Alexandre Belloni cd6720ba02 dt-bindings: microchip: atmel,at91rm9200-tcb: Add atmel,tcb-pwm
Move the TCB pwm nodes under their parent. This removes the need for the
tc-block property as there is now a child-parent relationship between the
TC channel and the TC block.

Move the documentation to the main file.

Linus Torvalds 48c1c40ab4 ARM: SoC drivers for v5.11
There are a couple of subsystems maintained by other people that
 merge their drivers through the SoC tree, those changes include:
 
  - The SCMI firmware framework gains support for sensor notifications
    and for controlling voltage domains.
 
  - A large update for the Tegra memory controller driver, integrating
    it better with the interconnect framework
 
  - The memory controller subsystem gains support for Mediatek MT8192
 
  - The reset controller framework gains support for sharing pulsed
    resets
 
 For Soc specific drivers in drivers/soc, the main changes are
 
  - The Allwinner/sunxi MBUS gets a rework for the way it handles
    dma_map_ops and offsets between physical and dma address spaces.
 
  - An errata fix plus some cleanups for Freescale Layerscape SoCs
 
  - A cleanup for renesas drivers regarding MMIO accesses.
 
  - New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
 
  - New SoC specific drivers for Aspeed AST2600 LPC bus control
    and SoC identification.
 
  - Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
    and SDX55.
 
  - A rework of the TI AM33xx 'genpd' power domain support to use
    information from DT instead of platform data
 
  - Support for TI AM64x SoCs
 
  - Allow building some Amlogic drivers as modules instead of built-in
 
 Finally, there are numerous cleanups and smaller bug fixes for
 Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
 Renesas, and Xilinx SoCs.
 
 There is a trivial conflict in the cedrus driver, with two branches
 adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
 remove/remove conflict in linux/dma-mapping.h.

Linus Torvalds 9805529ec5 ARM: device tree updates for 5.11
Across all platforms, there is a continued move towards DT schema for
 validating the dts files. As a result there are bug fixes for mistakes
 that are found using these schema, in addition to warnings from the
 dtc compiler.
 
 As usual, many changes are for adding support for additional on-chip
 and on-board components in the machines we already support.
 
 The newly supported SoCs for this release are:
 
  - MStar Infinity2M, a low-end IP camera chip based on a dual-core
    Cortex-A7, otherwise similar to the Infinity chip we already support.
    This is also known as the SigmaStar SSD202D, and we add support for
    the Honestar ssd201htv2 development kit.
 
  - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
    (BMC), in the same family as the NPCM750. This gets used in the Ampere
    Altra based "Fii Kudo" server and the Quanta GSJ, both of which are
    added as well.
 
  - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
    Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
    GT-AC5300 high-end WiFi router based on this chip.
 
  - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
    meant for faster Chromebooks and tablets. It gets added along with
    its reference design.
 
  - Mediatek MT6779 (Helio P90) is a high-end phone chip from last year's
    generation, also added along with its reference board.  This one is
    still based on Cortex-A75/A55.
 
  - Mediatek MT8167 is a version of the already supported MT8516 chip,
    both based on Cortex-A35. It gets added along with the "Pumpkin"
    single board computer, but is likely to also make its way into low-end
    tablets in the future.
 
 For the already supported chips, there are a number of new boards.
 Interestingly there are more 32-bit machines added this time than
 64-bit. Here is a brief list of the new boards:
 
  - Three new Mikrotik router variants based on Marvell Prestera
    98DX3236, a close relative of the more common Armada XP
 
  - A reference board for the Marvell Armada 382
 
  - Three new servers using ASpeed baseboard management controllers,
    the actual machines being from Bytedance, Facebook and IBM,
    and one machine using the Nuvoton NPCM750 BMC.
 
  - The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412.
 
  - The usual set of 32-bit i.MX industrial/embedded hardware:
    * Protonic WD3 (tractor e-cockpit)
    * Kamstrup OMNIA Flex Concentrator (smart grid platform)
    * Van der Laan LANMCU (food storage)
    * Altesco I6P (vehicle inspection stations)
    * PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard
 
  - DH electronics STM32MP157C DHCOM, a PicoITX carrier board
    for the aleady supported DHCOM module
 
  - Three new Allwinner SoC based single-board computers:
    * NanoPi R1 (H3 based)
    * FriendlyArm ZeroPi (H3 based)
    * Elimo Initium SBC (S3 based)
 
  - Ouya Game Console based on Nvidia Tegra 3
 
  - Version 5 of the already supported Zynq Z-Turn MYIR Board
 
  - LX2162AQDS, a reference platform for NXP Layerscape
    LX2162A, which is a repackaged 16-core LX2160A
 
