      Pull btrfs updates from David Sterba:
       "There are no exciting changes for users, it's been mostly API
        conversions and some fixes or refactoring.
      
        The mount API conversion is a base for future improvements that would
        come with VFS. Metadata processing has been converted to folios, not
        yet enabling the large folios but it's one patch away once everything
        gets tested enough.
      
        Core changes:
      
         - convert extent buffers to folios:
            - direct API conversion where possible
            - performance can drop by a few percent on metadata heavy
              workloads, the folio sizes are not constant and the calculations
              add up in the item helpers
            - both regular and subpage modes
            - data cannot be converted yet, we need to port that to iomap and
              there are some other generic changes required
      
         - convert mount to the new API, should not be user visible:
            - options deprecated long time ago have been removed: inode_cache,
              recovery
            - the new logic that splits mount to two phases slightly changes
              timing of device scanning for multi-device filesystems
            - LSM options will now work (like for selinux)
      
         - convert delayed nodes radix tree to xarray, preserving the
           preload-like logic that still allows to allocate with GFP_NOFS
      
         - more validation of sysfs value of scrub_speed_max
      
         - refactor chunk map structure, reduce size and improve performance
      
         - extent map refactoring, smaller data structures, improved
           performance
      
         - reduce size of struct extent_io_tree, embedded in several
           structures
      
         - temporary pages used for compression are cached and attached to a
           shrinker, this may slightly improve performance
      
         - in zoned mode, remove redirty extent buffer tracking, zeros are
           written in case an out-of-order is detected and proper data are
           written to the actual write pointer
      
         - cleanups, refactoring, error message improvements, updated tests
      
         - verify and update branch name or tag
      
         - remove unwanted text"

      Pull xfs updates from Chandan Babu:
       "New features/functionality:
         - Online repair:
             - Reserve disk space for online repairs
             - Fix misinteraction between the AIL and btree bulkloader because
               of which the bulk load fails to queue a buffer for writeback if
               it happens to be on the AIL list
             - Prevent transaction reservation overflows when reaping blocks
               during online repair
             - Whenever possible, bulkloader now copies multiple records into
               a block
             - Support repairing of
                 1. Per-AG free space, inode and refcount btrees
                 2. Ondisk inodes
                 3. File data and attribute fork mappings
             - Verify the contents of
                 1. Inode and data fork of realtime bitmap file
                 2. Quota files
         - Introduce MF_MEM_PRE_REMOVE. This will be used to notify tasks
           about a pmem device being removed
      
        Bug fixes:
         - Fix memory leak of recovered attri intent items
         - Fix UAF during log intent recovery
         - Fix realtime geometry integer overflows
         - Prevent scrub from live locking in xchk_iget
         - Prevent fs shutdown when removing files during low free disk space

           filesystem
         - Fix an off-by-one error in xreap_agextent_binval
         - Serialize access to perag radix tree during deletion operation
         - Fix perag memory leak during growfs
         - Allow allocation of minlen realtime extent when the maximum sized
           realtime free extent is minlen in size
      
        Cleanups:
         - Remove duplicate boilerplate code spread across functionality
           associated with different log items
         - Cleanup resblks interfaces
         - Pass defer ops pointer to defer helpers instead of an enum
         - Initialize di_crc in xfs_log_dinode to prevent KMSAN warnings
         - Use static_assert() instead of BUILD_BUG_ON_MSG() to validate size
           of structures and structure member offsets. This is done in order
           to be able to share the code with userspace
         - Move XFS documentation under a new directory specific to XFS
         - Do not invoke deferred ops' ->create_done callback if the deferred
           operation does not have an intent item associated with it
         - Remove duplicate inclusion of header files from scrub/health.c
         - Refactor Realtime code
         - Cleanup attr code"

      Pull KUnit updates from Shuah Khan:
      
       - a new feature that adds APIs for managing devices introducing a set
         of helper functions which allow devices (internally a struct
         kunit_device) to be created and managed by KUnit.
      
         These devices will be automatically unregistered on test exit. These
         helpers can either use a user-provided struct device_driver, or have
         one automatically created and managed by KUnit. In both cases, the
         device lives on a new kunit_bus.
      
       - changes to switch drm/tests to use kunit devices

      Pull power management updates from Rafael Wysocki:
       "These add support for new processors (Sierra Forest, Grand Ridge and
        Meteor Lake) to the intel_idle driver, make intel_pstate run on
        Emerald Rapids without HWP support and adjust it to utilize EPP values
        supplied by the platform firmware, fix issues, clean up code and
        improve documentation.
      
