  selector for windowed register ranges get out of sync with the
  hardware during a cache sync plus associated KUnit tests. This was
  reported just at the end of the release cycle and only in -next for a
  day prior to the merge window so it seemed better to hold off for now,

Pull gpio updates from Bartosz Golaszewski:
 "We don't have any new drivers. The loongson driver is getting extended
  with support for new models. There's a big refactor of gpio-pca953x
  and many small improvements to others.

  The GPIO code in the kernel has acquired a lot of cruft over the years
  as well as many abusers of the API across the kernel tree. This
  release cycle we have started a major cleanup and improvement effort
  that will most likely span several releases. We have started by
  converting external users of struct gpio_chip to accessing the wrapper
  around it - struct gpio_device. This is because the latter is
  reference counted while the former is removed when the provider is
  unbound. We also removed several instances of drivers accessing
  private GPIOLIB structures and including the private header from
  drivers/gpio/.

  To that end you'll see several commits aimed at different subsystems
  (acked by relevant maintainers) as well as two merges from the
  x86/platform tree.

  We'll then rework the locking in GPIOLIB which currently uses a big
  spinlock for many different things and could use becoming more
  fine-grained, especially as it doesn't even get the locking right.
  We'll also use SRCU for protecting the gpio_chip pointer against
  in-kernel hot-unplug crashes similar to what we saw triggered from
  user-space and fixed with semaphores in gpiolib-cdev. The core GPIOLIB
  is still vulnerable to these use-cases. I'm just mentioning the plans
  here, this is not part of this PR.

  You'll see some new instances of using __free(). We've added a
  gpio_device_put cleanup helper similar to the put_device one
  introduced by Peter Zijlstra and used it according to the preferred
  pattern except where it didn't make sense.

  GPIOLIB core:
   - provide interfaces allowing users to retrieve, manage and query the
     reference counted GPIO device instead of accessing the private
     gpio_chip structure
   - replace gpiochip_find() with gpio_device_find()
   - remove unused acpi_get_and_request_gpiod()
   - improve the ignore_interrupt functionality in GPIO ACPI
   - correct notifier return codes in gpiolib-of
   - unexport gpiod_set_transitory() as it's unused outside of core GPIO
     code
   - while there are still external users accessing struct gpio_chip,
     let's make gpiochip_get_desc() public so that they at least use the
     preferred helper
   - improve locking for lookup tables
   - annotate struct linereq with __counted_by
   - improve GPIOLIB docs
   - add an OF quirk for LED trigger sources

  Driver improvements:
   - convert all GPIO drivers with .remove() callbacks to using the new
     variant returning void instead of int
   - stop accessing the GPIOLIB private structures in gpio-mockup,
     i2c-mux-gpio, hte-tegra194, gpio-sim
   - use the recommended pattern for autofree variables in gpio-sim
   - add support for more models to gpio-loongson
   - use a notifier chain to notify other blocks about interrupts in
     gpio-eic-sprd instead of looking up GPIO devices on every interrupt
   - convert gpio-pca953x and gpio-fx6408 to using the maple tree regmap
     cache
   - don't include GPIOLIB internal headers in drivers which don't need
     them
   - move the ingenic NAND quirk into gpiolib-of
   - add an ignore interrupt quirk for Peaq C1010
   - drop static GPIO base from gpio-omap, gpio-f7188x
   - use the preferred device_get_match_data() function in drivers that
     still don't
   - refactor gpio-pca953x: switch to using DEFINE_SIMPLE_DEV_PM_OPS(),
     use cleanup helpers, use dev_err_probe() where it makes sense,
     fully convert to using devres and some other minor tweaks

  DT bindings:
   - add support for a new model to gpio-vf610 and update existing
     properties
   - add support for more loongson models
   - add missing support for imx models that are used but undocumented
   - convert bindings for Intel IXP4xx to schema

  Minor stuff:
   - deprecate gpio-mockup in favor of gpio-sim
   - include missing headers here and there
   - stop using gpiochip_find() in OMAP1 board files
   - minor tweaks in gpio-vf610, gpio-hisi
   - remove unneeded 'extern' specifiers from headers"

Pull networking updates from Jakub Kicinski:
 "Core & protocols:

   - Support usec resolution of TCP timestamps, enabled selectively by a
     route attribute.

   - Defer regular TCP ACK while processing socket backlog, try to send
     a cumulative ACK at the end. Increase single TCP flow performance
     on a 200Gbit NIC by 20% (100Gbit -> 120Gbit).

   - The Fair Queuing (FQ) packet scheduler:
       - add built-in 3 band prio / WRR scheduling
       - support bypass if the qdisc is mostly idle (5% speed up for TCP RR)
       - improve inactive flow reporting
       - optimize the layout of structures for better cache locality

   - Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern
     replacement for the old MD5 option.

   - Add more retransmission timeout (RTO) related statistics to
     TCP_INFO.

   - Support sending fragmented skbs over vsock sockets.

   - Make sure we send SIGPIPE for vsock sockets if socket was
     shutdown().

