      Pull devicetree updates from Rob Herring:
       "DT core:
      
         - Add support for generating DT nodes for PCI devices. This is the
           groundwork for applying overlays to PCI devices containing
           non-discoverable downstream devices.
      
         - DT unittest additions to check reverted changesets, to test for
           refcount issues, and to test unresolved symbols. Also, various
           clean-ups of the unittest along the way.
      
         - Refactor node and property manipulation functions to better share
           code with old API and changeset API
      
         - Refactor changeset print functions to a common implementation
      
         - Move some platform_device specific functions into of_platform.c
      
        Bindings:
      
         - Treewide fixing of typos
      
         - Treewide clean-up of SPDX tags to use 'OR' consistently
      
         - Last chunk of dropping unnecessary quotes. With that, the check for
           unnecessary quotes is enabled in yamllint.
      
         - Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
           bindings to DT schema format
      
         - Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450
           Inline Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt
           controller, Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings
      
         - Fixes for Rockchip DWC PCI binding
      
         - Ensure all properties are evaluated on USB connector schema
      
         - Fix dt-check-compatible script to find of_device_id instances with
           compiler annotations"

         - TI AM62P5, a variant of the existing Sitara AM62x family
      
         - Intel Agilex5, an FPGFA platform that includes an Cortex-A76/A55

         - Qualcomm SM4450 (Snapdragon 4 Gen 2) is a new low-end mobile phone
           platform.
      
        In total, 29 machines get added, which is low because of the summer
        break. These cover SoCs from Aspeed, Broadcom, NXP, Samsung, ST,
        Allwinner, Amlogic, Intel, Qualcomm, Rockchip, TI and T-Head. Most of
        these are development and reference boards.
      
        Despite not adding a lot of new machines, there are over 700 patches
        in total, most of which are cleanups and minor fixes"

      Pull ARM SoC driver updates from Arnd Bergmann:
       "The main change this time was the introduction of the drivers/genpd
        subsystem that gets split out from drivers/soc to keep common
        functionality together.
      
        The SCMI driver subsystem gets an update to version 3.2 of the
        specification. There are also updates to memory, reset and other
        firmware drivers.
      
        On the soc driver side, the updates are mostly cleanups across a
        number of Arm platforms. On driver for loongarch adds power management
        for DT based systems, another driver is for HiSilicon's Arm server
        chips with their HCCS system health interface.
      
        The remaining updates for the most part add support for additional
        hardware in existing drivers or contain minor cleanups. Most of these
        are for the Qualcomm Snapdragon platform"

       "We've received a fairly wide range of changes at this time, including
        for ALSA and ASoC core, but all of them are rather small changes.
      
        Here are some highlights:
      
        ALSA / ASoC Core:
         - Fixes of inconsistent locking around control API helpers
         - A few new control API functions and cleanups
         - Workarounds for potential UAFs by delayed kobj releases
         - Unified PCM copy ops with iov_iter
         - Continued efforts for ASoC API cleanups
      
        ASoC:
         - An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in
           some IIO changes
         - Create a library function for intlog10() and use it in the NAU8825
           driver
         - Convert drivers to use the more modern maple tree register cache
         - Lots of work on the SOF framework, AMD and Intel drivers, including
           a lot of cleanup and new device support
         - Standardization of the presentation of jacks from drivers
         - Provision of some generic sound card DT properties
         - Support for AMD Van Gogh, AMD machines with MAX98388 and NAU8821,
           AWInic AW88261, Cirrus Logic CS35L36 and CS42L43, various Intel

           MT7986, NXP i.MX93, RealTek RT1017 and StarFive JH7110
      
        Others:
         - New test coverage including ASoC and topology tests in KUnit; this
           also involves enabling UML builds of ALSA since that's the default
           KUnit test environment which pulls in the addition of some stubs to
           the driver
         - More enhancement of pcmtest driver
         - A few fixes / enhancements of MIDI 2.0 UMP core
         - Using PCI definitions in allover HD-audio code
         - Support for Cirrus CS35L56 and TI TAS2781 HD-audio sub-codecs

         the branch one last time since I'm still technically maintainer. :P
      
       - Create a maintainer entry profile for XFS in which we lay out the
         various roles that I have played for many years.  Aside from release
         manager, the remaining roles are as yet unfilled.
      
       - Start merging online repair -- we now have in-memory pageable memory
         for staging btrees, a bunch of pending fixes, and we've started the
         process of refactoring the scrub support code to support more of
         repair.  In particular, reaping of old blocks from damaged structures.

      Pull x86 apic updates from Dave Hansen:
       "This includes a very thorough rework of the 'struct apic' handlers.
        Quite a variety of them popped up over the years, especially in the
        32-bit days when odd apics were much more in vogue.
      
