       "These update the ACPICA code in the kernel to the most recent upstream
        revision including (but not limited to) new material introduced in the
        6.4 version of the spec, update message printing in the ACPI-related
        code, address a few issues and clean up code in a number of places.
      
        Specifics:

         - Rearrange message printing in ACPI-related code to avoid using the
           ACPICA's internal message printing macros outside ACPICA and do
           some related code cleanups (Rafael Wysocki).
      
         - Modify the device enumeration code to turn off all of the unused
           ACPI power resources at the end (Rafael Wysocki).
      
         - Change the ACPI power resources handling code to turn off unused
           ACPI power resources without checking their status which should not
           be necessary by the spec (Rafael Wysocki).
      
         - Add empty stubs for CPPC-related functions to be used when
           CONFIG_ACPI_CPPC_LIB is not set (Rafael Wysocki).
      
         - Simplify device enumeration code (Rafael Wysocki).
      
         - Change device enumeration code to use match_string() for string
           matching (Andy Shevchenko).
      
         - Modify irqresource_disabled() to retain the resouce flags that have
           been set already (Angela Czubak).
      
         - Add native backlight whitelist entry for GA401/GA502/GA503 (Luke
           Jones).
      
         - Modify the ACPI backlight driver to let the native backlight
           handling take over on hardware-reduced systems (Hans de Goede).
      
         - Introduce acpi_dev_get() and switch over the ACPI core code to
           using it (Andy Shevchenko).
      
         - Use kobj_attribute as callback argument instead of a local struct
           type in the CPPC linrary code (Nathan Chancellor).
      
         - Drop unneeded initializatio of a static variable from the ACPI
           processor driver (Tian Tao).
      
         - Drop unnecessary local variable assignment from the ACPI APEI code
           (Colin Ian King).
      
         - Document for_each_acpi_dev_match() macro (Andy Shevchenko).
      
         - Address assorted coding style issues in multiple places (Xiaofei

      Pull hwmon updates from Guenter Roeck:
       "The most notable change is the removal of the amd_energy driver. It
        was rendered all but unusable by making its attributes privileged-only
        to work around a security issue. A suggested remedy was rejected by
        AMD, so the only real solution was to remove the driver. For the
        future, we'll have to make sure that no privileged-access-only drivers
        are accepted into the hwmon subsystem in the first place. The hwmon
        ABI document was updated accordingly.
      
        Other changes:
      
        PMBus drivers:
         - Added driver for MAX15301
         - Added driver for BluTek BPA-RS600
         - Added driver for fsp-3y PSUs and PDUs
         - Added driver for Infineon IR36021
         - Added driver for ST STPDDC60
         - Added support for TI TPS53676 to tps53679 driver
         - Introduced PMBUS symbol namespace. This was made necessary by a
           suggestion to use its exported functions from outside the hwmon
           subsystem.
         - Minor improvements and bug fixes
      
        New drivers:
         - Driver for NZXT Kraken X42/X52/X62/X72
      
        Driver enhancements:
         - Added support for Intel D5005 to intel-m10-bmc-hwmon driver
         - Added support for NCT6686D to nct6683 driver
      
        Other:
         - Converted sch5627 and amd9240 drivers to
           hwmon_device_register_with_info()
         - Added support for fan drawers capability and present registers to
           mlxreg-fan driver
         - Added Dell Latitude E7440 to fan control whitelist in dell-smm
           driver
         - Replaced snprintf in show functions with sysfs_emit. Done with
           coccinelle script for all drivers to preempt endless per-driver
           submissions of the same change.
         - Use kobj_to_dev().  Another coccinelle based change to preempt
           endless per-driver submissions of the same change.
         - Various minor fixes and improvements"

      Pull btrfs updates from David Sterba:
       "The updates this time are mostly stabilization, preparation and minor
        improvements.
      
