      Pull thermal control updates from Rafael Wysocki:
       "These mostly continue to prepare the thermal control subsystem for
        using unified representation of trip points, which includes cleanups,
        code refactoring and similar and update several drivers (for other
        reasons), which includes new hardware support.
      
        Specifics:
      
         - Add a thermal zone 'devdata' accessor and modify several drivers to
           use it (Daniel Lezcano)
      
         - Prevent drivers from using the 'device' internal thermal zone
           structure field directly (Daniel Lezcano)
      
         - Clean up the hwmon thermal driver (Daniel Lezcano)

         - Add more thermal zone device encapsulation: prevent setting
           structure field directly, access the sensor device instead the
           thermal zone's device for trace, relocate the traces in
           drivers/thermal (Daniel Lezcano)
      
         - Use the generic trip point for the i.MX and remove the
           get_trip_temp ops (Daniel Lezcano)

           (Yang Li)
      
         - Remove R-Car H3 ES1.* handling as public has only access to the ES2
           version and the upstream support for the ES1 has been shutdown
           (Wolfram Sang)
      
         - Add a delay after initializing the bank in order to let the time to
           the hardware to initialze itself before reading the temperature
           (Amjad Ouled-Ameur)

           driver (Ye Xingchen)
      
         - Detect power gated thermal zones and return -EAGAIN when reading
           the temperature (Mikko Perttunen)
      
         - Remove thermal_bind_params structure as it is unused (Zhang Rui)
      
         - Drop unneeded quotes in DT bindings allowing to run yamllint (Rob
           Herring)
      
         - Update the power allocator documentation according to the thermal
           trace relocation (Lukas Bulwahn)

         - Use the dev_err_probe() helper in the Amlogic driver (Ye Xingchen)
      
         - Add AP domain support to LVTS thermal controllers for mt8195
           (Balsam CHIHI)
      
         - Remove buggy call to thermal_of_zone_unregister() (Daniel Lezcano)
      
         - Make thermal_of_zone_[un]register() private to the thermal OF code
           (Daniel Lezcano)
      
         - Create a private copy of the thermal zone device parameters
           structure when registering a thermal zone (Daniel Lezcano)

      Pull remoteproc updates from Bjorn Andersson:
      
       - Unnecessary type casts from the 'void *' rproc->priv pointer are
         dropped throughout the 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

      Pull gpio updates from Bartosz Golaszewski:
       "We have some new drivers, significant refactoring of existing intel
        platforms, lots of improvements all around, mass conversion to using
        immutable irqchips by drivers that had not been converted individually
        yet and some changes in the core library code.
      
        Summary:
      
        New drivers:
         - add a driver for the Loongson GPIO controller
         - add a driver for the fxl6408 I2C GPIO expander
         - add a GPIO module containing code common for Intel Elkhart Lake and
           Merrifield platforms
         - add a driver for the Intel Elkhart Lake platform reusing the code
           from the intel tangier library
      
        GPIOLIB core:
         - GPIO ACPI improvements
         - simplify gpiochip_add_data_with_keys() fwnode handling
         - cleanup header inclusions (remove unneeded ones, order the rest
           alphabetically)
         - remove duplicate code (reuse krealloc() instead of open-coding it,
           drop a duplicated check in gpiod_find_and_request())
         - reshuffle the code to remove unnecessary forward declarations
         - coding style cleanups and improvements
         - add a helper for accessing device fwnodes
         - small updates in docs
      
        Driver improvements:
         - convert all remaining GPIO irqchip drivers to using immutable
           irqchips
         - drop unnecessary of_match_ptr() macro expansions
         - shrink the code in gpio-merrifield significantly by reusing the
           code from gpio-tangier + minor tweaks to the driver code
         - remove MODULE_LICENSE() from drivers that can only be built-in
         - add device-tree support to gpio-loongson1
         - use new regmap features in gpio-104-dio-48e and gpio-pcie-idio-24
         - minor tweaks and fixes to gpio-xra1403, gpio-sim, gpio-tegra194,
           gpio-omap, gpio-aspeed, gpio-raspberrypi-exp
         - shrink code in gpio-ich and gpio-pxa
         - Kconfig tweak for gpio-pmic-eic-sprd"

      Pull regulator updates from Mark Brown:
       "A fairly quiet release, there were some cleanup and a couple of new
        devices but the biggest change was converting most of the drivers to
        use asynchronous probe. This allows us to ramp up multiple regulators
        in parallel during boot which can have a noticable impact on modern
        systems.
      
        Summary:
      
         - Update of drivers to PROBE_PREFER_ASYNCHRONOUS to mitigate issues
           with ramp times slowing down boots.
      
         - Convert to void remove callbacks.

