for a powerpc only refcount.
- Fixes to our pkey support. Several are user-visible changes, but
bring us in to line with x86 behaviour and/or fix outright bugs.
Thanks to Florian Weimer for reporting many of these.
- A series to improve the hvc driver & related OPAL console code,
which have been seen to cause hardlockups at times. The hvc driver
changes in particular have been in linux-next for ~month.
- Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y.
- Remove Power8 DD1 and Power9 DD1 support, neither chip should be in
use anywhere other than as a paper weight.
- An optimised memcmp implementation using Power7-or-later VMX
instructions
- Support for barrier_nospec on some NXP CPUs.
- Support for flushing the count cache on context switch on some IBM
CPUs (controlled by firmware), as a Spectre v2 mitigation.
- A series to enhance the information we print on unhandled signals
to bring it into line with other arches, including showing the
offending VMA and dumping the instructions around the fault.

regulator: Changes for v4.19
The biggest set of changes in here is the addition of the Qualcomm RPMH
driver. As well as the regualtor driver itself being quite large due to
the usual involved Qualcomm regulator stuff there's also some code
shared with the arm-soc tree, a bus driver required to communicate with
the hardware that actually winds up being much larger than the regulator
driver itself and a LLCC driver that was part of the same signed tag
used with the arm-soc tree.
Other than that it's a fairly standard and quiet release, highlights
include:
- Addition of device links from regulator consumers to their
regulators, helping the core avoid dependency issues during suspend.
- Support for the entertainingly innovative suspend implementation in
the BD9571MWV.
- Support for switch regulators on the PFUZE100, this required two goes
due to backwards compatibility issues with old DTs that were
discovered.
- Support for Freescale PFUZE3001 and SocioNext UniPhier.
- The aforementioned Qualcomm RPMH driver together with the driver
changes required to support it.

Not a big pull request with only 37 non-merge commits, most of which are touching dwc2 (74% of the changes). The most important changes are dwc2's support for uframe scheduling and its endian-agnostic readl/writel wrappers. From dwc3 side we have a special new glue layer for Synopsys HAPS which will help Synopsys running FPGA validation using our upstream driver. We also have the beginnings of dual-role support for Intel Merrifield platform. Apart from these, just a series of non-critical changes. -----BEGIN PGP SIGNATURE----- iQJRBAABCgA7FiEElLzh7wn96CXwjh2IzL64meEamQYFAltewsEdHGZlbGlwZS5i YWxiaUBsaW51eC5pbnRlbC5jb20ACgkQzL64meEamQaV8BAAziA9QIT6to7Zzd7t tsfU3chXUS2t+fZ6drADdHHwJTvjCT4D9FbpYFSNC9lanSLB+IwQ6rZGglyyPh5P DVcWObi8wR1+w8gcx+NL65XuzM/oM8Sx+zSA+3hV7H8A1ePikd+wFpXcZhY0zoLS 00BoAf66CvRvGAGX8e1HouL4LPs/V5vllxcObKLrzcziCNziLhAy1MkONAwSagvP JA50nh0Jau6p/+inF/931oeixmVvTV0xJjqveIf6cVsyv9jNy+I53rFwVsaiSVLz dvzrnPmzWbT4F1yuLgqXccd68FF4Zm+Vl+uHyzaZ7b8e1JK7ABg9a7Us6CjP9HXq aw63hUKmrsTsTyLCWkoU6ypeCYJF3Et49pzicLRFOdXufWJLTRa0iNbgyf8gNOQt K8igJZkmHnb4RByLITtHot3Qdpn2Mr+8Cu/H4TpqQBAKom6mxdwkfm4lojBzLoRn IIr81yTJD00uqgQ40IeoFyV5zz4CqMti3GQX8QXO2wdbrKlaLCr4UDuu4llE2AJ9 1cYV8SMoC2yXaGsshe2dvCq4/lhxiOXPBNoR/GvtvXd84AXaYCsuphUhSGTybYLG a3LO72mn4R8hAnqzh3+xyC4Irs9hgVJUKOD7fFn0ZPvCXgLUQIYRimIprEQ0EsCI /lcdOwOheSGM9Fq5U/fcWDdZcmE= =HiNz -----END PGP SIGNATURE----- Merge tag 'usb-for-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: changes for v4.19 Not a big pull request with only 37 non-merge commits, most of which are touching dwc2 (74% of the changes).

