Xen PVH guests receive the address of the RSDP table from Xen. In order
to support booting a Xen PVH guest via Grub2 using the standard x86
boot entry we need a way for Grub2 to pass the RSDP address to the
kernel.
For this purpose expand the struct setup_header to hold the physical
address of the RSDP address. Being zero means it isn't specified and
has to be located the legacy way (searching through low memory or
EBDA).
While documenting the new setup_header layout and protocol version
2.14 add the missing documentation of protocol version 2.13.
There are Grub2 versions in several distros with a downstream patch
violating the boot protocol by writing past the end of setup_header.
This requires another update of the boot protocol to enable the kernel
to distinguish between a specified RSDP address and one filled with
garbage by such a broken Grub2.
From protocol 2.14 on Grub2 will write the version it is supporting
(but never a higher value than found to be supported by the kernel)
ored with 0x8000 to the version field of setup_header. This enables
the kernel to know up to which field Grub2 has written information
to. All fields after that are supposed to be clobbered.

Alexei Starovoitov says:
====================
pull-request: bpf-next 2018-10-08
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) sk_lookup_[tcp|udp] and sk_release helpers from Joe Stringer which allow
BPF programs to perform lookups for sockets in a network namespace. This would
allow programs to determine early on in processing whether the stack is
expecting to receive the packet, and perform some action (eg drop,
forward somewhere) based on this information.
2) per-cpu cgroup local storage from Roman Gushchin.
Per-cpu cgroup local storage is very similar to simple cgroup storage
except all the data is per-cpu. The main goal of per-cpu variant is to
implement super fast counters (e.g. packet counters), which don't require
neither lookups, neither atomic operations in a fast path.
The example of these hybrid counters is in selftests/bpf/netcnt_prog.c
3) allow HW offload of programs with BPF-to-BPF function calls from Quentin Monnet
4) support more than 64-byte key/value in HW offloaded BPF maps from Jakub Kicinski
5) rename of libbpf interfaces from Andrey Ignatov.
libbpf is maturing as a library and should follow good practices in
library design and implementation to play well with other libraries.
This patch set brings consistent naming convention to global symbols.
6) relicense libbpf as LGPL-2.1 OR BSD-2-Clause from Alexei Starovoitov
to let Apache2 projects use libbpf
7) various AF_XDP fixes from Björn and Magnus

This adds a KVM_PPC_NO_HASH flag to the flags field of the
kvm_ppc_smmu_info struct, and arranges for it to be set when
running as a nested hypervisor, as an unambiguous indication
to userspace that HPT guests are not supported. Reporting the
KVM_CAP_PPC_MMU_HASH_V3 capability as false could be taken as
indicating only that the new HPT features in ISA V3.0 are not
supported, leaving it ambiguous whether pre-V3.0 HPT features
are supported.

With this, userspace can enable a KVM-HV guest to run nested guests
under it.
The administrator can control whether any nested guests can be run;
setting the "nested" module parameter to false prevents any guests
becoming nested hypervisors (that is, any attempt to enable the nested
capability on a guest will fail). Guests which are already nested
hypervisors will continue to be so.

This adds a one-reg register identifier which can be used to read and
set the virtual PTCR for the guest. This register identifies the
address and size of the virtual partition table for the guest, which
contains information about the nested guests under this guest.
Migrating this value is the only extra requirement for migrating a
guest which has nested guests (assuming of course that the destination
host supports nested virtualization in the kvm-hv module).