  - A series of Kontron i.MX8M Mini baseboard/SoM versions
 
  - Espressobin Ultra, a new variant of the popular Armada 3700 based board,
 
  - IEI Puzzle-M801, a rackmount network appliance based on
    Marvell Armada 8040
 
  - Microsoft Lumia 950 XL, a phone
 
  - HDK855 and HDK865 Hardware development kits for Qualcomm
    sm8250 and sm8150, respectively
 
  - Three new board variants of the "Trogdor" Chromebook
    (sc7180)
 
  - New board variants of the Renesas based "Kingfisher" and
    "HiHope" reference boards
 
  - Kobol Helios64, an open source NAS appliance based on Rockchips
    RK3399
 
  - Engicam PX30.Core, a SoM based on Rockchip PX30, along with
    a few carrier boards.
 
 There is one conflict in mt6577_auxadc.txt, which got replaced in
 another tree and modified here, the modification is already part of
 the new file.

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.11 kernel.

  Drivers, drivers and drivers. Not a single core change.

  Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot
  SoCs.

  As part of the modularization attempt, I applied one patch affecting
  the firmware subsystem as a functional (not syntactic/semantic)
  dependency and then it blew up in our face, so I had to revert it,
  bummer. It will come in later, through that subsystem, I guess.

  New drivers:

   - New driver for the Microchip Serial GPIO "SGPIO".

   - Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver.

  New subdrivers:

   - Intel Lakefield subdriver.

   - Intel Elkhart Lake subdriver.

   - Intel Alder Lake-S subdriver.

   - Qualcomm MSM8953 subdriver.

   - Qualcomm SDX55 subdriver.

Pull IOMMU updates from Will Deacon:
 "There's a good mixture of improvements to the core code and driver
  changes across the board.

  One thing worth pointing out is that this includes a quirk to work
  around behaviour in the i915 driver (see 65f746e828 ("iommu: Add
  quirk for Intel graphic devices in map_sg")), which otherwise
  interacts badly with the conversion of the intel IOMMU driver over to
  the DMA-IOMMU APU but has being fixed properly in the DRM tree.

  We'll revert the quirk later this cycle once we've confirmed that
  things don't fall apart without it.

  Summary:

   - IOVA allocation optimisations and removal of unused code

   - Introduction of DOMAIN_ATTR_IO_PGTABLE_CFG for parameterising the
     page-table of an IOMMU domain

   - Support for changing the default domain type in sysfs

   - Optimisation to the way in which identity-mapped regions are
     created

   - Driver updates:
       * Arm SMMU updates, including continued work on Shared Virtual
         Memory
       * Tegra SMMU updates, including support for PCI devices
       * Intel VT-D updates, including conversion to the IOMMU-DMA API

Linus Torvalds 7a932e5702 asm-generic: cross-architecture timer cleanup
This cleans up two ancient timer features that were never completed in
 the past, CONFIG_GENERIC_CLOCKEVENTS and CONFIG_ARCH_USES_GETTIMEOFFSET.
 
 There was only one user left for the ARCH_USES_GETTIMEOFFSET variant
 of clocksource implementations, the ARM EBSA110 platform. Rather than
 changing to use modern timekeeping, we remove the platform entirely as
 Russell no longer uses his machine and nobody else seems to have one
 any more.
 
 The conditional code for using arch_gettimeoffset() is removed as
 a result.
 
 For CONFIG_GENERIC_CLOCKEVENTS, there are still a couple of platforms
 not using clockevent drivers: parisc, ia64, most of m68k, and one
 Arm platform. These all do timer ticks slighly differently, and this
 gets cleaned up to the point they at least all call the same helper
 function. Instead of most platforms using 'select GENERIC_CLOCKEVENTS'
 in Kconfig, the polarity is now reversed, with the few remaining ones
 selecting LEGACY_TIMER_TICK instead.

Matteo Croce 2c622ed0ea reboot: allow to specify reboot mode via sysfs
The kernel cmdline reboot= option offers some sort of control on how the
reboot is issued.

We don't always know in advance what type of reboot to perform.

Sometimes a warm reboot is preferred to persist certain memory regions
across the reboot.  Others a cold one is needed to apply a future system
update that makes a memory memory model change, like changing the base
page size or resizing a persistent memory region.

Or simply we want to enable reboot_force because we noticed that
something bad happened.

Add handles in sysfs to allow setting these reboot options, so they can
be changed when the system is booted, other than at boot time.

The handlers are under <sysfs>/kernel/reboot, can be read to get the
current configuration and written to alter it.