x86/bugs, kvm: Introduce boot-time control of L1TF mitigations
Introduce the 'l1tf=' kernel command line option to allow for boot-time
switching of mitigation that is used on processors affected by L1TF.
The possible values are:
full
Provides all available mitigations for the L1TF vulnerability. Disables
SMT and enables all mitigations in the hypervisors. SMT control via
/sys/devices/system/cpu/smt/control is still possible after boot.
Hypervisors will issue a warning when the first VM is started in
a potentially insecure configuration, i.e. SMT enabled or L1D flush
disabled.
full,force
Same as 'full', but disables SMT control. Implies the 'nosmt=force'
command line option. sysfs control of SMT and the hypervisor flush
control is disabled.
flush
Leaves SMT enabled and enables the conditional hypervisor mitigation.
Hypervisors will issue a warning when the first VM is started in a
potentially insecure configuration, i.e. SMT enabled or L1D flush
disabled.
flush,nosmt
Disables SMT and enables the conditional hypervisor mitigation. SMT
control via /sys/devices/system/cpu/smt/control is still possible
after boot. If SMT is reenabled or flushing disabled at runtime
hypervisors will issue a warning.
flush,nowarn
Same as 'flush', but hypervisors will not warn when
a VM is started in a potentially insecure configuration.
off
Disables hypervisor mitigations and doesn't emit any warnings.
Default is 'flush'.
Let KVM adhere to these semantics, which means:
- 'lt1f=full,force' : Performe L1D flushes. No runtime control
possible.
- 'l1tf=full'
- 'l1tf-flush'
- 'l1tf=flush,nosmt' : Perform L1D flushes and warn on VM start if
SMT has been runtime enabled or L1D flushing
has been run-time enabled
- 'l1tf=flush,nowarn' : Perform L1D flushes and no warnings are emitted.
- 'l1tf=off' : L1D flushes are not performed and no warnings
are emitted.
KVM can always override the L1D flushing behavior using its 'vmentry_l1d_flush'
module parameter except when lt1f=full,force is set.
This makes KVM's private 'nosmt' option redundant, and as it is a bit
non-systematic anyway (this is something to control globally, not on
hypervisor level), remove that option.
Add the missing Documentation entry for the l1tf vulnerability sysfs file
while at it.

First set of IIO new device support, features and cleanups in the 4.19 cycle
The usual mixed bunch. Particular good to see is the generic
touch screen driver. Will be interesting to see if this works
for other ADCs without major changes.
Core features
* Channel types
- New position relative channel type primarily for touch screen
sensors to feed the generic touchscreen driver.
New device support
* ad5586
- Add support for the AD5311R DAC.
* Generic touch screen driver as an IIO consumer.
- Note this is in input, but due to dependencies is coming through
the IIO tree.
- Specific support for this added to the at91-sama5d2 ADC.
- Various necessary DT bindings added.
Staging Drops
* ADIS16060 gyro
- A device with a very odd interface that was never cleanly supported.
It's now very difficult to get, so unlikely it'll ever be fixed up.
Cleanups and minor features and fixes
* core
- Fix y2038 timestamp issues now the core support is in place.
* 104-quad-8
- Provide some defines for magic numbers to help readability.
- Fix an off by one error in register selection
* ad7606
- Put in a missing function parameter name in a prototype.
* adis16023
- Use generic sign_extend function rather than local version.
* adis16240
- Use generic sign_extend funciton rather than local version.
* at91-sama5d2
- Drop dependency on HAS_DMA now this is handled elsewhere. Will
improve build test coverage.
- Add oversampling ratio control. Note there is a minor ABI change
here to increase the apparent depth to 14 bits so as to allow
for transparent provision of different oversampling ratios that
drop the actual bit depth to 13 or 12 bits.
* hx711
- Add a MAINTAINERS entry for this device.
* inv_mpu6050
- Replace the timestamp fifo 'special' code with generic timestamp
handling.
- Switch to using local store of timestamp divider rather than rate
as that is more helpful for accurate time measurement.
- Fix an unaligned access that didn't seem to be causing any trouble.
- Use the fifo overflow bit to track the overflow status rather than
a software counter.
- New timestamping mechanism to deal with missed sample interrupts.
* stm32-adc
- Drop HAS_DMA build dependency.
* sun4i-gpadc
- Select REGMAP_IRQ a very rarely hit build issue fix.

