      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 ACPI updates from Rafael Wysocki:
       "These fix issues, add new quirks, rearrange the IRQ override quirk
        definitions, add new helpers and switch over code to using them,
        rework a couple of interfaces to be more flexible, eliminate strncpy()
        usage from PNP, extend the ACPI PCC mailbox driver and clean up code.
      
        This is based on ACPI thermal driver changes that are present in the
        thermal control updates for 6.7-rc1 pull request (they are depended on
        by the ACPI utilities updates). However, the ACPI thermal driver
        changes are not included in the list of specific ACPI changes below.
      
        Specifics:

           acpi_scan_device_not_present() to be about enumeration (James
           Morse)
      
         - Add __printf format attribute to acpi_os_vprintf() (Su Hui)

           for fpdt_process_subtable() to acpi_init_fpdt() (Vasily Khoruzhick)
      
         - Rework acpi_handle_list handling so as to manage it dynamically,
           including size computation (Rafael Wysocki)
      
         - Clean up ACPI utilities code so as to make it follow the kernel
           coding style (Jonathan Bergh)
      
         - Consolidate IRQ trigger-type override DMI tables and drop .ident
           values from dmi_system_id tables used for ACPI resources management
           quirks (Hans de Goede)

           places (Raag Jadav)
      
         - Use acpi_device_uid() for fetching _UID in 2 places (Raag Jadav)

           Wysocki)
      
         - Clarify ACPI bus concepts in the ACPI device enumeration
           documentation (Rafael Wysocki)
      
         - Switch over the ACPI AC and ACPI PAD drivers to using the platform
           driver interface which, is more logically consistent than binding a
           driver directly to an ACPI device object, and clean them up (Michal
           Wilczynski)
      
         - Replace strncpy() in the PNP code with either memcpy() or strscpy()
           as appropriate (Justin Stitt)

      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.
      
         - Add open-coded task, css_task and css iterator support. One of the
           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.
      
         - Add missed stats for kprobes to retrieve the number of missed
           kprobe executions and subsequent executions of BPF programs.
      
         - Inherit system settings for CPU security mitigations.
      
         - Add BPF v4 CPU instruction support for arm32 and s390x.
      
        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.
      
        Misc:
      
         - A lot of KCSAN data race "fixes", from Eric.

         - Upgrade to Rust 1.73.0

           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.

       - 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
         removed.

         follow and eliminate some odd corner cases.

      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.

       - 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.

       "Updates for time, timekeeping and timers:
      
        Core:
      
         - Avoid superfluous deactivation of the tick in the low resolution

           in the idle loop and on interrupt exit.

           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.

           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.
      
         - The usual set of small improvements
      
        Drivers:
      
         - Make the generic interrupt chip implementation handle interrupt
           domains correctly and initialize the name pointers correctly
      
         - Add interrupt affinity setting support to the Renesas RZG2L chip
           driver.
      
         - Prevent registering syscore operations multiple times in the SiFive
           PLIC chip driver.
      
         - Update device tree handling in the NXP Layerscape MSI chip driver"

       "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.
      
           This obviously brings back the potential slowdown of ptrace() for
           RT enabled kernels, but that's a price to be paid for latency
           guarantees"