        User visible improvements:
      
         - readahead for send, improving run time of full send by 10% and for
           incremental by 25%
      
         - make reflinks respect O_SYNC, O_DSYNC and S_SYNC flags
      
         - export supported sectorsize values in sysfs (currently only page
           size, more once full subpage support lands)
      
         - more graceful errors and warnings on 32bit systems when logical
           addresses for metadata reach the limit posed by unsigned long in
           page::index
            - error: fail mount if there's a metadata block beyond the limit
            - error: new metadata block would be at unreachable address
            - warn when 5/8th of the limit is reached, for 4K page systems
              it's 10T, for 64K page it's 160T
      
         - zoned mode
            - relocated zones get reset at the end instead of discard
            - automatic background reclaim of zones that have 75%+ of unusable
              space, the threshold is tunable in sysfs
      
        Fixes:
      
         - fsync and tree mod log fixes
      
         - fix inefficient preemptive reclaim calculations
      
         - fix exhaustion of the system chunk array due to concurrent
           allocations
      
         - fix fallback to no compression when racing with remount
      
         - preemptive fix for dm-crypt on zoned device that does not properly
           advertise zoned support
      
        Core changes:
      
         - add inode lock to synchronize mmap and other block updates (eg.
           deduplication, fallocate, fsync)
      
         - kmap conversions to new kmap_local API
      
         - subpage support (continued)
            - new helpers for page state/extent buffer tracking
            - metadata changes now support read and write
      
         - error handling through out relocation call paths
      
         - many other cleanups and code simplifications"

       "In this cycle, we would like to introduce a new feature called big
        pcluster so EROFS can compress file data into more than 1 fs block and
        different pcluster size can be selected for each (sub-)files by
        design.
      
        The current EROFS test results on my laptop are [1]:

        which has been verified but I'd like warn it as experimental for a
        while. This matches erofs-utils dev branch and I'll also release a new
        userspace version for this later.
      
        Apart from that, several improvements are also included: eg complete a
        missing case for inplace I/O, optimize endio decompression logic for
        non-atomic contexts and support adjustable sliding window size, ... In
        addition to those, there are some cleanups as always.
      
        Summary:
      
         - avoid memory failure when applying rolling decompression
      
         - optimize endio decompression logic for non-atomic contexts
      
         - complete a missing case which can be safely selected for inplace

      Pull file locking updates from Jeff Layton:
       "When we reworked the blocked locks into a tree structure instead of a
        flat list a few releases ago, we lost the ability to see all of the
        file locks in /proc/locks. Luo's patch fixes it to dump out all of the
        blocked locks instead, which restores the full output.
      
        This changes the format of /proc/locks as the blocked locks are shown
        at multiple levels of indentation now, but lslocks (the only common
        program I've ID'ed that scrapes this info) seems to be OK with that.
      
        Tian also contributed a small patch to remove a useless assignment"

      Pull ARM devicetree updates from Arnd Bergmann:
       "There are six new SoCs added this time.
      
        Apple M1 and Nuvoton WPCM450 have separate branches because they are
        new SoC families that require changes outside of device tree files.
        The other four are variations of already supported chips and get
        merged through this branch:
      
         - STMicroelectronics STM32H750 is one of many variants of STM32
           microcontrollers based on the Cortex-M7 core.
      
           This is particularly notable since we rarely add support for new
           MMU-less chips these days. In this case, the board that gets added
           along with the platform is not a SoC reference platform but the
           "Art Pi" (https://art-pi.gitee.io/website/) machine that was
           originally design for the RT-Thread RTOS.
      
         - NXP i.MX8QuadMax is a variant of the growing i.MX8
           embedded/industrial SoC family, using two Cortex-A72 and four
           Cortex-A53 cores.
      
           It gets added along with its reference board, the "NXP i.MX8QuadMax
           Multisensory Enablement Kit".
      
         - Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon
           7c) that is used in some Chromebooks and Windows laptops.
      
           Only a reference board is added for the moment.
      
         - TI AM64x Sita4ra is a new version of the K3 SoC family for
           industrial control, motor control, remote IO, IoT gateway etc.,
           similar to the older AM65x family.
      
           Two reference machines are added alongside.
      