cpu/hotplug: Provide knobs to control SMT
Provide a command line and a sysfs knob to control SMT. The command line options are: 'nosmt': Enumerate secondary threads, but do not online them 'nosmt=force': Ignore secondary threads completely during enumeration via MP table and ACPI/MADT. The sysfs control file has the following states (read/write): 'on': SMT is enabled. Secondary threads can be freely onlined 'off': SMT is disabled. Secondary threads, even if enumerated cannot be onlined 'forceoff': SMT is permanentely disabled. Writes to the control file are rejected. 'notsupported': SMT is not supported by the CPU The command line option 'nosmt' sets the sysfs control to 'off'. This can be changed to 'on' to reenable SMT during runtime. The command line option 'nosmt=force' sets the sysfs control to 'forceoff'. This cannot be changed during runtime. When SMT is 'on' and the control file is changed to 'off' then all online secondary threads are offlined and attempts to online a secondary thread later on are rejected. When SMT is 'off' and the control file is changed to 'on' then secondary threads can be onlined again. The 'off' -> 'on' transition does not automatically online the secondary threads. When the control file is set to 'forceoff', the behaviour is the same as setting it to 'off', but the operation is irreversible and later writes to the control file are rejected. When the control status is 'notsupported' then writes to the control file are rejected.

f2fs-for-4.18-rc1
In this round, we've mainly focused on discard, aka unmap, control along with fstrim for Android-specific usage model. In addition, we've fixed writepage flow which returned EAGAIN previously resulting in EIO of fsync(2) due to mapping's error state. In order to avoid old MM bug [1], we decided not to use __GFP_ZERO for the mapping for node and meta page caches. As always, we've cleaned up many places for future fsverity and symbol conflicts. Enhancement: - do discard/fstrim in lower priority considering fs utilization - split large discard commands into smaller ones for better responsiveness - add more sanity checks to address syzbot reports - add a mount option, fsync_mode=nobarrier, which can reduce # of cache flushes - clean up symbol namespace with modified function names - be strict on block allocation and IO control in corner cases Bug fix: - don't use __GFP_ZERO for mappings - fix error reports in writepage to avoid fsync() failure - avoid selinux denial on CAP_RESOURCE on resgid/resuid - fix some subtle race conditions in GC/atomic writes/shutdown - fix overflow bugs in sanity_check_raw_super - fix missing bits on get_flags Clean-up: - prepare the generic flow for future fsverity integration - fix some broken coding standard [1] https://lkml.org/lkml/2018/4/8/661 -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAlsepb8ACgkQQBSofoJI UNJdSw/+IhrYJFkJEN/pV4M5xSjYirl/P2WJ4AGi6HcpjEGmaDiBi2whod1Jw2NE 1auSMiby7K91VAmPvxMmmLhOdC8XgJ8jwY1nEaZMfmMXohlaD3FDY5bzYf5rJDF4 J184P6xUZ2IKlFVA4prwNQgYi3awPthVu1lxbFPp8GUHDbmr5ZXEysxPDzz2O0Em oE7WmklmyCHJPhmg/EcVXfF/Ekf3zMOVR+EI2otcDjnWIQioVetIK8CKi0MM4bkG X8Z318ANjGTd42woupXIzsiTrMRONY7zzkUvE+S6tfUjKZoIdofDM5OIXMdOxpxL DZ53WrwfeB74igD8jDZgqD6OaonIfDfCuKrwUASFAC2Ou4h3apj3ckUzoHtAhEUL z5yTSKTrtfuoSufhBp+nKKs3ijDgms76arw8x/pPdN6D6xDwIJtBPxC2sObPaj35 damv4GyM4+sbhGO/Gbie2q6za55IvYFZc7JNCC2D2K5tnBmUaa7/XdvxcyigniGk AZgkaddHePkAZpa5AYYirZR8bd7IFds0+m6VcybG0/pYb0qPEcI6U4mujBSCIwVy kXuD7su3jNjj6hWnCl5PSQo8yBWS5H8c6/o+5XHozzYA91dsLAmD8entuCreg6Hp NaIFio0qKULweLK86f66qQTsRPMpYRAtqPS0Ew0+3llKMcrlRp4= =JrW7 -----END PGP SIGNATURE----- Merge tag 'f2fs-for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've mainly focused on discard, aka unmap, control along with fstrim for Android-specific usage model.