	# cd /sys/kernel/reboot/

	# grep . *
	cpu:0
	force:0
	mode:cold
	type:acpi

	# echo 2 >cpu
	# echo yes >force
	# echo soft >mode
	# echo bios >type

	# grep . *
	cpu:2
	force:1
	mode:soft
	type:bios

Before setting anything, check for CAP_SYS_BOOT capability, so it's
possible to allow an unpriviledged process to change these settings simply
by relaxing the handles permissions, without opening them to the world.

Anand K Mistry fe71988834 proc: provide details on indirect branch speculation
Similar to speculation store bypass, show information about the indirect
branch speculation mode of a task in /proc/$pid/status.

For testing/benchmarking, I needed to see whether IB (Indirect Branch)
speculation (see Spectre-v2) is enabled on a task, to see whether an
IBPB instruction should be executed on an address space switch.
Unfortunately, this information isn't available anywhere else and
currently the only way to get it is to hack the kernel to expose it
(like this change).  It also helped expose a bug with conditional IB
speculation on certain CPUs.

Another place this could be useful is to audit the system when using
sanboxing.  With this change, I can confirm that seccomp-enabled
process have IB speculation force disabled as expected when the kernel
command line parameter `spectre_v2_user=seccomp`.

Since there's already a 'Speculation_Store_Bypass' field, I used that
as precedent for adding this one.

Pull execve updates from Eric Biederman:
 "This set of changes ultimately fixes the interaction of posix file
  lock and exec. Fundamentally most of the change is just moving where
  unshare_files is called during exec, and tweaking the users of
  files_struct so that the count of files_struct is not unnecessarily
  played with.

  Along the way fcheck and related helpers were renamed to more
  accurately reflect what they do.

  There were also many other small changes that fell out, as this is the
  first time in a long time much of this code has been touched.

  Benchmarks haven't turned up any practical issues but Al Viro has
  observed a possibility for a lot of pounding on task_lock. So I have
  some changes in progress to convert put_files_struct to always rcu
  free files_struct. That wasn't ready for the merge window so that will
  have to wait until next time"

Merge tag 'nfsd-5.11' of git://git.linux-nfs.org/projects/cel/cel-2.6

Pull nfsd updates from Chuck Lever:
 "Several substantial changes this time around:

   - Previously, exporting an NFS mount via NFSD was considered to be an
     unsupported feature. With v5.11, the community has attempted to
     make re-exporting a first-class feature of NFSD.

     This would enable the Linux in-kernel NFS server to be used as an
     intermediate cache for a remotely-located primary NFS server, for
     example, even with other NFS server implementations, like a NetApp
     filer, as the primary.

   - A short series of patches brings support for multiple RPC/RDMA data
     chunks per RPC transaction to the Linux NFS server's RPC/RDMA
     transport implementation.

     This is a part of the RPC/RDMA spec that the other premiere
     NFS/RDMA implementation (Solaris) has had for a very long time, and
     completes the implementation of RPC/RDMA version 1 in the Linux
     kernel's NFS server.

   - Long ago, NFSv4 support was introduced to NFSD using a series of C
     macros that hid dprintk's and goto's. Over time, the kernel's XDR
     implementation has been greatly improved, but these C macros have
     remained and become fallow. A series of patches in this pull
     request completely replaces those macros with the use of current
     kernel XDR infrastructure. Benefits include:

       - More robust input sanitization in NFSD's NFSv4 XDR decoders.

       - Make it easier to use common kernel library functions that use
         XDR stream APIs (for example, GSS-API).

       - Align the structure of the source code with the RFCs so it is
         easier to learn, verify, and maintain our XDR implementation.

       - Removal of more than a hundred hidden dprintk() call sites.

       - Removal of some explicit manipulation of pages to help make the
         eventual transition to xdr->bvec smoother.

   - On top of several related fixes in 5.10-rc, there are a few more
     fixes to get the Linux NFSD implementation of NFSv4.2 inter-server
     copy up to speed.

  And as usual, there is a pinch of seasoning in the form of a
  collection of unrelated minor bug fixes and clean-ups.

  Many thanks to all who contributed this time around!"

Linus Torvalds ef9df00117 remoteproc updates for v5.11
This introduces support for controlling the TI PRU, adds hooks for
 remoteproc drivers to override the default ELF based coredump format,
 introduces a library function for coredumps using named sections (aka
 the Qualcomm "minidump" format). It fixes a problem with inconsistent
 notifications sent by the Qualcomm sysmon driver to the remote
 processors and it migrates the Qualcomm MSS driver to use power-domains
 for resources that aren't actually regulators.  Lastly it contains a
 number of fixes for minor bugs and build warnings throughout the
 drivers.

   touchpad on convertibles when they are transitioned into tablet mode

 - now that ordinary input devices can be configured for polling mode,
   dedicated input polling device implementation has been removed

Linus Torvalds 605ea5aafe spi: Updates for v5.11
The big change this release has been some excellent work from Lukas
 Wunner which closes a bunch of holes in the cleanup paths for drivers,
 mainly introduced as a result of devm conversions causing bad
 interactions with the support SPI has for allocating the bus and driver
 data together.  Together with some of the other work done it feels like
 we've turned the corner on several long standing pain points with the
 API.
 
  - Many cleanups around probe/remove and error handling from Lukas
    Wunner and Uwe Kleine-König, and further fixes around PM from Zhang
    Qilong.
  - Provide a mask for which bits of the mode can safely be configured by
    drivers and use that to fix an issue with the ADS7846 driver.
  - Documentation of the expected interactions between SPI and GPIO level
    chip select polarity configuration from H. Nikolaus Schaller,
    hopefully we're pretty much at the end of sorting out the
    interactions there.  Thanks to Nikolaus, Sven Van Asbroeck and Linus
    Walleij for this.
  - DMA support for Allwinner sun6i controllers.
  - Support for Canaan K210 Designware implementations and Intel Adler Lake.

Linus Torvalds 2dda5700ef regulator: Updates for v5.11
This has been a quiet release for the regulator API, a few new drivers
 and the usual fixes and cleanup traffic but not much else going on:
 
  - Optimisations for the handling of voltage enumeration, especially
    with sparse selector sets, from Claudiu Beznea.
  - Support for several ARM SCMI regulators, Dialog DA9121, NXP PF8x00,
    Qualcomm PMX55, PM8350 and PM8350c
 
 The addition of the SCMI regulator driver (which controls regulators via
 system firmware) means that we've pulled in the support for the underlying
 firmware operations from the firmware tree.

Hugh Dickins 15b4473617 mm/lru: revise the comments of lru_lock
Since we changed the pgdat->lru_lock to lruvec->lru_lock, it's time to fix
the incorrect comments in code.  Also fixed some zone->lru_lock comment
error from ancient time.  etc.

I struggled to understand the comment above move_pages_to_lru() (surely
it never calls page_referenced()), and eventually realized that most of
it had got separated from shrink_active_list(): move that comment back.

Linus Torvalds c367caf1a3 sound updates for 5.11-rc1
Lots of changes (slightly more code increase than usual) at this
 time, while most of code changes are ASoC driver-specific.
 Here goes some highlight:
 
 Core:
 * The new auxiliary bus implementation for Intel DSP, which will
   be used by other drivers as well
 * Lots of ASoC core cleanups and refactoring
 * UBSAN and KCSAN fixes in rawmidi, sequencer and a few others
 * Compress-offload API enhancement for the pause during draining
 
 HD- and USB-audio:
 * Enhancements of the USB-audio implicit feedback support,
   including better full-duplex operations
 * Continued CA0132 improvements and fixes
 * A few new quirk entries, HDMI audio fixes
 
 ASoC:
 * Support for boot time selection of Intel DSP firmware, which
   should help distros/users testing new stuff more easily;
   the kconfig was moved to boot time option, too
 * Some basic DPCM support in audio graph card
 * Removal of old pre-DT Freescale drivers
 * Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
   Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek
   RT715, Qualcomm SM8250 and simple GPIO based muxes

Minchan Kim 194e28da1a zram: add stat to gather incompressible pages since zram set up
Currently, zram supports the stat via /sys/block/zram/mm_stat to represent
how many of incompressible pages are stored at the moment but it couldn't
show how many times incompressible pages were wrote down since zram set
up.  It's also good indication to see how zram is effective in the system.

Minchan Kim 0d8359620d zram: support page writeback
There is demand to writeback specific process pages to backing store
instead of all idles pages in the system due to storage wear out concerns
and to launching latency of apps which are most of the time idle but are
critical for resume latency.

This patch extends the writeback knob to support a specific page
writeback.

Lokesh Gidra d0d4730ac2 userfaultfd: add user-mode only option to unprivileged_userfaultfd sysctl knob
With this change, when the knob is set to 0, it allows unprivileged users
to call userfaultfd, like when it is set to 1, but with the restriction
that page faults from only user-mode can be handled.  In this mode, an
unprivileged user (without SYS_CAP_PTRACE capability) must pass
UFFD_USER_MODE_ONLY to userfaultd or the API will fail with EPERM.