   - Add sysctl for ignoring lower limit on lifetime in Router
     Advertisement PIO, based on an in-progress IETF draft.

   - Add sysctl to control activation of TCP ping-pong mode.

   - Add sysctl to make connection timeout in MPTCP configurable.

   - Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps
     limit the number of wakeups.

   - Support netlink GET for MDB (multicast forwarding), allowing user
     space to request a single MDB entry instead of dumping the entire
     table.

   - Support selective FDB flushing in the VXLAN tunnel driver.

   - Allow limiting learned FDB entries in bridges, prevent OOM attacks.

   - Allow controlling via configfs netconsole targets which were
     created via the kernel cmdline at boot, rather than via configfs at
     runtime.

   - Support multiple PTP timestamp event queue readers with different
     filters.

   - MCTP over I3C.

  BPF:

   - Add new veth-like netdevice where BPF program defines the logic of
     the xmit routine. It can operate in L3 and L2 mode.

   - Support exceptions - allow asserting conditions which should never
     be true but are hard for the verifier to infer. With some extra
     flexibility around handling of the exit / failure:

          https://lwn.net/Articles/938435/

   - Add support for local per-cpu kptr, allow allocating and storing
     per-cpu objects in maps. Access to those objects operates on the
     value for the current CPU.

     This allows to deprecate local one-off implementations of per-CPU
     storage like BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps.

   - Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is
     for systemd to re-implement the LogNamespace feature which allows
     running multiple instances of systemd-journald to process the logs
     of different services.

   - Enable open-coded task_vma iteration, after maple tree conversion
     made it hard to directly walk VMAs in tracing programs.

     use cases is customizable OOM victim selection via BPF.

   - Allow source address selection with bpf_*_fib_lookup().

   - Add ability to pin BPF timer to the current CPU.

   - Prevent creation of infinite loops by combining tail calls and
     fentry/fexit programs.

  Changes to common code:

   - overflow: add DEFINE_FLEX() for on-stack definition of structs with
     flexible array members.

   - Process doc update with more guidance for reviewers.

  Driver API:

   - Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy
     mutex in most places and remove a lot of smaller locks.

   - Create a common DPLL configuration API. Allow configuring and
     querying state of PLL circuits used for clock syntonization, in
     network time distribution.

   - Unify fragmented and full page allocation APIs in page pool code.
     Let drivers be ignorant of PAGE_SIZE.

   - Rework PHY state machine to avoid races with calls to phy_stop().

   - Notify DSA drivers of MAC address changes on user ports, improve
     correctness of offloads which depend on matching port MAC
     addresses.

   - Allow antenna control on injected WiFi frames.

   - Reduce the number of variants of napi_schedule().

   - Simplify error handling when composing devlink health messages.

     This time around, due to how the kernel and Rust schedules have
     aligned, there are two upgrades in fact. They contain the fixes for
     a few issues we reported to the Rust project.

     In addition, a few cleanups indicated by the upgraded compiler or
     possible thanks to it. For instance, the compiler now detects
     redundant explicit links.

   - A couple changes to the Rust 'Makefile' so that it can be used with
     toybox tools, allowing Rust to be used in the Android kernel build.

Pull execve updates from Kees Cook:

 - Support non-BSS ELF segments with zero filesz

   Eric Biederman and I refactored ELF segment loading to handle the
   case where a segment has a smaller filesz than memsz. Traditionally
   linkers only did this for .bss and it was always the last segment. As
   a result, the kernel only handled this case when it was the last
   segment. We've had two recent cases where linkers were trying to use
   these kinds of segments for other reasons, and the were in the middle
   of the segment list. There was no good reason for the kernel not to
   support this, and the refactor actually ends up making things more
   readable too.

 - Enable namespaced binfmt_misc

   Christian Brauner has made it possible to use binfmt_misc with mount
   namespaces. This means some traditionally root-only interfaces (for
   adding/removing formats) are now more exposed (but believed to be
   safe).

 - Remove struct tag 'dynamic' from ELF UAPI

   Alejandro Colomar noticed that the ELF UAPI has been polluting the
   struct namespace with an unused and overly generic tag named
   "dynamic" for no discernible reason for many many years. After
   double-checking various distro source repositories, it has been

Pull x86 core updates from Thomas Gleixner:

 - Limit the hardcoded topology quirk for Hygon CPUs to those which have
   a model ID less than 4.

   The newer models have the topology CPUID leaf 0xB correctly
   implemented and are not affected.

 - Make SMT control more robust against enumeration failures

   SMT control was added to allow controlling SMT at boottime or
   runtime. The primary purpose was to provide a simple mechanism to
   disable SMT in the light of speculation attack vectors.

   It turned out that the code is sensible to enumeration failures and
   worked only by chance for XEN/PV. XEN/PV has no real APIC enumeration
   which means the primary thread mask is not set up correctly. By
   chance a XEN/PV boot ends up with smp_num_siblings == 2, which makes
   the hotplug control stay at its default value "enabled". So the mask
   is never evaluated.