        The most significant fix addresses deadlocks in the core system-wide
        resume code that occur if async_schedule_dev() attempts to run its
        argument function synchronously (for example, due to a memory
        allocation failure). It rearranges the code in question which may
        increase the system resume time in some cases, but this basically is a
        removal of a premature optimization. That optimization will be added
        back later, but properly this time.
      
        Specifics:

      Pull thermal control updates from Rafael Wysocki:
       "These add support for the D1/T113s THS controller to the sun8i driver
        and a DT-based mechanism for platforms to indicate a preference to
        reboot (instead of shutting down) on crossing a critical trip point,
        fix issues, make other improvements (in the IPA governor, the Intel
        HFI driver, the exynos driver and the thermal netlink interface among
        other places) and clean up code.
      
        One long-standing issue addressed here is that trip point crossing
        notifications sent to user space might be unreliable due to the
        incorrect handling of trip point hysteresis in the thermal core:
        multiple notifications might be sent for the same event or there might
        be events without any notification at all.
      
        Specifics:

         - Modify the thermal zone unregistration to wait for the given zone
           to go away completely before returning to the caller and rework the
           sysfs interface for trip points on top of that (Rafael J. Wysocki)
      
         - Fix a possible NULL pointer dereference in thermal zone
           registration error path (Rafael J. Wysocki)
      
         - Clean up the IPA thermal governor and modify it (with the help of a
           new governor callback) to avoid allocating and freeing memory every
           time its throttling callback is invoked (Lukasz Luba)

           changes via sysfs correctly (Lukasz Luba)

      Pull ACPI updates from Rafael Wysocki:
       "From the new features standpoint, the most significant change here is
        the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
        device enumeration code that will allow MIPI cameras to be enumerated
        through the platform firmware on systems using ACPI.
      
        Also significant is the switch-over to threaded interrupt handlers for
        the ACPI SCI and the dedicated EC interrupt (on systems where the
        former is not used) which essentially allows all ACPI code to run with
        local interrupts enabled. That should improve responsiveness
        significantly on systems where multiple GPEs are enabled and the
        handling of one SCI involves many I/O address space accesses which
        previously had to be carried out in one go with disabled interrupts on
        the local CPU.
      
        Apart from the above, the ACPI thermal zone driver will use the
        Thermal fast Sampling Period (_TFP) object if available, which should
        allow temperature changes to be followed more accurately on some
        systems, the ACPI Notify () handlers can run on all CPUs (not just on
        CPU0), which should generally speed up the processing of events
        signaled through the ACPI SCI, and the ACPI power button driver will
        trigger wakeup key events via the input subsystem (on systems where it
        is a system wakeup device)
      
        In addition to that, there are the usual bunch of fixes and cleanups.
      
        Specifics:
      
         - Add CSI-2 and DisCo for Imaging support to the ACPI device
           enumeration code (Sakari Ailus, Rafael J. Wysocki)
      
         - Adjust the cpufreq thermal reduction algorithm in the ACPI
           processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
           Bergmann)
      
         - Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)
      
         - Switch over ACPI to using a threaded interrupt handler for the SCI
           (Rafael J. Wysocki)
      
         - Allow ACPI Notify () handlers to run on all CPUs and clean up the
           ACPI interface for deferred events processing (Rafael J. Wysocki)
      
         - Switch over the ACPI EC driver to using a threaded handler for the
           dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)
      
         - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
           to keep local interrupts on (Rafael J. Wysocki)
      
         - Adjust the USB4 _OSC handshake to correctly handle cases in which
           certain types of OS control are denied by the platform (Mika
           Westerberg)
      
         - Correct and clean up the generic function for parsing ACPI
           data-only tables with array structure (Yuntao Wang)
      
         - Modify acpi_dev_uid_match() to support different types of its
           second argument and adjust its users accordingly (Raag Jadav)
      
         - Clean up code related to acpi_evaluate_reference() and ACPI device
           lists (Rafael J. Wysocki)
      
         - Use generic ACPI helpers for evaluating trip point temperature
           objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
           Bergmann)
      
         - Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
           zone driver (Jeff Brasen)
      
         - Modify the ACPI LPIT table handling code to avoid u32
           multiplication overflows in state residency computations (Nikita
           Kiryushin)
      
         - Drop an unused helper function from the ACPI backlight (video)
           driver and add a clarifying comment to it (Hans de Goede)
      