        The end result speaks for itself, which is a removal of a ton of code
        and static calls to replace indirect calls.
      
        If there's any breakage here, it's likely to be around the 32-bit
        museum pieces that get light to no testing these days.
      
        Summary:
      
         - Rework apic callbacks, getting rid of unnecessary ones and
           coalescing lots of silly duplicates.
      
         - Use static_calls() instead of indirect calls for apic->foo()

       - Prevent kprobes on compiler generated CFI checking code.
      
         The compiler generates an instruction sequence for indirect call
         checks. If this sequence is modified with a kprobe, then the check

      x86: bring back rep movsq for user access on CPUs without ERMS · ca96b162
      Mateusz Guzik authored
      Intel CPUs ship with ERMS for over a decade, but this is not true for
      AMD.  In particular one reasonably recent uarch (EPYC 7R13) does not
      have it (or at least the bit is inactive when running on the Amazon EC2
      cloud -- I found rather conflicting information about AMD CPUs vs the
      extension).
      
      Hand-rolled mov loops executing in this case are quite pessimal compared
      to rep movsq for bigger sizes.  While the upper limit depends on uarch,
      everyone is well south of 1KB AFAICS and sizes bigger than that are
      common.
      
      While technically ancient CPUs may be suffering from rep usage, gcc has
      been emitting it for years all over kernel code, so I don't think this
      is a legitimate concern.
      
      Sample result from read1_processes from will-it-scale (4KB reads/s):
      
        before:   1507021
        after:    1721828 (+14%)
      
      Note that the cutoff point for rep usage is set to 64 bytes, which is
      way too conservative but I'm sticking to what was done in 47ee3f1d
      ("x86: re-introduce support for ERMS copies for user space accesses").
      That is to say *some* copies will now go slower, which is fixable but
      beyond the scope of this patch.

       - Add proper multi-LSM support for xattrs in the
         security_inode_init_security() hook
      
         Historically the LSM layer has only allowed a single LSM to add an
         xattr to an inode, with IMA/EVM measuring that and adding its own as
         well. As we work towards promoting IMA/EVM to a "proper LSM" instead
         of the special case that it is now, we need to better support the
         case of multiple LSMs each adding xattrs to an inode and after
         several attempts we now appear to have something that is working
         well. It is worth noting that in the process of making this change we
         uncovered a problem with Smack's SMACK64TRANSMUTE xattr which is also
         fixed in this pull request.
      
       - Additional LSM hook constification
      
         Two patches to constify parameters to security_capget() and
         security_binder_transfer_file(). While I generally don't make a
         special note of who submitted these patches, these were the work of
         an Outreachy intern, Khadija Kamran, and that makes me happy;
         hopefully it does the same for all of you reading this.
      
       - LSM hook comment header fixes
      
         One patch to add a missing hook comment header, one to fix a minor
         typo.
      
       - Remove an old, unused credential function declaration
      
         It wasn't clear to me who should pick this up, but it was trivial,
         obviously correct, and arguably the LSM layer has a vested interest
         in credentials so I merged it. Sadly I'm now noticing that despite my
         subject line cleanup I didn't cleanup the "unsued" misspelling, sigh

      Pull selinux updates from Paul Moore:
       "Thirty three SELinux patches, which is a pretty big number for us, but
        there isn't really anything scary in here; in fact we actually manage
        to remove 10 lines of code with this :)
      
         - Promote the SELinux DEBUG_HASHES macro to CONFIG_SECURITY_SELINUX_DEBUG
      
           The DEBUG_HASHES macro was a buried SELinux specific preprocessor
           debug macro that was a problem waiting to happen. Promoting the
           debug macro to a proper Kconfig setting should help both improve
           the visibility of the feature as well enable improved test
           coverage. We've moved some additional debug functions under the
           CONFIG_SECURITY_SELINUX_DEBUG flag and we may see more work in the
           future.
      
         - Emit a pr_notice() message if virtual memory is executable by default
      
           As this impacts the SELinux access control policy enforcement, if
           the system's configuration is such that virtual memory is
           executable by default we print a single line notice to the console.
      
         - Drop avtab_search() in favor of avtab_search_node()
      
           Both functions are nearly identical so we removed avtab_search()
           and converted the callers to avtab_search_node().
      
         - Add some SELinux network auditing helpers
      
           The helpers not only reduce a small amount of code duplication, but
           they provide an opportunity to improve UDP flood performance
           slightly by delaying initialization of the audit data in some
           cases.
      
         - Convert GFP_ATOMIC allocators to GFP_KERNEL when reading SELinux policy
      
           There were two SELinux policy load helper functions that were
           allocating memory using GFP_ATOMIC, they have been converted to
           GFP_KERNEL.
      