   The ongoing rework of the topology evaluation caused XEN/PV to end up
   with smp_num_siblings == 1, which sets the SMT control to "not
   supported" and the empty primary thread mask causes the hotplug core
   to deny the bringup of the APS.

   Make the decision logic more robust and take 'not supported' and 'not
   implemented' into account for the decision whether a CPU should be
   booted or not.

 - Fake primary thread mask for XEN/PV

   Pretend that all XEN/PV vCPUs are primary threads, which makes the
   usage of the primary thread mask valid on XEN/PV. That is consistent
   with because all of the topology information on XEN/PV is fake or
   even non-existent.

 - Encapsulate topology information in cpuinfo_x86

   Move the randomly scattered topology data into a separate data
   structure for readability and as a preparatory step for the topology
   evaluation overhaul.

 - Consolidate APIC ID data type to u32

   It's fixed width hardware data and not randomly u16, int, unsigned
   long or whatever developers decided to use.

 - Cure the abuse of cpuinfo for persisting logical IDs.

   Per CPU cpuinfo is used to persist the logical package and die IDs.
   That's really not the right place simply because cpuinfo is subject
   to be reinitialized when a CPU goes through an offline/online cycle.

   Use separate per CPU data for the persisting to enable the further
   topology management rework. It will be removed once the new topology
   management is in place.

 - Provide a debug interface for inspecting topology information

   Useful in general and extremly helpful for validating the topology
   management rework in terms of correctness or "bug" compatibility.

Pull x86 APIC updates from Thomas Gleixner:

 - Make the quirk for non-maskable MSI interrupts in the affinity setter
   functional again.

   It was broken by a MSI core code update, which restructured the code
   in a way that the quirk flag was not longer set correctly.

   Trying to restore the core logic caused a deeper inspection and it
   turned out that the extra quirk flag is not required at all because
   it's the inverse of the reservation mode bit, which only can be set
   when the MSI interrupt is maskable.

   So the trivial fix is to use the reservation mode check in the
   affinity setter function and remove almost 40 lines of code related
   to the no-mask quirk flag.

 - Cure a Kconfig dependency issue which causes compile failures by
   correcting the conditionals in the affected header files.

 - Clean up coding style in the UV APIC driver.

Pull timer updates from Thomas Gleixner:
 "Updates for time, timekeeping and timers:

  Core:

   - Avoid superfluous deactivation of the tick in the low resolution
     tick NOHZ interrupt handler as the deactivation is handled already
     in the idle loop and on interrupt exit.

   - Update stale comments in the tick NOHZ code and rename the tick
     handler functions to be self-explanatory.

   - Remove an unused function in the tick NOHZ code, which was
     forgotten when the last user went away.

   - Handle RTC alarms which exceed the maximum alarm time of the
     underlying RTC hardware gracefully.

     Setting RTC alarms which exceed the maximum alarm time of the RTC
     hardware failed so far and caused suspend operations to abort.

     Cure this by limiting the alarm to the maximum alarm time of the
     RTC hardware, which is provided by the driver. This causes early
     resume wakeups, but that's way better than not suspending at all.

  Drivers:

   - Add a proper clocksource/event driver for the ancient Cirrus Logic
     EP93xx SoC family, which is one of the last non device-tree
     holdouts in arch/arm.

   - The usual boring device tree bindings updates and small fixes and

Pull SMP and CPU hotplug updates from Thomas Gleixner:

 - Switch the smp_call_function*() @csd argument to call_single_data_t
   type, which is a cache-line aligned typedef of the underlying struct
   __call_single_data.

   This ensures that the call data is not crossing a cacheline which
   avoids bouncing an extra cache-line for the SMP function call

 - Prevent offlining of the last housekeeping CPU when CPU isolation is
   active.

   Offlining the last housekeeping CPU makes no sense in general, but
   also caused the scheduler to panic due to the empty CPU mask when
   rebuilding the scheduler domains.

Pull irq updates from Thomas Gleixner:
 "Core:

   - Exclude managed interrupts in the calculation of interrupts which
     are targeted to a CPU which is about to be offlined to ensure that
     there are enough free vectors on the still online CPUs to migrate
     them over.

     Managed interrupts do not need to be accounted because they are
     either shut down on offline or migrated to an already reserved and
     guaranteed slot on a still online CPU in the interrupts affinity
     mask.

     Including managed interrupts is overaccounting and can result in
     needlessly aborting hibernation on large server machines.

Pull core updates from Thomas Gleixner:
 "Two small updates to ptrace_stop():

   - Add a comment to explain that the preempt_disable() before
     unlocking tasklist lock is not a correctness problem and just
     avoids the tracer to preempt the tracee before the tracee schedules
     out.

   - Make that preempt_disable() conditional on PREEMPT_RT=n.

     RT enabled kernels cannot disable preemption at this point because
     cgroup_enter_frozen() and sched_submit_work() acquire spinlocks or
     rwlocks which are substituted by sleeping locks on RT. Acquiring a
     sleeping lock in a preemption disable region is obviously not
     possible.