After the cleanups from Baoquan He, make it even more readable:
- Remove the 'bits' area size column: it's pretty pointless and was even
wrong for some of the entries. Given that MB, GB, TB, PT are 10, 20,
30 and 40 bits, a "8 TB" size description makes it obvious that it's
43 bits.
- Introduce an "offset" column:
--------------------------------------------------------------------------------
start addr | offset | end addr | size | VM area description
-----------------|------------|------------------|---------|--------------------
...
ffff880000000000 | -120 TB | ffffc7ffffffffff | 64 TB | direct mapping of all physical memory (page_offset_base),
this is what limits max physical memory supported.
The -120 TB notation makes it obvious where this particular virtual memory
region starts: 120 TB down from the top of the 64-bit virtual memory space.
Especially the layout of the kernel mappings is a *lot* more obvious when
written this way, plus it's much easier to compare it with the size column
and understand/check/validate and modify the kernel's layout in the future.
- Mark the part from where the 47-bit and 56-bit kernel layouts are 100% identical,
this starts at the -512 GB offset and the EFI region.
- Re-shuffle the size desciptions to be continous blocks of sizes, instead of the
often mixed size. I.e. write "0.5 TB" instead of "512 GB" if we are still in
the TB-granular region of the map.
- Make the 47-bit and 56-bit descriptions use the *exact* same layout and wording,
and only differ where there's a material difference. This makes it easy to compare
the two tables side by side by switching between two terminal tabs.
- Plus enhance a lot of other stylistic/typographical details: make the tables
explicitly tabular, add headers, enhance certain entries, etc. etc.
Note that there are some apparent errors in the tables as well, but I'll fix
them in a separate patch to make it easier to review/validate.

In Documentation/x86/x86_64/mm.txt, the description of the x86-64 virtual

- there's a hard to read mixture of 'TB' and 'bits' notation
- the entries sometimes mention a size in the description and sometimes not
- sometimes they list holes by address, sometimes only as an 'unused hole' line
So make it all a coherent, readable, well organized description.

Add internal PCI bridge support for r8a7744 SoC. The Renesas RZ/G1N

Allow the epoch value to be queried on a server connection. This is in the
rxrpc header of every packet for use in routing and is derived from the
client's state. It's also not supposed to change unless the client gets
restarted.
AFS can make use of this information to deduce whether a fileserver has
been restarted because the fileserver makes client calls to the filesystem
driver's cache manager to send notifications (ie. callback breaks) about
conflicting changes from other clients. These convey the fileserver's own
epoch value back to the filesystem.

Allow specifying the physical address size limit for a new
VM via the kvm_type argument for the KVM_CREATE_VM ioctl. This
allows us to finalise the stage2 page table as early as possible
and hence perform the right checks on the memory slots
without complication. The size is encoded as Log2(PA_Size) in
bits[7:0] of the type field. For backward compatibility the
value 0 is reserved and implies 40bits. Also, lift the limit
of the IPA to host limit and allow lower IPA sizes (e.g, 32).
The userspace could check the extension KVM_CAP_ARM_VM_IPA_SIZE
for the availability of this feature. The cap check returns the
maximum limit for the physical address shift supported by the host.

Pull v4.20 RCU changes from Paul E. McKenney:
- Documentation updates, including some good-eye catches from
Joel Fernandes.
- SRCU updates, most notably changes enabling call_srcu() to be
invoked very early in the boot sequence.
- Torture-test updates, including some preliminary work towards
making rcutorture better able to find problems that result in
insufficient grace-period forward progress.
- Consolidate the RCU-bh, RCU-preempt, and RCU-sched flavors into
a single flavor similar to RCU-sched in !PREEMPT kernels and
into a single flavor similar to RCU-preempt (but also waiting
on preempt-disabled sequences of code) in PREEMPT kernels. This
branch also includes a refactoring of rcu_{nmi,irq}_{enter,exit}()
from Byungchul Park.
- Now that there is only one RCU flavor in any given running kernel,
the many "rsp" pointers are no longer required, and this cleanup
series removes them.
- This branch carries out additional cleanups made possible by
the RCU flavor consolidation, including inlining how-trivial
functions, updating comments and definitions, and removing
now-unneeded rcutorture scenarios.
- Initial changes to RCU to better promote forward progress of
grace periods, including fixing a bug found by Marius Hillenbrand
and David Woodhouse, with the fix suggested by Peter Zijlstra.
- Now that there is only one flavor of RCU in any running kernel,
there is also only on rcu_data structure per CPU. This means
that the rcu_dynticks structure can be merged into the rcu_data
structure, a task taken on by this branch. This branch also
contains a -rt-related fix from Mike Galbraith.