      Linus Torvalds authored
      Pull regmap updates from Mark Brown:
       "This is a much bigger change for regmap than is normal, the main
        things being the addition of some KUnit coverage and a maple tree
        based register cache which longer term is likely to replace the rbtree
        cache except possibly for very small register maps.
      
        While it's complete overkill for most applications the code for maple
        trees is there and there are some larger, sparser devices where the
        data structure is a better fit.
      
        The maple tree support is still a work in progress but already useful,
        there's some conversions of drivers ready to go after the merge
        window.
      
        Summary:
      
         - Support for shifting register addresses up as well as down, there's
           a use cases with memory mapped MDIO.
      
         - Refactoring of the type configuration in regmap-irq to allow access
           to driver data in the handler, needed by some GPIO devices.
      
         - Some initial KUnit coverage, the bulk of the driver facing API is
           covered but there's holes and things like the data marshalling for
           bytestream buses are just not covered in the slightest.
      
         - Removal of the compressed cache type, it had zero users and was
           getting in the way of KUnit.
      
         - Addition of a maple tree based register cache, there's more work to
           do but it's already useful for some devices with a flatter data
           structure than rbtree and getting to use all the optimisation work
           Liam is doing"

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

      Pull arm64 updates from Will Deacon:
       "ACPI:
      
         - Improve error reporting when failing to manage SDEI on AGDI device
           removal
      
        Assembly routines:
      
         - Improve register constraints so that the compiler can make use of
           the zero register instead of moving an immediate #0 into a GPR
      
         - Allow the compiler to allocate the registers used for CAS
           instructions
      
        CPU features and system registers:
      
         - Cleanups to the way in which CPU features are identified from the
           ID register fields
      
         - Extend system register definition generation to handle Enum types
           when defining shared register fields
      
         - Generate definitions for new _EL2 registers and add new fields for
           ID_AA64PFR1_EL1
      
         - Allow SVE to be disabled separately from SME on the kernel
           command-line
      
        Tracing:
      
         - Support for "direct calls" in ftrace, which enables BPF tracing for
           arm64
      
        Kdump:
      
         - Don't bother unmapping the crashkernel from the linear mapping,
           which then allows us to use huge (block) mappings and reduce TLB
           pressure when a crashkernel is loaded.
      
        Memory management:
      
         - Try again to remove data cache invalidation from the coherent DMA
           allocation path
      
         - Simplify the fixmap code by mapping at page granularity
      
         - Allow the kfence pool to be allocated early, preventing the rest of
           the linear mapping from being forced to page granularity
      
        Perf and PMU:
      
         - Move CPU PMU code out to drivers/perf/ where it can be reused by
           the 32-bit ARM architecture when running on ARMv8 CPUs
      
         - Fix race between CPU PMU probing and pKVM host de-privilege
      
         - Add support for Apple M2 CPU PMU
      
         - Adjust the generic PERF_COUNT_HW_BRANCH_INSTRUCTIONS event
           dynamically, depending on what the CPU actually supports
      
         - Minor fixes and cleanups to system PMU drivers
      
        Stack tracing:
      
         - Use the XPACLRI instruction to strip PAC from pointers, rather than
           rolling our own function in C
      
         - Remove redundant PAC removal for toolchains that handle this in
           their builtins
      
         - Make backtracing more resilient in the face of instrumentation
      
        Miscellaneous:
      
         - Fix single-step with KGDB
      
         - Remove harmless warning when 'nokaslr' is passed on the kernel
           command-line

        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

           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 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 was 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"

      Pull x86 APIC updates from Thomas Gleixner:
      
       - Fix the incorrect handling of atomic offset updates in
         reserve_eilvt_offset()
      
         The check for the return value of atomic_cmpxchg() is not compared
         against the old value, it is compared against the new value, which
         makes it two round on success.
      
         Convert it to atomic_try_cmpxchg() which does the right thing.
      
       - Handle IO/APIC less systems correctly
      
         When IO/APIC is not advertised by ACPI then the computation of the
         lower bound for dynamically allocated interrupts like MSI goes wrong.
      
         This lower bound is used to exclude the IO/APIC legacy GSI space as
         that must stay reserved for the legacy interrupts.
      
         In case that the system, e.g. VM, does not advertise an IO/APIC the
         lower bound stays at 0.
      
         0 is an invalid interrupt number except for the legacy timer
         interrupt on x86. The return value is unchecked in the core code, so
         it ends up to allocate interrupt number 0 which is subsequently
         considered to be invalid by the caller, e.g. the MSI allocation code.
      
         A similar problem was already cured for device tree based systems
         years ago, but that missed - or did not envision - the zero IO/APIC
         case.
      
         Consolidate the zero check and return the provided "from" argument to
         the core code call site, which is guaranteed to be greater than 0.
      