         - Update the ACPI backlight driver to avoid using uninitialized
           memory in some cases (Nikita Kiryushin)
      
         - Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo
           Qiu)
      
         - Add support for vendor-defined error types to the ACPI APEI error
           injection code (Avadhut Naik)
      
         - Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous
           memory failure events, so they are handled differently from the
           asynchronous ones (Shuai Xue)
      
         - Fix NULL pointer dereference check in the ACPI extlog driver
           (Prarit Bhargava)
      
         - Adjust the ACPI extlog driver to clear the Extended Error Log
           status when RAS_CEC handled the error (Tony Luck)
      
         - Add IRQ override quirks for some Infinity laptops and for TongFang
           GMxXGxx (David McFarland, Hans de Goede)
      
         - Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is
           not the same as one of the real pxm values (Yuntao Wang)
      
         - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
           driver so as to prevent miscalculation of the values in the clock
           divider (Andy Shevchenko)
      
         - Adjust comments in the ACPI watchdog driver to prevent kernel-doc
           from complaining during documentation builds (Randy Dunlap)
      
         - Make the ACPI button driver send wakeup key events to user space in
           addition to power button events on systems that can be woken up by
           the power button (Ken Xue)
      
         - Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
           structure field (Dmitry Antipov)"

       "MTD:
      
         - Apart from preventing the mtdblk to run on top of ftl or ubiblk
           (which may cause security issues and has no meaning anyway), there
           are a few misc fixes.
      
        Raw NAND:
      
         - Two meaningful changes this time. The conversion of the brcmnand
           driver to the ->exec_op() API, this series brought additional
           changes to the core in order to help controller drivers to handle
           themselves the WP pin during destructive operations when relevant.
      
         - There is also a series bringing important fixes to the sequential
           read feature.
      
         - As always, there is as well a whole bunch of miscellaneous W=1
           fixes, together with a few runtime fixes (double free, timeout
           value, OOB layout, missing register initialization) and the usual
           load of remove callbacks turned into void (which led to switch the
           txx9ndfmc driver to use module_platform_driver()).
      
        SPI NOR:
      
         - SPI NOR comes with die erase support for multi die flashes, with
           new octal protocols (1-1-8 and 1-8-8) parsed from SFDP and with an
           updated documentation about what the contributors shall consider
           when proposing flash additions or updates.
      
         - Michael Walle stepped out from the reviewer role to maintainer"

           submitting messages while in atomic context in the process.
      
         - Many drivers were converted to use new APIs which avoid outdated

      Pull regulator updates from Mark Brown:
       "The main updates for this release are around monitoring of regulators,
        largely for error handling purposes. We allow the stream of regulator
        events to be seen by userspace as netlink events and allow system
        integrators to describe individual regulators as system critical with
        information on how long the system is expected to last on error. The
        system level error handling is very much about best effort problem
        mitigation rather than providing something fully robust, the initial
        drive was to provide a mechanism for trying to avoid initiating any
        new writes to flash once we notice the power going out.
      
        Otherwise it's very quiet, mainly several new Qualcomm devices.
      
         - Support for marking regulators as system critical and providing
           information on how long the system might last with those regulators
           in a failure state, hooked into the existing critical shutdown
           error handling.
      
         - Optional support for generating netlink events for events, there
           are use cases for system monitoring UIs and error handling.
      
         - A command line option to leave unused controllable regulators
           enabled, useful for debugging. We already only disable regulators
           we were explicitly given permission to control.

      Linus Torvalds authored
      Pull security module updates from Paul Moore:
      
       - Add three new syscalls: lsm_list_modules(), lsm_get_self_attr(), and
         lsm_set_self_attr().
      
         The first syscall simply lists the LSMs enabled, while the second and
         third get and set the current process' LSM attributes. Yes, these
         syscalls may provide similar functionality to what can be found under
         /proc or /sys, but they were designed to support multiple,
         simultaneaous (stacked) LSMs from the start as opposed to the current
         /proc based solutions which were created at a time when only one LSM
         was allowed to be active at a given time.
      
         We have spent considerable time discussing ways to extend the
         existing /proc interfaces to support multiple, simultaneaous LSMs and
         even our best ideas have been far too ugly to support as a kernel
         API; after +20 years in the kernel, I felt the LSM layer had
         established itself enough to justify a handful of syscalls.
      