iio: Add channel for Position Relative
Add new channel type for relative position on a pad. These type of analog sensor offers the position of a pen on a touchpad, and is represented as a voltage, which can be converted to a position on X and Y axis on the pad. The channel will hand the relative position on the pad in both directions. The channel can then be consumed by a touchscreen driver or read as-is for a raw indication of the touchpen on a touchpad.

Staging/IIO patches for 4.18-rc1
Here is the big staging and IIO driver update for 4.18-rc1.
It was delayed as I wanted to make sure the final driver deletions did
not cause any major merge issues, and all now looks good.
There are a lot of patches here, just over 1000. The diffstat summary
shows the major changes here:
1007 files changed, 16828 insertions(+), 227770 deletions(-)
Because of this, we might be close to shrinking the overall kernel
source code size for two releases in a row.
There was loads of work in this release cycle, primarily:
- tons of ks7010 driver cleanups
- lots of mt7621 driver fixes and cleanups
- most driver cleanups
- wilc1000 fixes and cleanups
- lots and lots of IIO driver cleanups and new additions
- debugfs cleanups for all staging drivers
- lots of other staging driver cleanups and fixes, the shortlog
has the full details.
but the big user-visable things here are the removal of 3 chunks of
code:
- ncpfs and ipx were removed on schedule, no one has cared about
this code since it moved to staging last year, and if it needs
to come back, it can be reverted.
- lustre file system is removed. I've ranted at the lustre
developers about once a year for the past 5 years, with no
real forward progress at all to clean things up and get the
code into the "real" part of the kernel. Given that the
lustre developers continue to work on an external tree and try
to port those changes to the in-kernel tree every once in a
while, this whole thing really really is not working out at
all. So I'm deleting it so that the developers can spend the
time working in their out-of-tree location and get things
cleaned up properly to get merged into the tree correctly at a
later date.
Because of these file removals, you will have merge issues on some of
these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
atomisp driver). Just delete those files, it's a simple merge :)
All of this has been in linux-next for a while with no reported
problems.

libnvdimm for 4.18
* DAX broke a fundamental assumption of truncate of file mapped pages.
The truncate path assumed that it is safe to disconnect a pinned page
from a file and let the filesystem reclaim the physical block. With DAX
the page is equivalent to the filesystem block. Introduce
dax_layout_busy_page() to enable filesystems to wait for pinned DAX
pages to be released. Without this wait a filesystem could allocate
blocks under active device-DMA to a new file.
* DAX arranges for the block layer to be bypassed and uses
dax_direct_access() + copy_to_iter() to satisfy read(2) calls.
However, the memcpy_mcsafe() facility is available through the pmem
block driver. In order to safely handle media errors, via the DAX
block-layer bypass, introduce copy_to_iter_mcsafe().
* Fix cache management policy relative to the ACPI NFIT Platform
Capabilities Structure to properly elide cache flushes when they are not
necessary. The table indicates whether CPU caches are power-fail
protected. Clarify that a deep flush is always performed on
REQ_{FUA,PREFLUSH} requests.

powerpc updates for 4.18
Notable changes:
- Support for split PMD page table lock on 64-bit Book3S (Power8/9).
- Add support for HAVE_RELIABLE_STACKTRACE, so we properly support live
patching again.
- Add support for patching barrier_nospec in copy_from_user() and syscall entry.
- A couple of fixes for our data breakpoints on Book3S.
- A series from Nick optimising TLB/mm handling with the Radix MMU.
- Numerous small cleanups to squash sparse/gcc warnings from Mathieu Malaterre.
- Several series optimising various parts of the 32-bit code from Christophe Leroy.
- Removal of support for two old machines, "SBC834xE" and "C2K" ("GEFanuc,C2K"),
which is why the diffstat has so many deletions.
And many other small improvements & fixes.
There's a few out-of-area changes. Some minor ftrace changes OK'ed by Steve, and
a fix to our powernv cpuidle driver. Then there's a series touching mm, x86 and
fs/proc/task_mmu.c, which cleans up some details around pkey support. It was
ack'ed/reviewed by Ingo & Dave and has been in next for several weeks.