This enables administrators to reduce the likelihood that an attacker with
access to userfaultfd can delay faulting kernel code to widen timing
windows for other exploits.

The default value of this knob is changed to 0.  This is required for
correct functioning of pipe mutex.  However, this will fail postcopy live
migration, which will be unnoticeable to the VM guests.  To avoid this,
set 'vm.userfault = 1' in /sys/sysctl.conf.

The main reason this change is desirable as in the short term is that the
Android userland will behave as with the sysctl set to zero.  So without
this commit, any Linux binary using userfaultfd to manage its memory would
behave differently if run within the Android userland.  For more details,
refer to Andrea's reply [1].

Mike Rapoport 5e545df329 arm: remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
ARM is the only architecture that defines CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
which in turn enables memmap_valid_within() function that is intended to
verify existence  of struct page associated with a pfn when there are holes
in the memory map.

However, the ARCH_HAS_HOLES_MEMORYMODEL also enables HAVE_ARCH_PFN_VALID
and arch-specific pfn_valid() implementation that also deals with the holes
in the memory map.

The only two users of memmap_valid_within() call this function after
a call to pfn_valid() so the memmap_valid_within() check becomes redundant.

Remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL and memmap_valid_within() and rely
entirely on ARM's implementation of pfn_valid() that is now enabled
unconditionally.

Shakeel Butt f0c0c115fb mm: memcontrol: account pagetables per node
For many workloads, pagetable consumption is significant and it makes
sense to expose it in the memory.stat for the memory cgroups.  However at
the moment, the pagetables are accounted per-zone.  Converting them to
per-node and using the right interface will correctly account for the
memory cgroups as well.

Johannes Weiner b8eddff888 mm: memcontrol: add file_thp, shmem_thp to memory.stat
As huge page usage in the page cache and for shmem files proliferates in
our production environment, the performance monitoring team has asked for
per-cgroup stats on those pages.

We already track and export anon_thp per cgroup.  We already track file
THP and shmem THP per node, so making them per-cgroup is only a matter of
switching from node to lruvec counters.  All callsites are in places where
the pages are charged and locked, so page->memcg is stable.

John Hubbard a9bed1e1c2 selftests/vm: only some gup_test items are really benchmarks
Therefore, some minor cleanup and improvements are in order:

1. Rename the other items appropriately.

2. Stop reporting timing information on the non-benchmark items. It's
   still being recorded and is available, but there's no point in
   cluttering up the report with data that no one reasonably needs to
   check.

3. Don't do iterations, for non-benchmark items.

4. Print out a shorter, more appropriate report for the non-benchmark
   tests.

5. Add the command that was run, to the report. This really helps, as
   there are quite a lot of options now.

6. Use a larger integer type for cmd, now that it's being compared
   Otherwise it doesn't work, because in this case cmd is about 3 billion,
   which is the perfect size for problems with signed vs unsigned int.

John Hubbard 9c84f22926 mm/gup_benchmark: rename to mm/gup_test
Patch series "selftests/vm: gup_test, hmm-tests, assorted improvements", v3.

Summary: This series provides two main things, and a number of smaller
supporting goodies.  The two main points are:

1) Add a new sub-test to gup_test, which in turn is a renamed version
   of gup_benchmark.  This sub-test allows nicer testing of dump_pages(),
   at least on user-space pages.

   For quite a while, I was doing a quick hack to gup_test.c whenever I
   wanted to try out changes to dump_page().  Then Matthew Wilcox asked me
   what I meant when I said "I used my dump_page() unit test", and I
   realized that it might be nice to check in a polished up version of
   that.

   Details about how it works and how to use it are in the commit
   description for patch #6 ("selftests/vm: gup_test: introduce the
   dump_pages() sub-test").

2) Fixes a limitation of hmm-tests: these tests are incredibly useful,
   but only if people actually build and run them.  And it turns out that
   libhugetlbfs is a little too effective at throwing a wrench in the
   works, there.  So I've added a little configuration check that removes
   just two of the 21 hmm-tests, if libhugetlbfs is not available.

   Further details in the commit description of patch #8
   ("selftests/vm: hmm-tests: remove the libhugetlbfs dependency").

Other smaller things that this series does:

a) Remove code duplication by creating gup_test.h.

b) Clear up the sub-test organization, and their invocation within
   run_vmtests.sh.

c) Other minor assorted improvements.

The one exception is for the actual gup benchmark test itself.

The current code already does a *little* bit more than benchmarking, and
definitely covers more than get_user_pages_fast().  More importantly,
however, subsequent patches are about to add some functionality that is
non-benchmark related.

Closely related changes:

* Kconfig: in addition to renaming the options from GUP_BENCHMARK to
  GUP_TEST, update the help text to reflect that it's no longer a
  benchmark-only test.

Liam Mark 9cc7e96aa8 mm/page_owner: record timestamp and pid
Collect the time for each allocation recorded in page owner so that
allocation "surges" can be measured.

Record the pid for each allocation recorded in page owner so that the
source of allocation "surges" can be better identified.

The above is very useful when doing memory analysis.  On a crash for
example, we can get this information from kdump (or ramdump) and parse it
to figure out memory allocation problems.

Please note that on x86_64 this increases the size of struct page_owner
from 16 bytes to 32.

Vlastimil: it's not a functionality intended for production, so unless
somebody says they need to enable page_owner for debugging and this
increase prevents them from fitting into available memory, let's not
complicate things with making this optional.

Bartosz Golaszewski f0dbd2bd1c mm: slab: provide krealloc_array()
When allocating an array of elements, users should check for
multiplication overflow or preferably use one of the provided helpers
like: kmalloc_array().

There's no krealloc_array() counterpart but there are many users who use
regular krealloc() to reallocate arrays.  Let's provide an actual
krealloc_array() implementation.

While at it: add some documentation regarding krealloc.

Linus Torvalds edd7ab7684 The new preemtible kmap_local() implementation:
- Consolidate all kmap_atomic() internals into a generic implementation
     which builds the base for the kmap_local() API and make the
     kmap_atomic() interface wrappers which handle the disabling/enabling of
     preemption and pagefaults.
 
   - Switch the storage from per-CPU to per task and provide scheduler
     support for clearing mapping when scheduling out and restoring them
     when scheduling back in.
 
   - Merge the migrate_disable/enable() code, which is also part of the
     scheduler pull request. This was required to make the kmap_local()
     interface available which does not disable preemption when a mapping
     is established. It has to disable migration instead to guarantee that
     the virtual address of the mapped slot is the same accross preemption.
 
   - Provide better debug facilities: guard pages and enforced utilization
     of the mapping mechanics on 64bit systems when the architecture allows
     it.
 
   - Provide the new kmap_local() API which can now be used to cleanup the
     kmap_atomic() usage sites all over the place. Most of the usage sites
     do not require the implicit disabling of preemption and pagefaults so
     the penalty on 64bit and 32bit non-highmem systems is removed and quite
     some of the code can be simplified. A wholesale conversion is not
     possible because some usage depends on the implicit side effects and
     some need to be cleaned up because they work around these side effects.
 
     The migrate disable side effect is only effective on highmem systems
     and when enforced debugging is enabled. On 64bit and 32bit non-highmem
     systems the overhead is completely avoided.

     make the kmap_atomic() interface wrappers which handle the
     disabling/enabling of preemption and pagefaults.

   - Switch the storage from per-CPU to per task and provide scheduler
     support for clearing mapping when scheduling out and restoring them
     when scheduling back in.

   - Merge the migrate_disable/enable() code, which is also part of the
     scheduler pull request. This was required to make the kmap_local()
     interface available which does not disable preemption when a
     mapping is established. It has to disable migration instead to
     guarantee that the virtual address of the mapped slot is the same
     across preemption.

   - Provide better debug facilities: guard pages and enforced
     utilization of the mapping mechanics on 64bit systems when the
     architecture allows it.

   - Provide the new kmap_local() API which can now be used to cleanup
     the kmap_atomic() usage sites all over the place. Most of the usage
     sites do not require the implicit disabling of preemption and
     pagefaults so the penalty on 64bit and 32bit non-highmem systems is
     removed and quite some of the code can be simplified. A wholesale
     conversion is not possible because some usage depends on the
     implicit side effects and some need to be cleaned up because they
     work around these side effects.

     The migrate disable side effect is only effective on highmem
     systems and when enforced debugging is enabled. On 64bit and 32bit
     non-highmem systems the overhead is completely avoided"

  - The consolidation work to reclaim TIF flags on x86 and also for non-x86
    specific TIF flags which are solely relevant for syscall related work
    and have been moved into their own storage space. The x86 specific part
    had to be merged in to avoid a major conflict.
 
  - The TIF_NOTIFY_SIGNAL work which replaces the inefficient signal
    delivery mode of task work and results in an impressive performance
    improvement for io_uring. The non-x86 consolidation of this is going to
    come seperate via Jens.
 
