Pull regmap updates from Mark Brown:
 "This is a much bigger change for regmap than is normal, the main
  things being the addition of some KUnit coverage and a maple tree
  based register cache which longer term is likely to replace the rbtree
  cache except possibly for very small register maps.

  While it's complete overkill for most applications the code for maple
  trees is there and there are some larger, sparser devices where the
  data structure is a better fit.

  The maple tree support is still a work in progress but already useful,
  there's some conversions of drivers ready to go after the merge
  window.

  Summary:

   - Support for shifting register addresses up as well as down, there's
     a use cases with memory mapped MDIO.

   - Refactoring of the type configuration in regmap-irq to allow access
     to driver data in the handler, needed by some GPIO devices.

   - Some initial KUnit coverage, the bulk of the driver facing API is
     covered but there's holes and things like the data marshalling for
     bytestream buses are just not covered in the slightest.

   - Removal of the compressed cache type, it had zero users and was
     getting in the way of KUnit.

   - Addition of a maple tree based register cache, there's more work to
     do but it's already useful for some devices with a flatter data
     structure than rbtree and getting to use all the optimisation work
     Liam is doing"

 "The main change is naturally the SLOB removal. Since its deprecation

  everyone and we can proceed.

  Besides the code cleanup, the main immediate benefit will be allowing
  kfree() family of function to work on kmem_cache_alloc() objects,
  which was incompatible with SLOB. This includes kfree_rcu() which had
  no kmem_cache_free_rcu() counterpart yet and now it shouldn't be
  necessary anymore.

  Besides that, there are several small code and comment improvements

Pull x86 APIC updates from Thomas Gleixner:

 - Fix the incorrect handling of atomic offset updates in
   reserve_eilvt_offset()

   The check for the return value of atomic_cmpxchg() is not compared
   against the old value, it is compared against the new value, which
   makes it two round on success.

   Convert it to atomic_try_cmpxchg() which does the right thing.

 - Handle IO/APIC less systems correctly

   When IO/APIC is not advertised by ACPI then the computation of the
   lower bound for dynamically allocated interrupts like MSI goes wrong.

   This lower bound is used to exclude the IO/APIC legacy GSI space as
   that must stay reserved for the legacy interrupts.

   In case that the system, e.g. VM, does not advertise an IO/APIC the
   lower bound stays at 0.

   0 is an invalid interrupt number except for the legacy timer
   interrupt on x86. The return value is unchecked in the core code, so
   it ends up to allocate interrupt number 0 which is subsequently
   considered to be invalid by the caller, e.g. the MSI allocation code.

   A similar problem was already cured for device tree based systems
   years ago, but that missed - or did not envision - the zero IO/APIC
   case.

   Consolidate the zero check and return the provided "from" argument to
   the core code call site, which is guaranteed to be greater than 0.

 - Simplify the X2APIC cluster CPU mask logic for CPU hotplug

   Per cluster CPU masks are required for X2APIC in cluster mode to
   determine the correct cluster for a target CPU when calculating the
   destination for IPIs

   These masks are established when CPUs are borught up. The first CPU
   in a cluster must allocate a new cluster CPU mask. As this happens
   during the early startup of a CPU, where memory allocations cannot be
   done, the mask has to be allocated by the control CPU.

   The current implementation allocates a clustermask just in case and
   if the to be brought up CPU is the first in a cluster the CPU takes
   over this allocation from a global pointer.

   This works nicely in the fully serialized CPU bringup scenario which
   is used today, but would fail completely for parallel bringup of
   CPUs.

   The cluster association of a CPU can be computed from the APIC ID
   which is enumerated by ACPI/MADT.

   So the cluster CPU masks can be preallocated and associated upfront
   and the upcoming CPUs just need to set their corresponding bit.

   Aside of preparing for parallel bringup this is a valuable
   simplification on its own.

 - Remove global variables which control the early startup of secondary
   CPUs on 64-bit

   The only information which is needed by a starting CPU is the Linux
   CPU number. The CPU number allows it to retrieve the rest of the
   required data from already existing per CPU storage.