Implements counter freezing for Arch Perfmon v4 (Skylake and
newer). This allows to speed up the PMI handler by avoiding
unnecessary MSR writes and make it more accurate.
The Arch Perfmon v4 PMI handler is substantially different than
the older PMI handler.
Differences to the old handler:
- It relies on counter freezing, which eliminates several MSR
writes from the PMI handler and lowers the overhead significantly.
It makes the PMI handler more accurate, as all counters get
frozen atomically as soon as any counter overflows. So there is
much less counting of the PMI handler itself.
With the freezing we don't need to disable or enable counters or
PEBS. Only BTS which does not support auto-freezing still needs to
be explicitly managed.
- The PMU acking is done at the end, not the beginning.
This makes it possible to avoid manual enabling/disabling
of the PMU, instead we just rely on the freezing/acking.
- The APIC is acked before reenabling the PMU, which avoids
problems with LBRs occasionally not getting unfreezed on Skylake.
- Looping is only needed to workaround a corner case which several PMIs
are very close to each other. For common cases, the counters are freezed
during PMI handler. It doesn't need to do re-check.
This patch:
- Adds code to enable v4 counter freezing
- Fork <=v3 and >=v4 PMI handlers into separate functions.
- Add kernel parameter to disable counter freezing. It took some time to
debug counter freezing, so in case there are new problems we added an
option to turn it off. Would not expect this to be used until there
are new bugs.
- Only for big core. The patch for small core will be posted later
separately.
Performance:
When profiling a kernel build on Kabylake with different perf options,
measuring the length of all NMI handlers using the nmi handler
trace point:
V3 is without counter freezing.
V4 is with counter freezing.
The value is the average cost of the PMI handler.
(lower is better)

The success of a cache pseudo-locked region is measured using
performance monitoring events that are programmed directly at the time
the user requests a measurement.
Modifying the performance event registers directly is not appropriate
since it circumvents the in-kernel perf infrastructure that exists to
manage these resources and provide resource arbitration to the
performance monitoring hardware.
The cache pseudo-locking measurements are modified to use the in-kernel
perf infrastructure. Performance events are created and validated with
the appropriate perf API. The performance counters are still read as
directly as possible to avoid the additional cache hits. This is
done safely by first ensuring with the perf API that the counters have
been programmed correctly and only accessing the counters in an
interrupt disabled section where they are not able to be moved.
As part of the transition to the in-kernel perf infrastructure the L2
and L3 measurements are split into two separate measurements that can
be triggered independently. This separation prevents additional cache
misses incurred during the extra testing code used to decide if a
L2 and/or L3 measurement should be made.

New code introduced by commit bf9346f5d4 ("gpiolib: Identify arrays
matching GPIO hardware") forcibly tries to find an array member which
has its array index number equal to its hardware pin number and set
up an array info for possible fast bitmap processing of all arrray
pins belonging to that chip which also satisfy that numbering rule.
Depending on array content, it may happen that consecutive array
members which belong to the same chip but don't have array indexes
equal to their pin hardware numbers will be split into groups, some of
them processed together via the fast bitmap path, and rest of them
separetely. However, applications may expect all those pins being
processed together with a single call to .set_multiple() chip callback,
like that was done before the change.
Limit applicability of fast bitmap processing path to cases where all
pins of consecutive array members starting from 0 which belong to the
same chip have their hardware numbers equal to their corresponding
array indexes. That should still speed up processing of applications
using whole GPIO banks as I/O ports, while not breaking simultaneous
manipulation of consecutive pins of the same chip which don't follow
the equal numbering rule.