        Among the newly added machines, there is a very clear skew towards
        64-bit machines now, with 12 32-bit machines compared to 23 64-bit
        machines. The full list sorted by SoC is:
      
         - ASpeed AST2500 BMC: ASRock E3C246D4I Xeon server board
         - Allwinner A10: Topwise A721 Tablet
         - Amlogic GXL: MeCool KII TV box
         - Amlogic GXM: Mecool KIII, Minix Neo U9-H TV boxes
         - Broadcom BCM4908: TP-Link Archer C2300 V1 router
         - MStar SSD202D: M5Stack UnitV2 camera
         - Marvell Armada 38x: ATL-x530 ethernet switch
         - Mediatek MT8183 Chromebooks: Lenovo 10e, Acer Spin 311, Asus Flip
           CM3, Asus Detachable CM3
         - Mediatek MT8516/MT8183: OLogic Pumpkin Board
         - NXP i.MX7: reMarkable Tablet
         - NXP i.MX8M: Kontron pitx-imx8m, Engicam i.Core MX8M Mini
         - Nuvoton NPCM730: Quanta GBS BMC
         - Qualcomm X55: Telit FN980 TLB SoM, Thundercomm TurboX T55 SoM
         - Qualcomm MSM8998: OnePlus 5/5T phones
         - Qualcomm SM8350: Snapdragon 888 Mobile Hardware Development Kit
         - Rockchip RK3399: NanoPi R4S board
         - STM32MP1: Engicam MicroGEA STM32MP1 MicroDev 2.0 and SOM, EDIMM2.2
           Starter Kit, Carrier, SOM
         - TI AM65: Siemens SIMATIC IOT2050 gateway
      
        There is notable work going into extending already supported machines
        and SoCs:
      
         - ASpeed AST2500
         - Allwinner A23, A83t, A31, A64, H6
         - Amlogic G12B
         - Broadcom BCM4908
         - Marvell Armada 7K/8K/CN91xx
         - Mediatek MT6589, MT7622, MT8173, MT8183, MT8195
         - NXP i.MX8Q, i.MX8MM, i.MX8MP
         - Qualcomm MSM8916, SC7180, SDM845, SDX55, SM8350
         - Renesas R-Car M3, V3U
         - Rockchip RK3328, RK3399
         - STEricsson U8500
         - STMicroelectronics STM32MP141
         - Samsung Exynos 4412
         - TI K3-AM65, K3-J7200
         - TI OMAP3
      
        Among the treewide cleanups and bug fixes, two parts stand out:
      
         - There are a number of cleanups for issues pointed out by 'make
           dtbs_check' this time, and I expect more to come in the future as
           we increasingly check for regressions.
      
         - After a change to the MMC subsystem that can lead to unpredictable
           device numbers, several platforms add 'aliases' properties for
           these to give each MMC controller a fixed number"

         - ti-sysc needs iorange check improved when the interconnect target
           module has no control registers listed
         - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to
           avoid issues with missing resources and unnecessary deferred probe
         - ti-sysc debug option can now detect more devices
         - ti-sysc now warns if an old incomplete devicetree data is found as
           we now rely on it being complete for am3 and 4
         - soc init code needs to check for prcm and prm nodes for omap4/5 and
           dra7
         - omap-prm driver needs to enable autoidle retention support for
           omap4

        Lots of little churn in here, and some larger churn as well. Major
        things are:
      
         - removal of wimax drivers, no one has this hardware anymore for this
           failed "experiment".
      
         - removal of the Google gasket driver, turns out no one wanted to
           maintain it or cares about it anymore, so they asked for it to be
           removed.
      
         - comedi finally moves out of the staging directory into drivers/comedi
      
           This is one of the oldest kernel subsystems around, being created
           in the 2.0 kernel days, and was one of the first things added to
           drivers/staging/ when that was created over 15 years ago.
      
           It should have been moved out of staging a long time ago, it's well
           maintained and used by loads of different devices in the real world
           every day. Nice to see this finally happen.
      
         - so many tiny coding style cleanups it's not funny.
      