         - Quiet a KMSAN warning in selinux_inet_conn_request()
      
           A one-line error path (re)set patch that resolves a KMSAN warning.
           It is important to note that this doesn't represent a real bug in
           the current code, but it quiets KMSAN and arguably hardens the code
           against future changes.
      
         - Cleanup the policy capability accessor functions
      
           This is a follow-up to the patch which reverted SELinux to using a
           global selinux_state pointer. This patch cleans up some artifacts
           of that change and turns each accessor into a one-line READ_ONCE()
           call into the policy capabilities array.
      
         - A number of patches from Christian Göttsche
      
           Christian submitted almost two-thirds of the patches in this pull
           request as he worked to harden the SELinux code against type
           differences, variable overflows, etc.
      
         - Support for separating early userspace from the kernel in policy,
           with a later revert
      
           We did have a patch that added a new userspace initial SID which
           would allow SELinux to distinguish between early user processes
           created before the initial policy load and the kernel itself.
      
           Unfortunately additional post-merge testing revealed a problematic
           interaction with an old SELinux userspace on an old version of
           Ubuntu so we've reverted the patch until we can resolve the
           compatibility issue.
      
         - Remove some outdated comments dealing with LSM hook registration
      
           When we removed the runtime disable functionality we forgot to
           remove some old comments discussing the importance of LSM hook
           registration ordering.
      
         - Minor administrative changes
      
           Stephen Smalley updated his email address and "debranded" SELinux
           from "NSA SELinux" to simply "SELinux". We've come a long way from
           the original NSA submission and I would consider SELinux a true
           community project at this point so removing the NSA branding just
           makes sense"

       "Six audit patches, the highlights are:
      
         - Add an explicit cond_resched() call when generating PATH records
      
           Certain tracefs/debugfs operations can generate a *lot* of audit
           PATH entries and if one has an aggressive system configuration (not
           the default) this can cause a soft lockup in the audit code as it
           works to process all of these new entries.
      
           This is in sharp contrast to the common case where only one or two
           PATH entries are logged. In order to fix this corner case without
           excessively impacting the common case we're adding a single
           cond_rescued() call between two of the most intensive loops in the
           __audit_inode_child() function.
      
         - Various minor cleanups

       "Fairly quiet round in terms of features, mostly just improvements all
        over the map for existing code. In detail:
      
         - Initial support for socket operations through io_uring. Latter half
           of this will likely land with the 6.7 kernel, then allowing things
           like get/setsockopt (Breno)
      
         - Cleanup of the cancel code, and then adding support for canceling
           requests with the opcode as the key (me)
      
         - Improvements for the io-wq locking (me)
      
         - Fix affinity setting for SQPOLL based io-wq (me)
      
         - Remove the io_uring userspace code. These were added initially as
           copies from liburing, but all of them have since bitrotted and are
           way out of date at this point. Rather than attempt to keep them in
           sync, just get rid of them. People will have liburing available
           anyway for these examples. (Pavel)
      
         - Series improving the CQ/SQ ring caching (Pavel)
      
         - Misc fixes and cleanups (Pavel, Yue, me)"

      Pull sysctl updates from Luis Chamberlain:
       "Long ago we set out to remove the kitchen sink on kernel/sysctl.c
        arrays and placings sysctls to their own sybsystem or file to help
        avoid merge conflicts. Matthew Wilcox pointed out though that if we're
        going to do that we might as well also *save* space while at it and
        try to remove the extra last sysctl entry added at the end of each
        array, a sentintel, instead of bloating the kernel by adding a new
        sentinel with each array moved.
      
        Doing that was not so trivial, and has required slowing down the moves
        of kernel/sysctl.c arrays and measuring the impact on size by each new
        move.
      
        The complex part of the effort to help reduce the size of each sysctl
        is being done by the patient work of el señor Don Joel Granados. A lot
        of this is truly painful code refactoring and testing and then trying
        to measure the savings of each move and removing the sentinels.
        Although Joel already has code which does most of this work,
        experience with sysctl moves in the past shows is we need to be
        careful due to the slew of odd build failures that are possible due to
        the amount of random Kconfig options sysctls use.
      
        To that end Joel's work is split by first addressing the major
        housekeeping needed to remove the sentinels, which is part of this
        merge request. The rest of the work to actually remove the sentinels
        will be done later in future kernel releases.
      
        The preliminary math is showing this will all help reduce the overall
        build time size of the kernel and run time memory consumed by the
        kernel by about ~64 bytes per array where we are able to remove each
        sentinel in the future. That also means there is no more bloating the
        kernel with the extra ~64 bytes per array moved as no new sentinels
        are created"

      Pull modules updates from Luis Chamberlain:
       "Summary of the changes worth highlighting from most interesting to
        boring below:
      
         - Christoph Hellwig's symbol_get() fix to Nvidia's efforts to
           circumvent the protection he put in place in year 2020 to prevent
           proprietary modules from using GPL only symbols, and also ensuring
           proprietary modules which export symbols grandfather their taint.
      
