      Pull io_uring futex support from Jens Axboe:
       "This adds support for using futexes through io_uring - first futex
        wake and wait, and then the vectored variant of waiting, futex waitv.
      
        For both wait/wake/waitv, we support the bitset variant, as the
        'normal' variants can be easily implemented on top of that.
      
        PI and requeue are not supported through io_uring, just the above
        mentioned parts. This may change in the future, but in the spirit of
        keeping this small (and based on what people have been asking for),
        this is what we currently have.
      
        Wake support is pretty straight forward, most of the thought has gone
        into the wait side to avoid needing to offload wait operations to a
        blocking context. Instead, we rely on the usual callbacks to retry and
        post a completion event, when appropriate.
      
        As far as I can recall, the first request for futex support with
        io_uring came from Andres Freund, working on postgres. His aio rework
        of postgres was one of the early adopters of io_uring, and futex
        support was a natural extension for that. This is relevant from both a
        usability point of view, as well as for effiency and performance. In
        Andres's words, for the former:
      
           Futex wait support in io_uring makes it a lot easier to avoid
           deadlocks in concurrent programs that have their own buffer pool:
           Obviously pages in the application buffer pool have to be locked
           during IO. If the initiator of IO A needs to wait for a held lock
           B, the holder of lock B might wait for the IO A to complete. The
           ability to wait for a lock and IO completions at the same time
           provides an efficient way to avoid such deadlocks
      
        and in terms of effiency, even without unlocking the full potential
        yet, Andres says:
      
           Futex wake support in io_uring is useful because it allows for more
           efficient directed wakeups. For some "locks" postgres has queues
           implemented in userspace, with wakeup logic that cannot easily be
           implemented with FUTEX_WAKE_BITSET on a single "futex word"
           (imagine waiting for journal flushes to have completed up to a
           certain point).
      
           Thus a "lock release" sometimes need to wake up many processes in a
           row. A quick-and-dirty conversion to doing these wakeups via
           io_uring lead to a 3% throughput increase, with 12% fewer context
           switches, albeit in a fairly extreme workload"

       "This adds support for using getsockopt and setsockopt via io_uring.
      
        The main use cases for this is to enable use of direct descriptors,
        rather than first instantiating a normal file descriptor, doing the
        option tweaking needed, then turning it into a direct descriptor. With
        this support, we can avoid needing a regular file descriptor

      Pull x86 TDX updates from Dave Hansen:
       "The majority of this is a rework of the assembly and C wrappers that
        are used to talk to the TDX module and VMM. This is a nice cleanup in
        general but is also clearing the way for using this code when Linux is
        the TDX VMM.
      
        There are also some tidbits to make TDX guests play nicer with Hyper-V
        and to take advantage the hardware TSC.
      
        Summary:
      
         - Refactor and clean up TDX hypercall/module call infrastructure
      
         - Handle retrying/resuming page conversion hypercalls

       "No major architecture features this time around, just some new HWCAP
        definitions, support for the Ampere SoC PMUs and a few fixes/cleanups.
      
        The bulk of the changes is reworking of the CPU capability checking
        code (cpus_have_cap() etc).
      
         - Major refactoring of the CPU capability detection logic resulting
           in the removal of the cpus_have_const_cap() function and migrating
           the code to "alternative" branches where possible

         - Perf and PMU:
      
            - Add support for Ampere SoC PMUs
      
            - Multi-DTC improvements for larger CMN configurations with
              multiple Debug & Trace Controllers
      
            - Rework the Arm CoreSight PMU driver to allow separate
              registration of vendor backend modules
      
            - Fixes: add missing MODULE_DEVICE_TABLE to the amlogic perf
              driver; use device_get_match_data() in the xgene driver; fix
              NULL pointer dereference in the hisi driver caused by calling
              cpuhp_state_remove_instance(); use-after-free in the hisi driver
      
         - HWCAP updates:
      
            - FEAT_SVE_B16B16 (BFloat16)
      
            - FEAT_LRCPC3 (release consistency model)
      
            - FEAT_LSE128 (128-bit atomic instructions)
      
         - SVE: remove a couple of pseudo registers from the cpufeature code.
           There is logic in place already to detect mismatched SVE features
      
         - Miscellaneous:
      
            - Reduce the default swiotlb size (currently 64MB) if no ZONE_DMA
              bouncing is needed. The buffer is still required for small
              kmalloc() buffers
      
            - Fix module PLT counting with !RANDOMIZE_BASE
      
            - Restrict CPU_BIG_ENDIAN to LLVM IAS 15.x or newer move
              synchronisation code out of the set_ptes() loop

      Pull clk driver updates from Stephen Boyd:
       "Herein lies a smallish collection of clk driver updates and some core
        clk framework changes for the merge window. The core framework changes
        are only improving the debugfs interface to allow phase adjustments
        and report which consumers of a clk there are. These are most likely
        only of interest to kernel developers.
      
        On the clk driver side, it's a ghastly amount of updates with only a
        handful of new clk drivers. We have a couple new clk drivers for
        Qualcomm, per usual, and a driver for Renesas, Amlogic, and TI
        respectively. The updates are spread throughout the clk drivers.
      
        Some highlights are fixing kunit tests for different configurations
        like lockdep and big-endian, avoiding integer overflow in rate
        settable clks, moving clk_hw_onecell_data to the end of allocations so
        that drivers don't corrupt their private data, and migrating clk
        drivers to the regmap maple tree. Otherwise it's the usual fixes to
        clk drivers that only come along with testing the drivers on real
        hardware.
      