  - The selective syscall redirection facility which provides a clean and
    efficient way to support the non-Linux syscalls of WINE by catching them
    at syscall entry and redirecting them to the user space emulation. This
    can be utilized for other purposes as well and has been designed
    carefully to avoid overhead for the regular fastpath. This includes the
    core changes and the x86 support code.
 
  - Simplification of the context tracking entry/exit handling for the users
    of the generic entry code which guarantee the proper ordering and
    protection.
 
  - Preparatory changes to make the generic entry code accomodate S390
    specific requirements which are mostly related to their syscall restart
    mechanism.

Linus Torvalds ff6135959a A much quieter cycle for documentation (happily), with, one hopes, the bulk
of the churn behind us.  Significant stuff in this pull includes:
 
  - A set of new Chinese translations
  - Italian translation updates
  - A mechanism from Mauro to automatically format Documentation/features
    for the built docs
  - Automatic cross references without explicit :ref: markup
  - A new reset-controller document
  - An extensive new document on reporting problems from Thorsten
 
 That last patch also adds the CC-BY-4.0 license to LICENSES/dual; there was
 some discussion on this, but we seem to have consensus and an ack from Greg
 for that addition.

Linus Torvalds 0ca2ce81eb arm64 updates for 5.11:
- Expose tag address bits in siginfo. The original arm64 ABI did not
   expose any of the bits 63:56 of a tagged address in siginfo. In the
   presence of user ASAN or MTE, this information may be useful. The
   implementation is generic to other architectures supporting tags (like
   SPARC ADI, subject to wiring up the arch code). The user will have to
   opt in via sigaction(SA_EXPOSE_TAGBITS) so that the extra bits, if
   available, become visible in si_addr.
 
 - Default to 32-bit wide ZONE_DMA. Previously, ZONE_DMA was set to the
   lowest 1GB to cope with the Raspberry Pi 4 limitations, to the
   detriment of other platforms. With these changes, the kernel scans the
   Device Tree dma-ranges and the ACPI IORT information before deciding
   on a smaller ZONE_DMA.
 
 - Strengthen READ_ONCE() to acquire when CONFIG_LTO=y. When building
   with LTO, there is an increased risk of the compiler converting an
   address dependency headed by a READ_ONCE() invocation into a control
   dependency and consequently allowing for harmful reordering by the
   CPU.
 
 - Add CPPC FFH support using arm64 AMU counters.
 
 - set_fs() removal on arm64. This renders the User Access Override (UAO)
   ARMv8 feature unnecessary.
 
 - Perf updates: PMU driver for the ARM DMC-620 memory controller, sysfs
   identifier file for SMMUv3, stop event counters support for i.MX8MP,
   enable the perf events-based hard lockup detector.
 
 - Reorganise the kernel VA space slightly so that 52-bit VA
   configurations can use more virtual address space.
 
 - Improve the robustness of the arm64 memory offline event notifier.
 
 - Pad the Image header to 64K following the EFI header definition
   updated recently to increase the section alignment to 64K.
 
 - Support CONFIG_CMDLINE_EXTEND on arm64.
 
 - Do not use tagged PC in the kernel (TCR_EL1.TBID1==1), freeing up 8
   bits for PtrAuth.
 
 - Switch to vmapped shadow call stacks.
 
 - Miscellaneous clean-ups.

Zhen Lei 4aa5b78fb5 dt-bindings: i2c: dw: cancel mandatory requirements for "#address-cells" and "#size-cells"
The "#address-cells" and "#size-cells" are required only when the I2C
controller has subnodes. However, some I2C controllers defined in
"arch/arm64/boot/dts/amd/" and "arch/arm64/boot/dts/hisilicon/"
directories do not have child nodes. So they don't need these two
properties and don't write them explicitly.

Therefore, setting properties "#address-cells" and "#size-cells" as
"required" in this yaml file causes the following warnings:
/root/linux-next/arch/arm64/boot/dts/hisilicon/hi6220-hikey.dt.yaml: \
i2c@f7100000: '#address-cells' is a required property

Takashi Iwai 598100be30 ASoC: Updates for v5.11
There's a lot of changes here but mostly cleanups and driver specific
 things, the most user visible change is the support for boot time
 selection of Intel DSP firmware which will make it easier for people to
 move over to the preferred modern implementations in distros and other
 large scale deployments.
 
 This also includes a merge of the new auxillary bus which was done in
 anticipation of use by the Intel DSP drivers which didn't quite make it.
 
  - Lots more cleanups and simplifications from Morimoto-san.
  - Support for some basic DPCM systems in the audio graph card from
    Sameer Pujar.
  - Remove some old pre-DT Freescale drivers for platforms that are now
    DT only.
  - Move selection of which Intel DSP implementation to use to boot time
    rather than requiring it to be selected at build time.
  - Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
    Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek RT715,
    Qualcomm SM8250 and simple GPIO based muxes.