   So instead of initial_stack, early_gdt_desciptor and initial_gs
   provide a new variable smpboot_control which contains the Linux CPU
   number for now. The starting CPU can retrieve and compute all
   required information for startup from there.

   Aside of being a cleanup, this is also preparing for parallel CPU
   bringup, where starting CPUs will look up their Linux CPU number via
   the APIC ID, when smpboot_control has the corresponding control bit
   set.

 - Make cc_vendor globally accesible

   Subsequent parallel bringup changes require access to cc_vendor
   because confidental computing platforms need special treatment in the
   early startup phase vs. CPUID and APCI ID readouts.

   The change makes cc_vendor global and provides stub accessors in case
   that CONFIG_ARCH_HAS_CC_PLATFORM is not set.

   This was merged from the x86/cc branch in anticipation of further
   parallel bringup commits which require access to cc_vendor. Due to
   late discoveries of fundamental issue with those patches these
   commits never happened.

   The merge commit is unfortunately in the middle of the APIC commits
   so unraveling it would have required a rebase or revert. As the
   parallel bringup seems to be well on its way for 6.5 this would be
   just pointless churn. As the commit does not contain any functional
   change it's not a risk to keep it.

Pull timers and timekeeping updates from Thomas Gleixner:

 - Improve the VDSO build time checks to cover all dynamic relocations

   VDSO does not allow dynamic relocations, but the build time check is
   incomplete and fragile.

   It's based on architectures specifying the relocation types to search
   for and does not handle R_*_NONE relocation entries correctly.
   R_*_NONE relocations are injected by some GNU ld variants if they
   fail to determine the exact .rel[a]/dyn_size to cover trailing zeros.
   R_*_NONE relocations must be ignored by dynamic loaders, so they
   should be ignored in the build time check too.

   Remove the architecture specific relocation types to check for and
   validate strictly that no other relocations than R_*_NONE end up in
   the VSDO .so file.

 - Prefer signal delivery to the current thread for
   CLOCK_PROCESS_CPUTIME_ID based posix-timers

   Such timers prefer to deliver the signal to the main thread of a
   process even if the context in which the timer expires is the current
   task. This has the downside that it might wake up an idle thread.

   As there is no requirement or guarantee that the signal has to be
   delivered to the main thread, avoid this by preferring the current
   task if it is part of the thread group which shares sighand.

   This not only avoids waking idle threads, it also distributes the
   signal delivery in case of multiple timers firing in the context of
   different threads close to each other better.

 - Align the tick period properly (again)

   For a long time the tick was starting at CLOCK_MONOTONIC zero, which
   allowed users space applications to either align with the tick or to
   place a periodic computation so that it does not interfere with the
   tick. The alignement of the tick period was more by chance than by
   intention as the tick is set up before a high resolution clocksource
   is installed, i.e. timekeeping is still tick based and the tick
   period advances from there.

   The early enablement of sched_clock() broke this alignement as the
   time accumulated by sched_clock() is taken into account when
   timekeeping is initialized. So the base value now(CLOCK_MONOTONIC) is
   not longer a multiple of tick periods, which breaks applications
   which relied on that behaviour.

   Cure this by aligning the tick starting point to the next multiple of
   tick periods, i.e 1000ms/CONFIG_HZ.

 - A set of NOHZ fixes and enhancements:

     * Cure the concurrent writer race for idle and IO sleeptime
       statistics

       The statitic values which are exposed via /proc/stat are updated
       from the CPU local idle exit and remotely by cpufreq, but that
       happens without any form of serialization. As a consequence
       sleeptimes can be accounted twice or worse.

       Prevent this by restricting the accumulation writeback to the CPU
       local idle exit and let the remote access compute the accumulated
       value.

     * Protect idle/iowait sleep time with a sequence count

       Reading idle/iowait sleep time, e.g. from /proc/stat, can race
       with idle exit updates. As a consequence the readout may result
       in random and potentially going backwards values.

