48dc810012 - Split dm-bufio's rw_semaphore and rbtree. Offers improvements to 
dm-bufio's locking to allow increased concurrent IO -- particularly
   for read access for buffers already in dm-bufio's cache.
 
 - Also split dm-bio-prison-v1's spinlock and rbtree with comparable
   aim at improving concurrent IO (for the DM thinp target).
 
 - Both the dm-bufio and dm-bio-prison-v1 scaling of the number of
   locks and rbtrees used are managed by dm_num_hash_locks(). And the
   hash function used by both is dm_hash_locks_index().
 
 - Allow DM targets to require DISCARD, WRITE_ZEROES and SECURE_ERASE
   to be split at the target specified boundary (in terms of
   max_discard_sectors, max_write_zeroes_sectors and
   max_secure_erase_sectors respectively).
 
 - DM verity error handling fix for check_at_most_once on FEC.
 
 - Update DM verity target to emit audit events on verification failure
   and more.
 
 - DM core ->io_hints improvements needed in support of new discard
   support that is added to the DM "zero" and "error" targets.
 
 - Fix missing kmem_cache_destroy() call in initialization error path
   of both the DM integrity and DM clone targets.
 
 - A couple fixes for DM flakey, also add "error_reads" feature.
 
 - Fix DM core's resume to not lock FS when the DM map is NULL;
   otherwise initial table load can race with FS mount that takes
   superblock's ->s_umount rw_semaphore.
 
 - Various small improvements to both DM core and DM targets.

Pull io_uring updates from Jens Axboe:

 - Cleanup of the io-wq per-node mapping, notably getting rid of it so
   we just have a single io_wq entry per ring (Breno)

 - Followup to the above, move accounting to io_wq as well and
   completely drop struct io_wqe (Gabriel)

 - Enable KASAN for the internal io_uring caches (Breno)

 - Add support for multishot timeouts. Some applications use timeouts to
   wake someone waiting on completion entries, and this makes it a bit
   easier to just have a recurring timer rather than needing to rearm it
   every time (David)

 - Support archs that have shared cache coloring between userspace and
   the kernel, and hence have strict address requirements for mmap'ing
   the ring into userspace. This should only be parisc/hppa. (Helge, me)

 - XFS has supported O_DIRECT writes without needing to lock the inode
   exclusively for a long time, and ext4 now supports it as well. This
   is true for the common cases of not extending the file size. Flag the
   fs as having that feature, and utilize that to avoid serializing
   those writes in io_uring (me)

 - Enable completion batching for uring commands (me)

 - Revert patch adding io_uring restriction to what can be GUP mapped or
   not. This does not belong in io_uring, as io_uring isn't really
   special in this regard. Since this is also getting in the way of
   cleanups and improvements to the GUP code, get rid of if (me)

 - A few series greatly reducing the complexity of registered resources,
   like buffers or files. Not only does this clean up the code a lot,
   the simplified code is also a LOT more efficient (Pavel)

 - Series optimizing how we wait for events and run task_work related to
   it (Pavel)

 - Fixes for file/buffer unregistration with DEFER_TASKRUN (Pavel)

 - Misc cleanups and improvements (Pavel, me)

5c7ecada25 f2fs update for 6.4-rc1 
In this round, we've mainly modified to support non-power-of-two zone size,
 which is not required for f2fs by design. In order to avoid arch dependency,
 we refactored the messy rb_entry structure shared across different extent_cache.
 In addition to the improvement, we've also fixed several subtle bugs and
 error cases.
 
 Enhancement:
 - support non-power-of-two zone size for zoned device
 - remove sharing the rb_entry structure in extent cache
 - refactor f2fs_gc to call checkpoint in urgent condition
 - support iopoll
 
 Bug fix:
 - fix potential corruption when moving a directory
 - fix to avoid use-after-free for cached IPU bio
 - fix the folio private usage
 - avoid kernel warnings or panics in the cp_error case
 - fix to recover quota data correctly
 - fix some bugs in atomic operations
 - fix system crash due to lack of free space in LFS
 - fix null pointer panic in tracepoint in __replace_atomic_write_block
 - fix iostat lock protection
 - fix scheduling while atomic in decompression path
 - preserve direct write semantics when buffering is forced
 - fix to call f2fs_wait_on_page_writeback() in f2fs_write_raw_pages()

fbfaf03eba dlm for 6.4 
Remove some unused features (related to lock timeouts) that have been
 previously scheduled for removal.
 