Optionally allow using "user.overlay." namespace instead of
"trusted.overlay."

This is necessary for overlayfs to be able to be mounted in an unprivileged
namepsace.

Make the option explicit, since it makes the filesystem format be
incompatible.

Disable redirect_dir and metacopy options, because these would allow
privilege escalation through direct manipulation of the
"user.overlay.redirect" or "user.overlay.metacopy" xattrs.

According to the X.25 documentation, there was a plan to implement

X.25 code. At this time it is unlikely that it would ever finish so it
may be better to remove those code stubs.

Also change the documentation to make it clear that this is not a ongoing

Maciej S. Szmigiero 34c0f6f269 KVM: mmu: Fix SPTE encoding of MMIO generation upper half
Commit cae7ed3c2c ("KVM: x86: Refactor the MMIO SPTE generation handling")
cleaned up the computation of MMIO generation SPTE masks, however it
introduced a bug how the upper part was encoded:
SPTE bits 52-61 were supposed to contain bits 10-19 of the current
generation number, however a missing shift encoded bits 1-10 there instead
(mostly duplicating the lower part of the encoded generation number that
then consisted of bits 1-9).

In the meantime, the upper part was shrunk by one bit and moved by
subsequent commits to become an upper half of the encoded generation number
(bits 9-17 of bits 0-17 encoded in a SPTE).

In addition to the above, commit 56871d444b ("KVM: x86: fix overlap between SPTE_MMIO_MASK and generation")
has changed the SPTE bit range assigned to encode the generation number and
the total number of bits encoded but did not update them in the comment
attached to their defines, nor in the KVM MMU doc.
Let's do it here, too, since it is too trivial thing to warrant a separate
commit.

Rafael J. Wysocki d3569c149d Update devfreq for 5.11
Detailed description for this pull request:
 
 1. Update devfreq core
 - Add new devfreq_frequency tracepoint to show the frequency change
 information.
 
 - Add governor feature flag. The devfreq governor is able to
 have the specific flag in order to contain the non-common feature.
 For example, if governor contains the 'immutable' feature, don't allow
 user to change the governor via sysfs.
 
 - Add governor sysfs attribute flag for each sysfs file. Prior to that
 devfreq subsystem show the all sysfs files regardless of governor type.
 But, some sysfs fils are not supported on the specific devfreq governor.
 In order to show the only supported sysfs files according to the governor,
 clarify the access permission of sysfs attributes according to governor.
 When adding the devfreq governor, can specify the available attribute
 information by using DEVFREQ_GOV_ATTR_* constant variable. The user can
 read or write the sysfs attributes in accordance to the specified attributes.
 
 - Clean-up the code to remove the duplicate code for the devfreq tracepoint
 and to remove redundant governor_name field from struct devfreq
 
 2. Update exynos-bus.c devfreq driver
 - Add interconnect API support for the Samsung Exynos Bus Frequency driver
 of exynos-bus.c. Complementing the devfreq driver with an interconnect
 functionality allows to ensure the QoS requirements of devices accessing
 the system memory (e.g. video processing devices) are fulfilled
 and allows to avoid issues like the DMA underrun.
 
 3. Update tegra devfreq driver
 - Add interconnect support and OPP interface for tegra30-devfreq.c.
 Also, it is to guarantee the QoS requirement of some devices like
 display controller.
 
 - Move tegra20-devfreq.c from drivers/devfreq/ into driver/memory/tegra/
 in order to use the more proper monitoring feature such as EMC_STAT
 which is based in driver/memory/tegra/.
 
 - Separate the configuration information for different SoC on
 tegra30-devfrqe.c. The tegra30-devfreq.c had been supported both
 tegra30-actmon and tegra124-actmon devices. In order to use
 the more correct configuration data, separate them.
 
 - Use dev_err_probe() to handle the deferred probe error on tegra30-devfreq.c.
 
 4. Pull the request of 'Tegra SoC and clock controller changes for v5.11'
 sent by Krzysztof Kozlowski <krzk@kernel.org> in order to prevent the
 build error.

This standardizes its documentation, allows validating with Makefile
checks and helps writing DTS files.

Noticeable changes:
1. Dropped "Partitions can be represented by sub-nodes of a flash
   device." as we also support subpartitions (don't have to be part of
   flash device node)
2. Dropped "to Linux" as bindings are meant to be os agnostic.

thus fail to validate.

Fix this by documenting the interrupts property.