       Protect this by a sequence count, which fixes the idle time
       statistics issue, but cannot fix the iowait time problem because
       iowait time accounting races with remote wake ups decrementing
       the remote runqueues nr_iowait counter. The latter is impossible
       to fix, so the only way to deal with that is to document it
       properly and to remove the assertion in the selftest which
       triggers occasionally due to that.

     * Restructure struct tick_sched for better cache layout

     * Some small cleanups and a better cache layout for struct
       tick_sched

 - Implement the missing timer_wait_running() callback for POSIX CPU
   timers

   For unknown reason the introduction of the timer_wait_running()
   callback missed to fixup posix CPU timers, which went unnoticed for
   almost four years.

   While initially only targeted to prevent livelocks between a timer
   deletion and the timer expiry function on PREEMPT_RT enabled kernels,
   it turned out that fixing this for mainline is not as trivial as just
   implementing a stub similar to the hrtimer/timer callbacks.

   The reason is that for CONFIG_POSIX_CPU_TIMERS_TASK_WORK enabled
   systems there is a livelock issue independent of RT.

   CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y moves the expiry of POSIX CPU
   timers out from hard interrupt context to task work, which is handled
   before returning to user space or to a VM. The expiry mechanism moves
   the expired timers to a stack local list head with sighand lock held.
   Once sighand is dropped the task can be preempted and a task which
   wants to delete a timer will spin-wait until the expiry task is
   scheduled back in. In the worst case this will end up in a livelock
   when the preempting task and the expiry task are pinned on the same
   CPU.

   The timer wheel has a timer_wait_running() mechanism for RT, which
   uses a per CPU timer-base expiry lock which is held by the expiry
   code and the task waiting for the timer function to complete blocks
   on that lock.

   This does not work in the same way for posix CPU timers as there is
   no timer base and expiry for process wide timers can run on any task
   belonging to that process, but the concept of waiting on an expiry
   lock can be used too in a slightly different way.

   Add a per task mutex to struct posix_cputimers_work, let the expiry

Pull core debugobjects update from Thomas Gleixner:
 "A single update to debugobjects:

  Prevent a race vs statically initialized objects. Such objects are
  usually not initialized via an init() function. They are special cased
  and detected on first use under the assumption that they are already
  correctly initialized via the static initializer.

  This works correctly unless there are two concurrent debug object
  operations on such an object.

  The first one detects that the object is not yet tracked and tries to
  establish a tracking object after dropping the debug objects hash
  bucket lock. The concurrent operation does the same. The one which
  wins the race ends up modifying the state of the object which makes
  the other one fail resulting in a bogus debug objects warning.

  Prevent this by making the detection of a static object and the
  allocation of a tracking object atomic under the hash bucket lock. So
  the first one to acquire the hash bucket lock will succeed and the
  second one will observe the correct tracking state.

  This race existed forever but was only exposed when the timer wheel
  code added a debug_object_assert_init() call outside of the timer base
  locked region. This replaced the previous warning about
  timer::function being NULL which had to be removed when the
  timer_shutdown() mechanics were added"

However, the value of ov5670->xvclk is left as-is and the other clock

Pull erofs updates from Gao Xiang:
 "In this cycle, sub-page block support for uncompressed files is

  4k-block images on arm64 with 16/64k pages. In addition, end users
  could also use this feature to build a manifest to directly refer to
  golden tar data.

  Besides, long xattr name prefix support is also introduced in this
  cycle to avoid too many xattrs with the same prefix (e.g. overlayfs
  xattrs). It's useful for erofs + overlayfs combination (like Composefs
  model): the image size is reduced by ~14% and runtime performance is
  also slightly improved.

  Others are random fixes and cleanups as usual.

  Summary:

   - Add sub-page block size support for uncompressed files

   - Support flattened block device for multi-blob images to be attached
     into virtual machines (including cloud servers) and bare metals