 Fix a bug where the pending callback flag would be incorrectly cleared,
 which could potentially result in missing a completion callback.
 
 Use an unbound workqueue for dlm socket handling so that socket
 operations can be processed with less delay.
 
 Fix possible lockspace join connection errors with large clusters (e.g.
 over 16 nodes) caused by a small socket backlog setting.
 
 Use atomic bit ops for internal flags to help avoid mistakes copying
 flag values from messages.
 
 Fix recently introduced bug where memory for lvb data could be
 unnecessarily allocated for a lock.

Pull btrfs updates from David Sterba:
 "Mostly core changes and cleanups, some notable fixes and two
  performance improvements in directory logging.

  The IO path cleanups are removing or refactoring old code, scrub main
  loop has been completely rewritten also refactoring old code.

  There are some changes to non-btrfs code, mostly trivial, the cgroup
  punt bio logic is only moved from generic code.

  Performance improvements:

   - improve logging changes in a directory during one transaction,
     avoid iterating over items and reduce lock contention (fsync time
     4x lower)

   - when logging directory entries during one transaction, reduce
     locking of subvolume trees by checking tree-log instead
     (improvement in throughput and latency for concurrent access to a
     subvolume)

  Notable fixes:

   - dev-replace:
      - properly honor read mode when requested to avoid reading from
        source device
      - target device won't be used for eventual read repair, this is
        unreliable for NODATASUM files
      - when there are unpaired (and unrepairable) metadata during
        replace, exit early with error and don't try to finish whole
        operation

   - scrub ioctl properly rejects unknown flags

   - fix global block reserve calculations

   - fix partial direct io write when there's a page fault in the
     middle, iomap will try to continue with partial request but the
     btrfs part did not match that, this can lead to zeros written
     instead of data

  Core changes:

   - io path:
      - continued cleanups and refactoring around bio handling
      - extent io submit path simplifications and cleanups
      - flush write path simplifications and cleanups
      - rework logic of passing sync mode of bio, with further cleanups

   - rewrite scrub code flow, restructure how the stripes are enumerated
     and verified in a more unified way

   - allow to set lower threshold for block group reclaim in debug mode
     to aid zoned mode testing

   - remove obsolete time-based delayed ref throttling logic when
     truncating items

   - DREW locks are not using percpu variables anymore

   - more warning fixes (-Wmaybe-uninitialized)

   - u64 division simplifications

   - error handling improvements

  Non-btrfs code changes:

   - push cgroup punt bio logic to btrfs code (there was no other user
     of that), the functionality can be now selected separately by
     BLK_CGROUP_PUNT_BIO

   - crc32c_impl removed after removing last uses in btrfs code

   - add btrfs_assertfail() to objtool table"

* tag 'for-6.4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (147 commits)
  btrfs: mark btrfs_assertfail() __noreturn
  btrfs: fix uninitialized variable warnings

  btrfs: avoid iterating over all indexes when logging directory

9b78d91963 net: phy: hide the PHYLIB_LEDS knob 
commit 4bb7aac70b ("net: phy: fix circular LEDS_CLASS dependencies")
solved a build failure, but introduces a new config knob with a default
'y' value: PHYLIB_LEDS.

The latter is against the current new config policy. The exception
was raised to allow the user to catch bad configurations without led
support.

Anyway the current definition of PHYLIB_LEDS does not fit the above
goal: if LEDS_CLASS is disabled, the new config will be available
only with PHYLIB disabled, too.

Hide the mentioned config, to preserve the randconfig testing done so
far, while respecting the mentioned policy.

3361e9a4ea remoteproc updates for v6.4 
Unnecessary type casts from the void * rproc->priv pointer is dropped
 throughout te subsystem.
 
 A kernel-doc error is corrected in the Mediatek SCPI IPI implementation.
 
 The firmware loading onto the IMX DSP remote processors is reworked to
 avoid non-32bit memory operations. A module parameter is introduced to
 assist development of firmware without communication abilities in place.
 Error paths in imx_dsp_rproc_mbox_alloc() is cleaned up.
 
 The cluster configuration handling in the TI K3 R5 driver is corrected
 and support for the single-R5 core found in the TI AM62x SoC family is
 introduced.
 
 The TI PRU driver device- to virtual-address translation is updated to
 avoid compiler warning about the unsigned device-address always being
 larger than 0.
 
 The ST remoteproc driver is transitioned to use of_property_present().
 
 Issues with kicks arriving after the STM32 remote processor has been
 shut down are mitigated by checking the processor's state before
 handling them.
 