         Support amongst the individual LSM developers has been nearly
         unanimous, with a single objection coming from Tetsuo (TOMOYO) as he
         is worried that the LSM_ID_XXX token concept will make it more
         difficult for out-of-tree LSMs to survive. Several members of the LSM
         community have demonstrated the ability for out-of-tree LSMs to
         continue to exist by picking high/unused LSM_ID values as well as
         pointing out that many kernel APIs rely on integer identifiers, e.g.
         syscalls (!), but unfortunately Tetsuo's objections remain.
      
         My personal opinion is that while I have no interest in penalizing
         out-of-tree LSMs, I'm not going to penalize in-tree development to
         support out-of-tree development, and I view this as a necessary step
         forward to support the push for expanded LSM stacking and reduce our
         reliance on /proc and /sys which has occassionally been problematic
         for some container users. Finally, we have included the linux-api
         folks on (all?) recent revisions of the patchset and addressed all of
         their concerns.
      
       - Add a new security_file_ioctl_compat() LSM hook to handle the 32-bit
         ioctls on 64-bit systems problem.
      
         This patch includes support for all of the existing LSMs which
         provide ioctl hooks, although it turns out only SELinux actually
         cares about the individual ioctls. It is worth noting that while
         Casey (Smack) and Tetsuo (TOMOYO) did not give explicit ACKs to this
         patch, they did both indicate they are okay with the changes.
      
       - Fix a potential memory leak in the CALIPSO code when IPv6 is disabled
         at boot.
      
         While it's good that we are fixing this, I doubt this is something
         users are seeing in the wild as you need to both disable IPv6 and
         then attempt to configure IPv6 labeled networking via
         NetLabel/CALIPSO; that just doesn't make much sense.
      
         Normally this would go through netdev, but Jakub asked me to take
         this patch and of all the trees I maintain, the LSM tree seemed like
         the best fit.
      
       - Update the LSM MAINTAINERS entry with additional information about
         our process docs, patchwork, bug reporting, etc.
      
         I also noticed that the Lockdown LSM is missing a dedicated
         MAINTAINERS entry so I've added that to the pull request. I've been
         working with one of the major Lockdown authors/contributors to see if
         they are willing to step up and assume a Lockdown maintainer role;
         hopefully that will happen soon, but in the meantime I'll continue to
         look after it.

      Pull selinux updates from Paul Moore:
      
       - Add a new SELinux initial SID, SECINITSID_INIT, to represent
         userspace processes started before the SELinux policy is loaded in
         early boot.
      
         Prior to this patch all processes were marked as SECINITSID_KERNEL
         before the SELinux policy was loaded, making it difficult to
         distinquish early boot userspace processes from the kernel in the
         SELinux policy.
      
         For most users this will be a non-issue as the policy is loaded early
         enough during boot, but for users who load their SELinux policy
         relatively late, this should make it easier to construct meaningful
         security policies.
      
       - Cleanups to the selinuxfs code by Al, mostly on VFS related issues
         during a policy reload.
      
         The commit description has more detail, but the quick summary is that
         we are replacing a disconnected directory approach with a temporary
         directory that we swapover at the end of the reload.
      
       - Fix an issue where the input sanity checking on socket bind()
         operations was slightly different depending on the presence of
         SELinux.
      
         This is caused by the placement of the LSM hooks in the generic
         socket layer as opposed to the protocol specific bind() handler where
         the protocol specific sanity checks are performed. Mickaël has
         mentioned that he is working to fix this, but in the meantime we just
         ensure that we are replicating the checks properly.
      
         We need to balance the placement of the LSM hooks with the number of
         LSM hooks; pushing the hooks down into the protocol layers is likely
         not the right answer.
      
       - Update the avc_has_perm_noaudit() prototype to better match the
         function definition.
      
       - Migrate from using partial_name_hash() to full_name_hash() the
         filename transition hash table.
      
         This improves the quality of the code and has the potential for a
         minor performance bump.
      
       - Consolidate some open coded SELinux access vector comparisions into a
         single new function, avtab_node_cmp(), and use that instead.
      
         A small, but nice win for code quality and maintainability.
      
       - Updated the SELinux MAINTAINERS entry with additional information
         around process, bug reporting, etc.
      
         We're also updating some of our "official" roles: dropping Eric Paris
         and adding Ondrej as a reviewer.
      
       - Cleanup the coding style crimes in security/selinux/include.
      
         While I'm not a fan of code churn, I am pushing for more automated
         code checks that can be done at the developer level and one of the
         obvious things to check for is coding style.
      