       - Simplify the X2APIC cluster CPU mask logic for CPU hotplug
      
         Per cluster CPU masks are required for X2APIC in cluster mode to
         determine the correct cluster for a target CPU when calculating the
         destination for IPIs
      
         These masks are established when CPUs are borught up. The first CPU
         in a cluster must allocate a new cluster CPU mask. As this happens
         during the early startup of a CPU, where memory allocations cannot be
         done, the mask has to be allocated by the control CPU.
      
         The current implementation allocates a clustermask just in case and
         if the to be brought up CPU is the first in a cluster the CPU takes
         over this allocation from a global pointer.
      
         This works nicely in the fully serialized CPU bringup scenario which
         is used today, but would fail completely for parallel bringup of
         CPUs.
      
         The cluster association of a CPU can be computed from the APIC ID
         which is enumerated by ACPI/MADT.
      
         So the cluster CPU masks can be preallocated and associated upfront
         and the upcoming CPUs just need to set their corresponding bit.
      
         Aside of preparing for parallel bringup this is a valuable
         simplification on its own.
      
       - Remove global variables which control the early startup of secondary
         CPUs on 64-bit
      
         The only information which is needed by a starting CPU is the Linux
         CPU number. The CPU number allows it to retrieve the rest of the
         required data from already existing per CPU storage.
      
         So instead of initial_stack, early_gdt_desciptor and initial_gs
         provide a new variable smpboot_control which contains the Linux CPU
         number for now. The starting CPU can retrieve and compute all
         required information for startup from there.
      
         Aside of being a cleanup, this is also preparing for parallel CPU
         bringup, where starting CPUs will look up their Linux CPU number via
         the APIC ID, when smpboot_control has the corresponding control bit
         set.
      
       - Make cc_vendor globally accesible
      
         Subsequent parallel bringup changes require access to cc_vendor
         because confidental computing platforms need special treatment in the
         early startup phase vs. CPUID and APCI ID readouts.
      
         The change makes cc_vendor global and provides stub accessors in case
         that CONFIG_ARCH_HAS_CC_PLATFORM is not set.
      
         This was merged from the x86/cc branch in anticipation of further
         parallel bringup commits which require access to cc_vendor. Due to
         late discoveries of fundamental issue with those patches these
         commits never happened.
      
         The merge commit is unfortunately in the middle of the APIC commits
         so unraveling it would have required a rebase or revert. As the
         parallel bringup seems to be well on its way for 6.5 this would be
         just pointless churn. As the commit does not contain any functional
         change it's not a risk to keep it.

      Pull timers and timekeeping updates from Thomas Gleixner:
      
       - Improve the VDSO build time checks to cover all dynamic relocations
      
         VDSO does not allow dynamic relocations, but the build time check is
         incomplete and fragile.
      
         It's based on architectures specifying the relocation types to search
         for and does not handle R_*_NONE relocation entries correctly.
         R_*_NONE relocations are injected by some GNU ld variants if they
         fail to determine the exact .rel[a]/dyn_size to cover trailing zeros.
         R_*_NONE relocations must be ignored by dynamic loaders, so they
         should be ignored in the build time check too.
      
         Remove the architecture specific relocation types to check for and
         validate strictly that no other relocations than R_*_NONE end up in
         the VSDO .so file.
      
       - Prefer signal delivery to the current thread for
         CLOCK_PROCESS_CPUTIME_ID based posix-timers
      
         Such timers prefer to deliver the signal to the main thread of a
         process even if the context in which the timer expires is the current
         task. This has the downside that it might wake up an idle thread.
      
         As there is no requirement or guarantee that the signal has to be
         delivered to the main thread, avoid this by preferring the current
         task if it is part of the thread group which shares sighand.
      
         This not only avoids waking idle threads, it also distributes the
         signal delivery in case of multiple timers firing in the context of
         different threads close to each other better.
      
       - Align the tick period properly (again)
      
         For a long time the tick was starting at CLOCK_MONOTONIC zero, which
         allowed users space applications to either align with the tick or to
         place a periodic computation so that it does not interfere with the
         tick. The alignement of the tick period was more by chance than by
         intention as the tick is set up before a high resolution clocksource
         is installed, i.e. timekeeping is still tick based and the tick
         period advances from there.
      
         The early enablement of sched_clock() broke this alignement as the
         time accumulated by sched_clock() is taken into account when
         timekeeping is initialized. So the base value now(CLOCK_MONOTONIC) is
         not longer a multiple of tick periods, which breaks applications
         which relied on that behaviour.
      
         Cure this by aligning the tick starting point to the next multiple of
         tick periods, i.e 1000ms/CONFIG_HZ.
      