acpi, nfit: Remove ecc_unit_size
The "Clear Error Unit" may be smaller than the ECC unit size on some devices. For example, poison may be tracked at 64-byte alignment even though the ECC unit is larger. Unless / until the ACPI specification provides a non-ambiguous way to communicate this property do not expose this to userspace. Software that had been using this property must already be prepared for the case where the property is not provided on older kernels, so it is safe to remove this attribute.

cxl: Disable prefault_mode in Radix mode
Currently we see a kernel-oops reported on Power-9 while attaching a
context to an AFU, with radix-mode and sysfs attr 'prefault_mode' set
to anything other than 'none'. The backtrace of the oops is of this
form:
Unable to handle kernel paging request for data at address 0x00000080
Faulting instruction address: 0xc00800000bcf3b20
cpu 0x1: Vector: 300 (Data Access) at [c00000037f003800]

system_call+0x58/0x6c
The issue is caused as on Power-8 the AFU attr 'prefault_mode' was
used to improve initial storage fault performance by prefaulting
process segments. However on Power-9 with radix mode we don't have
Storage-Segments that we can prefault. Also prefaulting process Pages
will be too costly and fine-grained.
Hence, since the prefaulting mechanism doesn't makes sense of
radix-mode, this patch updates prefault_mode_store() to not allow any
other value apart from CXL_PREFAULT_NONE when radix mode is enabled.

usb: hub: Per-port setting to use old enumeration scheme
The "old" enumeration scheme is considerably faster (it takes ~244ms instead of ~356ms to get the descriptor). It is currently only possible to use the old scheme globally (/sys/module/usbcore/parameters/old_scheme_first), which is not desirable as the new scheme was introduced to increase compatibility with more devices. However, in our case, we care about time-to-active for a specific USB device (which we make the firmware for), on a specific port (that is pogo-pin based: not a standard USB port). This new sysfs option makes it possible to use the old scheme on a single port only.

ima: define a new policy condition based on the filesystem name
If/when file data signatures are distributed with the file data, this patch will not be needed. In the current environment where only some files are signed, the ability to differentiate between file systems is needed. Some file systems consider the file system magic number internal to the file system. This patch defines a new IMA policy condition named "fsname", based on the superblock's file_system_type (sb->s_type) name. This allows policy rules to be expressed in terms of the filesystem name. The following sample rules require file signatures on rootfs files executed or mmap'ed. appraise func=BPRM_CHECK fsname=rootfs appraise_type=imasig appraise func=FILE_MMAP fsname=rootfs appraise_type=imasig Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com> Cc: Dave Chinner <david@fromorbit.com> Cc: Theodore Ts'o <tytso@mit.edu> |

Merge branch 'speck-v20' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Merge speculative store buffer bypass fixes from Thomas Gleixner:
- rework of the SPEC_CTRL MSR management to accomodate the new fancy
SSBD (Speculative Store Bypass Disable) bit handling.
- the CPU bug and sysfs infrastructure for the exciting new Speculative
Store Bypass 'feature'.
- support for disabling SSB via LS_CFG MSR on AMD CPUs including
Hyperthread synchronization on ZEN.
- PRCTL support for dynamic runtime control of SSB
- SECCOMP integration to automatically disable SSB for sandboxed
processes with a filter flag for opt-out.
- KVM integration to allow guests fiddling with SSBD including the new
software MSR VIRT_SPEC_CTRL to handle the LS_CFG based oddities on
AMD.
- BPF protection against SSB
.. this is just the core and x86 side, other architecture support will
come separately.