 Support for mailbox channels for communication with the remote
 processors are added to the Xilinx R5 remoteproc driver. The naming of
 carveouts are corrected and their parsing is reworked.
 For this a couple of fixes targeting the mailbox subsystem are picked up
 here as well.
 
 Reference counting of of_nodes are corrected in the ST, STM32, RCAR and
 IMX remoteproc drivers.

f5468bec21 regmap: Updates for v6.4 
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.
 
  - 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.

Pull slab updates from Vlastimil Babka:
 "The main change is naturally the SLOB removal. Since its deprecation
  in 6.2 I've seen no complaints so hopefully SLUB_(TINY) works well for
  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
  from Thomas, Thorsten and Vernon"

* tag 'slab-for-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab:
  mm/slab: document kfree() as allowed for kmem_cache_alloc() objects

d53c3eaaef ARM: SoC devicetree changes for 6.4 
The devicetree changes overall are again dominated by the Qualcomm
 Snapdragon platform that weighs in at over 300 changesets, but there
 are many updates across other platforms as well, notably Mediatek, NXP,
 Rockchips, Renesas, TI, Samsung and ST Microelectronics. These all
 add new features for existing machines, as well as new machines and
 SoCs.
 
 The newly added SoCs are:
 
  - Allwinner T113-s, an Cortex-A7 based variant of the RISC-V
    based D1 chip.
 
  - StarFive JH7110, a RISC-V SoC based on the Sifive U74 core
    like its JH7100 predecessor, but with additional CPU cores
    and a GPU.
 
  - Apple M2 as used in current Macbook Air/Pro and Mac Mini
    gets added, with comparable support as its M1 predecessor.
 
  - Unisoc UMS512 (Tiger T610) is a midrange smartphone SoC
 
  - Qualcomm IPQ5332 and IPQ9574 are Wi-Fi 7 networking SoCs,
    based on the Cortex-A53 and Cortex-A73 cores, respectively.
 
  - Qualcomm sa8775p is an automotive SoC derived from the
    Snapdragon family.
 
 Including the initial board support for the added SoC platforms,
 there are 52 new machines. The largest group are 19 boards
 industrial embedded boards based on the NXP i.MX6 (32-bit)
 and i.MX8 (64-bit) families.
 
 Others include:
 
  - Two boards based on the Allwinner f1c200s ultra-low-cost chip
 
  - Three "Banana Pi" variants based on the Amlogic g12b
    (A311D, S922X) SoC.
 
  - The Gl.Inet mv1000 router based on Marvell Armada 3720
 
  - A Wifi/LTE Dongle based on Qualcomm msm8916
 
  - Two robotics boards based on Qualcomm QRB chips
 
  - Three Snapdragon based phones made by Xiaomi
 
  - Five developments boards based on various Rockchip SoCs,
    including the rk3588s-khadas-edge2 and a few NanoPi
    models
 
  - The AM625 Beagleplay industrial SBC
 
 Another 14 machines get removed: both boards for the obsolete "oxnas"
 platform, three boards for the Renesas r8a77950 SoC that were only for
 pre-production chips, and various chromebook models based on the Qualcomm
 Sc7180 "trogdor" design that were never part of products.

18032df5ef ARM: SoC changes for 6.4 
The Oxford Semiconductor OX810/OX820 "oxnas" platform gets retired
 after the ARM11MPcore processor keeps causing problems in certain corner
 cases. OX820 was the only remaining SoC with this core after CNS3xxx got
 retired, and its driver support for never completely merged upstream. The
 Arm "Realview" reference platform still supports ARM11MPCore in principle,
 but this was never a product, and the CPU support will get cleaned up
 later on.
 
 Another series updates the mv78xx0 platform, which has been similarly
 neglected for a while, but should work properly again now.
 
 The other changes are minor cleanups across platforms, mostly converting
 code to more modern interfaces for DT nodes and removing some more code
 as a follow-up to the large-scale platform removal in linux-6.3.

de10553fce x86 APIC updates: 
- 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

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.

e7989789c6 Timers and timekeeping updates: 
- Improve the VDSO build time checks to cover all dynamic relocations
 
     VDSO does not allow dynamic relcations, 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 task
    hold it accross the expiry function and let the deleting task which
    waits for the expiry to complete block on the mutex.
 
    In the non-contended case this results in an extra mutex_lock()/unlock()
    pair on both sides.
 
    This avoids spin-waiting on a task which is scheduled out, prevents the
    livelock and cures the problem for RT and !RT systems.

29e95a4b26 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.