       - A set of NOHZ fixes and enhancements:
      
           * Cure the concurrent writer race for idle and IO sleeptime
             statistics
      
             The statitic values which are exposed via /proc/stat are updated
             from the CPU local idle exit and remotely by cpufreq, but that
             happens without any form of serialization. As a consequence
             sleeptimes can be accounted twice or worse.
      
             Prevent this by restricting the accumulation writeback to the CPU
             local idle exit and let the remote access compute the accumulated
             value.
      
           * Protect idle/iowait sleep time with a sequence count
      
             Reading idle/iowait sleep time, e.g. from /proc/stat, can race
             with idle exit updates. As a consequence the readout may result
             in random and potentially going backwards values.
      
             Protect this by a sequence count, which fixes the idle time
             statistics issue, but cannot fix the iowait time problem because
             iowait time accounting races with remote wake ups decrementing
             the remote runqueues nr_iowait counter. The latter is impossible
             to fix, so the only way to deal with that is to document it
             properly and to remove the assertion in the selftest which
             triggers occasionally due to that.
      
           * Restructure struct tick_sched for better cache layout
      
           * Some small cleanups and a better cache layout for struct
             tick_sched
      
       - Implement the missing timer_wait_running() callback for POSIX CPU
         timers
      
         For unknown reason the introduction of the timer_wait_running()
         callback missed to fixup posix CPU timers, which went unnoticed for
         almost four years.
      
         While initially only targeted to prevent livelocks between a timer
         deletion and the timer expiry function on PREEMPT_RT enabled kernels,
         it turned out that fixing this for mainline is not as trivial as just
         implementing a stub similar to the hrtimer/timer callbacks.
      
         The reason is that for CONFIG_POSIX_CPU_TIMERS_TASK_WORK enabled
         systems there is a livelock issue independent of RT.
      
         CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y moves the expiry of POSIX CPU
         timers out from hard interrupt context to task work, which is handled
         before returning to user space or to a VM. The expiry mechanism moves
         the expired timers to a stack local list head with sighand lock held.
         Once sighand is dropped the task can be preempted and a task which
         wants to delete a timer will spin-wait until the expiry task is
         scheduled back in. In the worst case this will end up in a livelock
         when the preempting task and the expiry task are pinned on the same
         CPU.
      
         The timer wheel has a timer_wait_running() mechanism for RT, which
         uses a per CPU timer-base expiry lock which is held by the expiry
         code and the task waiting for the timer function to complete blocks
         on that lock.
      
         This does not work in the same way for posix CPU timers as there is
         no timer base and expiry for process wide timers can run on any task
         belonging to that process, but the concept of waiting on an expiry
         lock can be used too in a slightly different way.
      
         Add a per task mutex to struct posix_cputimers_work, let the expiry
         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

      Pull core debugobjects update from Thomas Gleixner:
       "A single update to debugobjects:
      
        Prevent a race vs statically initialized objects. Such objects are
        usually not initialized via an init() function. They are special cased
        and detected on first use under the assumption that they are already
        correctly initialized via the static initializer.
      
        This works correctly unless there are two concurrent debug object
        operations on such an object.
      
        The first one detects that the object is not yet tracked and tries to
        establish a tracking object after dropping the debug objects hash
        bucket lock. The concurrent operation does the same. The one which
        wins the race ends up modifying the state of the object which makes
        the other one fail resulting in a bogus debug objects warning.
      
        Prevent this by making the detection of a static object and the
        allocation of a tracking object atomic under the hash bucket lock. So
        the first one to acquire the hash bucket lock will succeed and the
        second one will observe the correct tracking state.
      
        This race existed forever but was only exposed when the timer wheel
        code added a debug_object_assert_init() call outside of the timer base

       - Add the necessary glue so that the kernel can run as a confidential
         SEV-SNP vTOM guest on Hyper-V. A vTOM guest basically splits the
         address space in two parts: encrypted and unencrypted. The use case
         being running unmodified guests on the Hyper-V confidential computing
         hypervisor
      
       - Double-buffer messages between the guest and the hardware PSP device
         so that no partial buffers are copied back'n'forth and thus potential
         message integrity and leak attacks are possible
      
       - Name the return value the sev-guest driver returns when the hw PSP
         device hasn't been called, explicitly
      
       - Cleanups

      media: ov5670: Fix probe on ACPI · 73b41dc5
      Sakari Ailus authored
      devm_clk_get() will return either an error or NULL, which the driver
      handles, continuing to use the clock of reading the value of the
      clock-frequency property.
      
      However, the value of ov5670->xvclk is left as-is and the other clock
      framework functions aren't capable of handling error values.
      
      Use devm_clk_get_optional() to obtain NULL instead of -ENOENT.