EVM: Allow runtime modification of the set of verified xattrs
Sites may wish to provide additional metadata alongside files in order to make more fine-grained security decisions[1]. The security of this is enhanced if this metadata is protected, something that EVM makes possible. However, the kernel cannot know about the set of extended attributes that local admins may wish to protect, and hardcoding this policy in the kernel makes it difficult to change over time and less convenient for distributions to enable. This patch adds a new /sys/kernel/security/integrity/evm/evm_xattrs node, which can be read to obtain the current set of EVM-protected extended attributes or written to in order to add new entries. Extending this list will not change the validity of any existing signatures provided that the file in question does not have any of the additional extended attributes - missing xattrs are skipped when calculating the EVM hash. [1] For instance, a package manager could install information about the package uploader in an additional extended attribute. Local LSM policy could then be associated with that extended attribute in order to restrict the privileges available to packages from less trusted uploaders.

1st round of IIO new device support, features and cleanup for the 4.18 cycle
A nice mix this time of excellent cleanups (many to send drivers
speeding toward staging graduations) and new drivers / device support.
A good part of this is Brian Masney's never ending task on the tsl2x7x
driver. The end is in sight so hopefully we'll get that one out of
staging very soon!
New device support
* AD5686
- Support AD5685R (was wrongly present as AD5685)
- Support AD5672R, AD5676, AD5676, AD5684R and AD5686R 4 and 8 channel
SPI DACs with various precisions.
- Support AD5671R, AD5675R, AD5694, AD5694R, AD5695R, AD5696 and AD5696R
I2C DACs with various percisions and numbers of channels.
* Analog front end rescale driver - New driver.
- Support current sensing usings a shunt resistor.
- Support simple voltage dividers.
- support simple current sense amplifiers.
* TI dac5571
- New driver and device bindings supporting:

rpmsg: Add driver_override device attribute for rpmsg_device
This patch adds "driver_override" device attribute for rpmsg_device which will allow users to explicitly specify the rpmsg_driver to be used via sysfs entry. The "driver_override" device attribute implemented here is very similar to "driver_override" implemented for platform, pci, and amba bus types. One important use-case of "driver_override" device attribute is to force use of rpmsg_chrdev driver for certain rpmsg_device instances.

power: supply: Add 'usb_type' property and supporting code
This commit adds the 'usb_type' property to represent USB supplies which can report a number of different types based on a connection event. Examples of this already exist in drivers whereby the existing 'type' property is updated, based on an event, to represent what was connected (e.g. USB, USB_DCP, USB_ACA, ...). Current implementations however don't show all supported connectable types, so this knowledge has to be exlicitly known for each driver that supports this. The 'usb_type' property is intended to fill this void and show users all possible USB types supported by a driver. The property, when read, shows all available types for the driver, and the one currently chosen is highlighted/bracketed. It is expected that the 'type' property would then just show the top-level type 'USB', and this would be static. Currently the 'usb_type' enum contains all of the USB variant types that exist for the 'type' enum at this time, and in addition has SDP and PPS types. The mirroring is intentional so as to not impact existing usage of the 'type' property.

There are no contents changes in the documentation, except few spelling fixes. The relatively large diffstat stems from the indentation and paragraph wrapping changes. I've tried to keep the formatting as consistent as possible, but I could miss some places that needed markup and add some markup where it was not necessary.

Char/Misc patches for 4.17-rc1
Here is the big set of char/misc driver patches for 4.17-rc1.
There are a lot of little things in here, nothing huge, but all
important to the different hardware types involved:
- thunderbolt driver updates
- parport updates (people still care...)
- nvmem driver updates
- mei updates (as always)
- hwtracing driver updates
- hyperv driver updates
- extcon driver updates
- and a handfull of even smaller driver subsystem and individual
driver updates
All of these have been in linux-next with no reported issues.

Staging/IIO patches for 4.17-rc1
Here is the big set of Staging/IIO driver patches for 4.17-rc1. It is a lot, over 500 changes, but not huge by previous kernel release standards. We deleted more lines than we added again (27k added vs. 91k remvoed), thanks to finally being able to delete the IRDA drivers and networking code. We also deleted the ccree crypto driver, but that's coming back in through the crypto tree to you, in a much cleaned-up form. Added this round is at lot of "mt7621" device support, which is for an embedded device that Neil Brown cares about, and of course a handful of new IIO drivers as well. And finally, the fsl-mc core code moved out of the staging tree to the "real" part of the kernel, which is nice to see happen as well.