           Perfect storm of at least 2 different intern project application
           deadlines combined to provide a huge number of new contributions in
           this area from people learning how to do kernel development. Great
           job to everyone involved here.

      certs: add 'x509_revocation_list' to gitignore · 81f20231
      Linus Torvalds authored
      Commit d1f04410 ("certs: Add ability to preload revocation certs")
      created a new generated file for revocation certs, but didn't tell git
      to ignore it.  Thus causing unnecessary "git status" noise after a
      kernel build with CONFIG_SYSTEM_REVOCATION_LIST enabled.
      
      Add the proper gitignore magic.

       "Support for enhanced split lock detection:
      
        Newer CPUs provide a second mechanism to detect operations with lock

        take bus lock which causes a system wide performance degradation when
        these operations happen frequently.
      
        The new mechanism is not using the #AC exception. It triggers #DB and
        is restricted to operations in user space. Kernel side split lock
        access can only be detected by the #AC based variant.
      
        Contrary to the #AC based mechanism the #DB based variant triggers
        _after_ the instruction was executed. The mechanism is CPUID
        enumerated and contrary to the #AC version which is based on the magic
        TEST_CTRL_MSR and model/family based enumeration on the way to become

      Pull entry code update from Thomas Gleixner:
       "Provide support for randomized stack offsets per syscall to make
        stack-based attacks harder which rely on the deterministic stack
        layout.
      
        The feature is based on the original idea of PaX's RANDSTACK feature,
        but uses a significantly different implementation.
      
        The offset does not affect the pt_regs location on the task stack as
        this was agreed on to be of dubious value. The offset is applied
        before the actual syscall is invoked.
      
        The offset is stored per cpu and the randomization happens at the end
        of the syscall which is less predictable than on syscall entry.
      
        The mechanism to apply the offset is via alloca(), i.e. abusing the
        dispised VLAs. This comes with the drawback that
        stack-clash-protection has to be disabled for the affected compilation
        units and there is also a negative interaction with stack-protector.
      
        Those downsides are traded with the advantage that this approach does
        not require any intrusive changes to the low level assembly entry
        code, does not affect the unwinder and the correct stack alignment is
        handled automatically by the compiler.
      
        The feature is guarded with a static branch which avoids the overhead
        when disabled.
      
        Currently this is supported for X86 and ARM64"

      Pull irq updates from Thomas Gleixner:
       "The usual updates from the irq departement:
      
        Core changes:
      
         - Provide IRQF_NO_AUTOEN as a flag for request*_irq() so drivers can
           be cleaned up which either use a seperate mechanism to prevent
           auto-enable at request time or have a racy mechanism which disables
           the interrupt right after request.
      
         - Get rid of the last usage of irq_create_identity_mapping() and
           remove the interface.
      
         - An overhaul of tasklet_disable().
      
           Most usage sites of tasklet_disable() are in task context and
           usually in cleanup, teardown code pathes. tasklet_disable()
           spinwaits for a tasklet which is currently executed. That's not
           only a problem for PREEMPT_RT where this can lead to a live lock
           when the disabling task preempts the softirq thread. It's also
           problematic in context of virtualization when the vCPU which runs
           the tasklet is scheduled out and the disabling code has to spin
           wait until it's scheduled back in.
      
           There are a few code pathes which invoke tasklet_disable() from
           non-sleepable context. For these a new disable variant which still
           spinwaits is provided which allows to switch tasklet_disable() to a
           sleep wait mechanism. For the atomic use cases this does not solve
           the live lock issue on PREEMPT_RT. That is mitigated by blocking on
           the RT specific softirq lock.
      
         - The PREEMPT_RT specific implementation of softirq processing and
           local_bh_disable/enable().
      
           On RT enabled kernels soft interrupt processing happens always in
           task context and all interrupt handlers, which are not explicitly
           marked to be invoked in hard interrupt context are forced into task
           context as well. This allows to protect against softirq processing
           with a per CPU lock, which in turn allows to make BH disabled
           regions preemptible.
      
           Most of the softirq handling code is still shared. The RT/non-RT
           specific differences are addressed with a set of inline functions
           which provide the context specific functionality. The
           local_bh_disable() / local_bh_enable() mechanism are obviously
           seperate.
      
         - The usual set of small improvements and cleanups