I swear I would have sent it the same to Linus! The main cause for
this is that I was on vacation until two weeks ago and it took a while
to sort all the pending patches between 4.19 and 4.20, test them and
so on.
It's mostly small bugfixes and cleanups, mostly around x86 nested
virtualization. One important change, not related to nested
virtualization, is that the ability for the guest kernel to trap CPUID
instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is now
masked by default. This is because the feature is detected through an
MSR; a very bad idea that Intel seems to like more and more. Some
applications choke if the other fields of that MSR are not initialized
as on real hardware, hence we have to disable the whole MSR by default,
as was the case before Linux 4.12.

In 2011 the commit bf859f84a1
("gpio/dt: Refine GPIO device tree binding") introduced an
experimental BNF notation for defining a regular grammar for
the GPIO phandles used by different devices.
This was an interesting approach, and shows that we have long
nutured the idea to formally verify device tree files using
regular grammar.
Most if not all other bindings use natural language to define
the bindings, and the recent thinking for verifying device
tree files is to use JSON schemas in separate definitions.
Cut the BNF business and replace it with natural language
so that it becomes more human-readable for now.

Disabling access to reads of this MSR gives userspace the control to "expose"

today, guests that read this MSR would get unpopulated information if userspace
hadn't already set it (and prior to this patch series, only the CPUID faulting

40GbE Intel Wired LAN Driver Updates 2018-09-18
This series contains changes to i40evf so that it becomes a more
generic virtual function driver for current and future silicon.
While doing the rename of i40evf to a more generic name of iavf,
we also put the driver on a severe diet due to how much of the
code was unneeded or was unused. The outcome is a lean and mean
virtual function driver that continues to work on existing 40GbE
(i40e) virtual devices and prepped for future supported devices,
like the 100GbE (ice) virtual devices.
This solves 2 issues we saw coming or were already present, the
first was constant code duplication happening with i40e/i40evf,
when much of the duplicate code in the i40evf was not used or was
not needed. The second was to remove the future confusion of why
future VF devices that were not considered "40GbE" only devices
were supported by i40evf.
The thought is that iavf will be the virtual function driver for
all future devices, so it should have a "generic" name to properly
represent that it is the VF driver for multiple generations of
devices.
The last patch in this series is unreleated to the iavf conversion
and just has to do with a MODULE_LICENSE correction.
Known Caveats:
Existing user space configurations may have to change, but the module
alias in patch 1 helps a bit here.

for now. Basically this is the simplest patch that gets
the rename done and will be followed by other patches that
rename the internal functions.
This patch also addresses a couple of string/name issues
and updates the Copyright year.
Also, made sure to add a MODULE_ALIAS to the old name.

"This contains some minor cleanups and fixes:
- a new knob for controlling scrubbing of pages returned by the Xen
balloon driver to the Xen hypervisor to address a boot performance
issue seen in large guests booted pre-ballooned
- a fix of a regression in the gntdev driver which made it impossible
to use fully virtualized guests (HVM guests) with a 4.19 based dom0
- a fix in Xen cpu hotplug functionality which could be triggered by
wrong admin commands (setting number of active vcpus to 0)
One further note: the patches have all been under test for several

merge conflicts"
* tag 'for-linus-4.19c-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
xen/gntdev: fix up blockable calls to mn_invl_range_start
xen: fix GCC warning and remove duplicate EVTCHN_ROW/EVTCHN_COL usage
xen: avoid crash in disable_hotplug_cpu
xen/balloon: add runtime control for scrubbing ballooned out pages
xen/manage: don't complain about an empty value in control/sysrq node
Scrubbing pages on initial balloon down can take some time, especially
in nested virtualization case (nested EPT is slow). When HVM/PVH guest is
started with memory= significantly lower than maxmem=, all the extra
pages will be scrubbed before returning to Xen. But since most of them
weren't used at all at that point, Xen needs to populate them first
(from populate-on-demand pool). In nested virt case (Xen inside KVM)
this slows down the guest boot by 15-30s with just 1.5GB needed to be
returned to Xen.
Add runtime parameter to enable/disable it, to allow initially disabling
scrubbing, then enable it back during boot (for example in initramfs).
Such usage relies on assumption that a) most pages ballooned out during
initial boot weren't used at all, and b) even if they were, very few
secrets are in the guest at that time (before any serious userspace
kicks in).
Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also
enabled by default), controlling default value for the new runtime
switch.