        New Drivers:
         - Add clock driver for TWL6032
         - Initial support for the Qualcomm SM4450 Global Clock Controller and
           SM4450 RPMh clock controllers
         - Add Camera Clock Controller on Qualcomm SM8550
         - Add support for the Renesas RZ/G3S (R9A08G045) SoC
         - Add Amlogic s4 main clock controller support
      
      Updates:
         - Make clk kunit tests work with lockdep
         - Fix clk gate kunit test for big-endian
         - Convert more than a handful of clk drivers to use regmap maple tree
         - Consider the CLK_FRAC_DIVIDER_ZERO_BASED in fractional divider clk
           implementation
         - Add consumer info to clk debugfs
         - Fix various clk drivers that have clk_hw_onecell_data not at the
           end of an allocation
         - Drop CLK_SET_RATE_PARENT for clocks with fixed-rate GPLLs across a
           variety of Qualcomm IPQ platforms
         - Add missing parent of APCS PLL on Qualcomm IPQ6018
         - Add I2C QUP6 clk on Qualcomm IPQ6018 but mark it critical to avoid
           problems with RPM
         - Implement safe source switching for a53pll and use on Qualcomm
           IPQ5332
         - Add support for Stromer Plus PLLs to Qualcomm clk driver
         - Switch Qualcomm SM8550 Video and GPU clock controllers to use OLE
           PLL configure method
         - Non critical fixes to halt bit checks in Qualcomm clk drivers
         - Add SMMU GDSC for Qualcomm MSM8998
         - Fix possible integer overflow in Qualcomm RCG frequency calculation
           code
         - Remove RPM managed clks from Qualcomm MSM8996 GCC driver
         - Add HFPLL configuration for the three HFPLLs in Qualcomm MSM8976
         - Switch Qualcomm MSM8996 CBF clock driver's remove function to
           return void
         - Fix missing dependency for s4 clock controllers
         - Select MXC_CLK when building in the CLK_IMX8QXP
         - Fixes for error handling paths in i.MX8 ACM driver
         - Move the clocks check in i.MX8 ACM driver in order to log any error
         - Drop the unused return value of clk_imx_acm_detach_pm_domains
         - Drop non-existant IMX8MP_CLK_AUDIOMIX_PDM_ROOT clock
         - Fix error handling in i.MX8MQ clock driver
         - Allow a different LCDIF1 clock parent if DT describes it for
           i.MX6SX
         - Keep the SCU resource table sorted in the i.MX8DXL rsrc driver
         - Move the elcdif PLL clock registration above lcd_clk, as it is its
           parent
         - Correct some ENET specific clocks for i.MX8DXL platform
         - Drop the VPU_UART and VPUCORE from i.MX8QM as latest HW revision
           doesn't have them
         - Remove "de-featured" MLB support from i.MX8QM/QXP/DXL platforms
         - Skip registering clocks owned by Cortex-A partition SCU-based
           platforms
         - Add CAN_1/2 to i.MX8QM and M4_0, PI_0_PWM_0 and PI_0_I2C_0 to
           i.MX8QXP resources"

      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

      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:
      
         - Add symbol definitions related to CDAT to the ACPICA code (Dave
           Jiang)

           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)

         - Fix AER info corruption in aer_recover_queue() when error status
           data has multiple sections (Shiju Jose)
      
         - Make APEI use ERST maximum execution time for slow devices (Jeshua
           Smith)

           subspaces (Huisong Li)
      
         - Define common macros to use when referring to various bitfields in
           the PCC generic communications channel command and status fields

           places (Raag Jadav)
      
         - Use acpi_device_uid() for fetching _UID in 2 places (Raag Jadav)
      
         - Add context argument to acpi_dev_install_notify_handler() (Rafael
           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.
      
         - A lot of __counted_by() annotations, from Kees.
      
         - A lot of strncpy -> strscpy and printf format fixes.
      
         - Replace master/slave terminology with conduit/user in DSA drivers.
      
         - Handful of KUnit tests for netdev and WiFi core.
      
        Removed:
      
         - AppleTalk COPS.
      
         - AppleTalk ipddp.
      
         - TI AR7 CPMAC Ethernet driver.
      
        Drivers:
      
         - Ethernet high-speed NICs:
            - Intel (100G, ice, idpf):
               - add a driver for the Intel E2000 IPUs
               - make CRC/FCS stripping configurable
               - cross-timestamping for E823 devices
               - basic support for E830 devices
               - use aux-bus for managing client drivers
               - i40e: report firmware versions via devlink

         - Upgrade to Rust 1.73.0
      
           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.

       - 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.

       - SLUB: slab order calculation refactoring (Vlastimil Babka, Feng Tang)
      
         Recent proposals to tune the slab order calculations have prompted us
         to look at the current code and refactor it to make it easier to
         follow and eliminate some odd corner cases.
      
         The refactoring is mostly non-functional changes, but should make the
         actual tuning easier to implement and review.

      Pull RCU updates from Frederic Weisbecker:
      
       - RCU torture, locktorture and generic torture infrastructure updates
         that include various fixes, cleanups and consolidations.
      
         Among the user visible things, ftrace dumps can now be found into
         their own file, and module parameters get better documented and
         reported on dumps.
      
       - Generic and misc fixes all over the place. Some highlights:
      
           * Hotplug handling has seen some light cleanups and comments
      
           * An RCU barrier can now be triggered through sysfs to serialize
             memory stress testing and avoid OOM
      
           * Object information is now dumped in case of invalid callback
             invocation
      
           * Also various SRCU issues, too hard to trigger to deserve urgent
             pull requests, have been fixed
      
       - RCU documentation updates
      
       - RCU reference scalability test minor fixes and doc improvements.
      
       - RCU tasks minor fixes
      
       - Stall detection updates. Introduce RCU CPU Stall notifiers that
         allows a subsystem to provide informations to help debugging. Also
         cure some false positive stalls.

        This is useful in deployments in which a clean panic is preferable to