PM: cpuidle/suspend: Add s2idle usage and time state attributes
Add a new attribute group called "s2idle" under the sysfs directory of each cpuidle state that supports the ->enter_s2idle callback and put two new attributes, "usage" and "time", into that group to represent the number of times the given state was requested for suspend-to-idle and the total time spent in suspend-to-idle after requesting that state, respectively. That will allow diagnostic information related to suspend-to-idle to be collected without enabling advanced debug features and analyzing dmesg output. Signed-off-by: Rafael J.

IMA: Support using new creds in appraisal policy
The existing BPRM_CHECK functionality in IMA validates against the credentials of the existing process, not any new credentials that the child process may transition to. Add an additional CREDS_CHECK target and refactor IMA to pass the appropriate creds structure. In ima_bprm_check(), check with both the existing process credentials and the credentials that will be committed when the new process is started. This will not change behaviour unless the system policy is extended to include CREDS_CHECK targets - BPRM_CHECK will continue to check the same credentials that it did previously. After this patch, an IMA policy rule along the lines of: measure func=CREDS_CHECK subj_type=unconfined_t will trigger if a process is executed and runs as unconfined_t, ignoring the context of the parent process. This is in contrast to: measure func=BPRM_CHECK subj_type=unconfined_t which will trigger if the process that calls exec() is already executing in unconfined_t, ignoring the context that the child process executes into.

usb: common: Small class for USB role switches
USB role switch is a device that can be used to choose the data role for USB connector. With dual-role capable USB controllers, the controller itself will be the switch, but on some platforms the USB host and device controllers are separate IPs and there is a mux between them and the connector. On those platforms the mux driver will need to register the switch. With USB Type-C connectors, the host-to-device relationship is negotiated over the Configuration Channel (CC). That means the USB Type-C drivers need to be in control of the role switch. The class provides a simple API for the USB Type-C drivers for the control. For other types of USB connectors (mainly microAB) the class provides user space control via sysfs attribute file that can be used to request role swapping from the switch.

usb: core: introduce per-port over-current counters
For some userspace applications information on the number of over-current conditions at specific USB hub ports is relevant. In our case we have a series of USB hardware (using the cp210x driver) which communicates using a proprietary protocol. These devices sometimes trigger an over-current situation on some hubs. In case of such an over-current situation the USB devices offer an interface for reducing the max used power. As these conditions are quite rare and imply performance reductions of the device we don't want to reduce the max power always. Therefore give user-space applications the possibility to react adequately by introducing an over_current_counter in the usb port struct which is exported via sysfs.

scsi: ufs: Add support for Auto-Hibernate Idle Timer
UFS host controllers may support an autonomous power management feature called the Auto-Hibernate Idle Timer. The timer is set to the number of microseconds of idle time before the UFS host controller will autonomously put the link into Hibernate state. That will save power at the expense of increased latency. Any access to the host controller interface registers will automatically put the link out of Hibernate state. So once configured, the feature is transparent to the driver. Expose the Auto-Hibernate Idle Timer value via SysFS to allow users to choose between power efficiency or lower latency. Set a default value of 150 ms. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Stanislav Nijnikov <stanislav.nijnikov@wdc.com> Signed-off-by: Martin K.

ACPI: Add Time and Alarm Device (TAD) driver
Introduce a driver for the ACPI Time and Alarm Device (TAD) based on Section 9.18 of ACPI 6.2. This driver only supports the system wakeup capabilities of the TAD which are mandatory. Support for the RTC capabilities of the TAD will be added to it in the future. This driver is entirely sysfs-based. It provides attributes (under the TAD platform device) to allow user space to manage the AC and DC wakeup timers of the TAD: set and read their values, set and check their expire timer wake policies, check and clear their status and check the capabilities of the TAD reported by AML. The DC timer attributes are only present if the TAD supports a separate DC alarm timer. The wakeup events handling and power management of the TAD is expected to be taken care of by the ACPI PM domain attached to its platform device. Signed-off-by: Rafael J.