Certain GPIO array lookup results may map directly to GPIO pins of a
single GPIO chip in hardware order. If that condition is recognized
and handled efficiently, significant performance gain of get/set array
functions may be possible.
While processing a request for an array of GPIO descriptors, identify
those which represent corresponding pins of a single GPIO chip. Skip
over pins which require open source or open drain special processing.
Moreover, identify pins which require inversion. Pass a pointer to
that information with the array to the caller so it can benefit from
enhanced performance as soon as get/set array functions can accept and
make efficient use of it.

All current users are updated as well.

We currently do not notify all gmaps when using gmap_pmdp_xchg(), due
to locking constraints. This makes ucontrol VMs, which is the only VM
type that creates multiple gmaps, incompatible with huge pages. Also
we would need to hold the guest_table_lock of all gmaps that have this
vmaddr maped to synchronize access to the pmd.
ucontrol VMs are rather exotic and creating a new locking concept is
no easy task. Hence we return EINVAL when trying to active
KVM_CAP_S390_HPAGE_1M and report it as being not available when
checking for it.

the same information as the filenames are generally quite descriptive as
a short introduction to what the file covers (it should not surprise
anyone what Documentation/sched/sched-design-CFS.txt covers)
A few years back it was mentioned that these files were no longer really
needed, and they have since then grown further out of date, so perhaps
it is time to just throw them out.
A short status yields the following _outdated_ 00-INDEX files, first
counter is files listed in 00-INDEX but missing in the directory, last
is files present but not listed in 00-INDEX.
List of outdated 00-INDEX:
Documentation: (4/10)
Documentation/sysctl: (0/1)
Documentation/timers: (1/0)
Documentation/blockdev: (3/1)
Documentation/w1/slaves: (0/1)
Documentation/locking: (0/1)
Documentation/devicetree: (0/5)
Documentation/power: (1/1)
Documentation/powerpc: (0/5)
Documentation/arm: (1/0)
Documentation/x86: (0/9)
Documentation/x86/x86_64: (1/1)
Documentation/scsi: (4/4)
Documentation/filesystems: (2/9)
Documentation/filesystems/nfs: (0/2)
Documentation/cgroup-v1: (0/2)
Documentation/kbuild: (0/4)
Documentation/spi: (1/0)
Documentation/virtual/kvm: (1/0)
Documentation/scheduler: (0/2)
Documentation/fb: (0/1)
Documentation/block: (0/1)
Documentation/networking: (6/37)
Documentation/vm: (1/3)
Then there are 364 subdirectories in Documentation/ with several files that
are missing 00-INDEX alltogether (and another 120 with a single file and no
00-INDEX).
I don't really have an opinion to whether or not we /should/ have 00-INDEX,
but the above 00-INDEX should either be removed or be kept up to date. If
we should keep the files, I can try to keep them updated, but I rather not
if we just want to delete them anyway.
As a starting point, remove all index-files and references to 00-INDEX and
see where the discussion is going.

The dtb= parameter is no longer the primary mechanism for providing a
devicetree to the kernel. Now either firmware or the boot selector (ex.
Grub) should provide the devicetree and dtb= should only be used for
debug or when using firmware that doesn't understand DT.
Update the EFI stub documentation to reflect the current usage.

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.
This is helpful for configuration (e.g: none behaves dramatically
different wrt. bridges) as well as for packet capture tools when there
is not a proper Ethernet type available.

These are unused, undesired, and have never actually been used by
anybody. The original authors of this code have changed their mind about
its inclusion. While originally proposed for disk encryption on low-end
devices, the idea was discarded [1] in favor of something else before
that could really get going. Therefore, this patch removes Speck.