         In an effort to start from a "good" base I'm slowly working through
         our source files cleaning them up with the help of clang-format and
         good ol' fashioned human eyeballs; this has the first batch of these
         changes.
      
         I've been splitting the changes up per-file to help reduce the impact
         if backports are required (either for LTS or distro kernels), and I
         expect the some of the larger files, e.g. hooks.c and ss/services.c,
         will likely need to be split even further.
      
       - Cleanup old, outdated comments.

       "The audit updates are fairly minor with only two patches:
      
         - Send an audit ACK to userspace immediately upon receiving an auditd
           registration event as opposed to waiting until the registration has
           been fully processed and the audit backlog starts filling the
           netlink buffers.
      
           Sending the ACK earlier, as done here, is still safe as the
           operation should not fail at the point when the ACK is done, and
           doing so helps avoid the ACK being dropped in extreme situations.
      
         - Update the audit MAINTAINERS entry with additional information.
      
           There isn't anything in this update that should be new to regular
           contributors or list subscribers, but I'm pushing to start
           documenting our processes, conventions, etc. and this seems like an
           important part of that"

      Pull slab updates from Vlastimil Babka:
      
       - SLUB: delayed freezing of CPU partial slabs (Chengming Zhou)
      
         Freezing is an operation involving double_cmpxchg() that makes a slab
         exclusive for a particular CPU. Chengming noticed that we use it also
         in situations where we are not yet installing the slab as the CPU
         slab, because freezing also indicates that the slab is not on the
         shared list. This results in redundant freeze/unfreeze operation and
         can be avoided by marking separately the shared list presence by
         reusing the PG_workingset flag.
      
         This approach neatly avoids the issues described in 9b1ea29b
         ("Revert "mm, slub: consider rest of partial list if acquire_slab()
         fails"") as we can now grab a slab from the shared list in a quick
         and guaranteed way without the cmpxchg_double() operation that
         amplifies the lock contention and can fail.
      
         As a result, lkp has reported 34.2% improvement of
         stress-ng.rawudp.ops_per_sec
      
       - SLAB removal and SLUB cleanups (Vlastimil Babka)
      
         The SLAB allocator has been deprecated since 6.5 and nobody has
         objected so far. We agreed at LSF/MM to wait until the next LTS,
         which is 6.6, so we should be good to go now.
      
         This doesn't yet erase all traces of SLAB outside of mm/ so some dead
         code, comments or documentation remain, and will be cleaned up
         gradually (some series are already in the works).
      
         Removing the choice of allocators has already allowed to simplify and
         optimize the code wiring up the kmalloc APIs to the SLUB
         implementation.

      Pull cgroup updates from Tejun Heo:
      
       - Yafang Shao added task_get_cgroup1() helper to enable a similar BPF
         helper so that BPF progs can be more useful on cgroup1 hierarchies.
         While cgroup1 is mostly in maintenance mode, this addition is very
         small while having an outsized usefulness for users who are still on
         cgroup1. Yafang also optimized root cgroup list access by making it
         RCU protected in the process.
      
       - Waiman Long optimized rstat operation leading to substantially lower
         and more consistent lock hold time while flushing the hierarchical
         statistics. As the lock can be acquired briefly in various hot paths,
         this reduction has cascading benefits.
      
       - Waiman also improved the quality of isolation for cpuset's isolated
         partitions. CPUs which are allocated to isolated partitions are now
         excluded from running unbound work items and cpu_is_isolated() test
         which is used by vmstat and memcg to reduce interference now includes
         cpuset isolated CPUs. While it isn't there yet, the hope is
         eventually reaching parity with the isolation level provided by the

      arm64: Update __NR_compat_syscalls for statmount/listmount · f0a78b3e
      Florian Fainelli authored
      Commit d8b0f546 ("wire up syscalls for statmount/listmount") added
      two new system calls to arch/arm64/include/asm/unistd32.h but forgot to
      update the __NR_compat_syscalls number, thus causing the following build
      failures:
      
        arch/arm64/include/asm/unistd32.h:922:24: error: array index in initializer exceeds array bounds
          922 | #define __NR_statmount 457
              |                        ^~~
        arch/arm64/kernel/sys32.c:130:34: note: in definition of macro '__SYSCALL'
          130 | #define __SYSCALL(nr, sym)      [nr] = __arm64_##sym,
              |                                  ^~
      
      Bump up the number by two to accomodate for the new system calls added.