           That was done through year 2020 commit 262e6ae7 ("modules:
           inherit TAINT_PROPRIETARY_MODULE"). Christoph's new fix is done by
           clarifing __symbol_get() was only ever intended to prevent module
           reference loops by Linux kernel modules and so making it only find
           symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic
           used by Nvidia was to use symbol_get() to purposely swift through
           proprietary module symbols and completely bypass our traditional
           EXPORT_SYMBOL*() annotations and community agreed upon
           restrictions.
      
           A small set of preamble patches fix up a few symbols which just
           needed adjusting for this on two modules, the rtc ds1685 and the
           networking enetc module. Two other modules just needed some build
           fixing and removal of use of __symbol_get() as they can't ever be
           modular, as was done by Arnd on the ARM pxa module and Christoph
           did on the mmc au1xmmc driver.
      
           This is a good reminder to us that symbol_get() is just a hack to
           address things which should be fixed through Kconfig at build time
           as was done in the later patches, and so ultimately it should just
           go.
      
         - Extremely late minor fix for old module layout 055f23b7
           ("module: check for exit sections in layout_sections() instead of
           module_init_section()") by James Morse for arm64. Note that this
           layout thing is old, it is *not* Song Liu's commit ac3b4328
           ("module: replace module_layout with module_memory"). The issue
           however is very odd to run into and so there was no hurry to get
           this in fast.
      
         - Although the fix did not go through the modules tree I'd like to
           highlight the fix by Peter Zijlstra in commit 54097309
           ("x86/static_call: Fix __static_call_fixup()") now merged in your
           tree which came out of what was originally suspected to be a
           fallout of the the newer module layout changes by Song Liu commit
           ac3b4328 ("module: replace module_layout with module_memory")
           instead of module_init_section()"). Thanks to the report by
           Christian Bricart and the debugging by Song Liu & Peter that turned
           to be noted as a kernel regression in place since v5.19 through
           commit ee88d363 ("x86,static_call: Use alternative RET
           encoding").
      
           I highlight this to reflect and clarify that we haven't seen more
           fallout from ac3b4328 ("module: replace module_layout with
           module_memory").
      
         - RISC-V toolchain got mapping symbol support which prefix symbols
           with "$" to help with alignment considerations for disassembly.
      
           This is used to differentiate between incompatible instruction
           encodings when disassembling. RISC-V just matches what ARM/AARCH64
           did for alignment considerations and Palmer Dabbelt extended
           is_mapping_symbol() to accept these symbols for RISC-V. We already
           had support for this for all architectures but it also checked for
           the second character, the RISC-V check Dabbelt added was just for
           the "$". After a bit of testing and fallout on linux-next and based
           on feedback from Masahiro Yamada it was decided to simplify the
           check and treat the first char "$" as unique for all architectures,
           and so we no make is_mapping_symbol() for all archs if the symbol
           starts with "$".
      
           The most relevant commit for this for RISC-V on binutils was:
      
             https://sourceware.org/pipermail/binutils/2021-July/117350.html
      
         - A late fix by Andrea Righi (today) to make module zstd
           decompression use vmalloc() instead of kmalloc() to account for
           large compressed modules. I suspect we'll see similar things for
           other decompression algorithms soon.

           Chen Jiahao"

         - Randomized kmalloc caches, by GONG, Ruiqi.
      
           A new opt-in hardening feature to make heap spraying harder. It
           creates multiple (16) copies of kmalloc caches, reducing the chance
           of an attacker-controllable allocation site to land in the same
           slab as e.g. an allocation site with use-after-free vulnerability.
      
           The selection of the copy is derived from the allocation site
           address, including a per-boot random seed.
      
         - Stronger typing for hardened freelists in SLUB, by Jann Horn
      
           Introduces a custom type for hardened freelist entries instead of
           "void *" as those are not directly dereferencable. While reviewing
           this, I've noticed opportunities for further cleanups in that code
           and added those on top"

      bus: fsl-mc: Use common ranges functions · 09959520
      Rob Herring authored
      Since commit 3d5089c4 ("of/address: Add support for 3 address cell
      bus"), the DT address functions can handle translating buses with 3
      address cells. Replace the custom code with the for_each_of_range()
      iterator.
      
      The original code had fallbacks to get "#address-cells"/"#size-cells"
      from the bus parent node if they are missing. This is non-standard
      behavior, and AFAICT the upstream .dts files never relied on that.
