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

 - several fixes and enhancements to attribute feature

 - changes to reorganize deferred action function introducing
   KUNIT_DEFINE_ACTION_WRAPPER

 - new feature adds ability to run tests after boot using debugfs

 - fixes and enhancements to string-stream-test:
     - parse ERR_PTR in string_stream_destroy()
     - unchecked dereference in bug fix in debugfs_print_results()

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:

   - Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs
     to the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui)

   - Do not enable interrupts when entering idle in the haltpoll cpuidle
     driver (Borislav Petkov)

     CLEMENT)

   - Rework trans_stat_show() in the devfreq core code to avoid buffer
     overflows (Christian Marangi)

   - Synchronize devfreq_monitor_[start/stop] so as to prevent a timer
     list corruption from occurring when devfreq governors are switched
     frequently (Mukesh Ojha)

   - Fix possible deadlocks in the core system-wide PM code that occur
     if device-handling functions cannot be executed asynchronously
     during resume from system-wide suspend (Rafael J. Wysocki)

   - Clean up unnecessary local variable initializations in multiple
     places in the hibernation code (Wang chaodong, Li zeming)

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:

   - Add dynamic thresholds for trip point crossing detection to prevent
     trip point crossing notifications from being sent at incorrect
     times or not at all in some cases (Rafael J. Wysocki)

   - Fix synchronization issues related to the resume of thermal zones
     during a system-wide resume and allow thermal zones to be resumed
     concurrently (Rafael J. Wysocki)

   - 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)

   - Make the IPA thermal governor handle thermal instance weight
     changes via sysfs correctly (Lukasz Luba)

   - Update the thermal netlink code to avoid sending messages if there
     are no recipients (Stanislaw Gruszka)

   - Fix compilation warning in the tmon utility (Florian Eckert)

   - Add support for interrupt-based thermal configuration on Exynos

     the last CPU in it goes offline (Ricardo Neri)

   - Fix a kernel-doc warning and a spello in the cpuidle_cooling
     thermal driver (Randy Dunlap)

   - Move the .get_temp() thermal zone callback presence check to the

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

   - 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

   - 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

  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's a few patches for other trees, API updates to allow the

  touched a controller embedded in the USB code.

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.

   - Support for Quacomm MP5496, PM8010 and PM8937"

Pull integrity updates from Mimi Zohar:

 - Add a new IMA/EVM maintainer and reviewer

 - Disable EVM on overlayfs

   The EVM HMAC and the original file signatures contain filesystem
   specific metadata (e.g. i_ino, i_generation and s_uuid), preventing
   the security.evm xattr from directly being copied up to the overlay.
   Further before calculating and writing out the overlay file's EVM
   HMAC, EVM must first verify the existing backing file's
   'security.evm' value.

   For now until a solution is developed, disable EVM on overlayfs.

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.

Pull audit updates from Paul Moore:
 "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

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
   `isolcpus` boot param but in a dynamic manner.

Pull scheduler updates from Ingo Molnar:
 "Energy scheduling:

   - Consolidate how the max compute capacity is used in the scheduler
     and how we calculate the frequency for a level of utilization.

   - Rework interface between the scheduler and the schedutil governor

   - Simplify the util_est logic

  Deadline scheduler:

   - Work more towards reducing SCHED_DEADLINE starvation of low
     priority tasks (e.g., SCHED_OTHER) tasks when higher priority tasks
     monopolize CPU cycles, via the introduction of 'deadline servers'
     (nested/2-level scheduling).

     "Fair servers" to make use of this facility are not introduced yet.

  EEVDF:

   - Introduce O(1) fastpath for EEVDF task selection

  NUMA balancing:

   - Tune the NUMA-balancing vma scanning logic some more, to better
     distribute the probability of a particular vma getting scanned.

  Plus misc fixes, cleanups and updates"

failures:
