      Pull timer updates from Thomas Gleixner:
       "Updates for timers, timekeeping and drivers:
      
        Core:
      
         - The timer_shutdown[_sync]() infrastructure:
      
           Tearing down timers can be tedious when there are circular
           dependencies to other things which need to be torn down. A prime
           example is timer and workqueue where the timer schedules work and
           the work arms the timer.
      
           What needs to prevented is that pending work which is drained via
           destroy_workqueue() does not rearm the previously shutdown timer.
           Nothing in that shutdown sequence relies on the timer being
           functional.
      
           The conclusion was that the semantics of timer_shutdown_sync()
           should be:
      	- timer is not enqueued
          	- timer callback is not running
          	- timer cannot be rearmed
      
           Preventing the rearming of shutdown timers is done by discarding
           rearm attempts silently.
      
           A warning for the case that a rearm attempt of a shutdown timer is
           detected would not be really helpful because it's entirely unclear
           how it should be acted upon. The only way to address such a case is
           to add 'if (in_shutdown)' conditionals all over the place. This is
           error prone and in most cases of teardown not required all.
      
         - The real fix for the bluetooth HCI teardown based on
           timer_shutdown_sync().
      
           A larger scale conversion to timer_shutdown_sync() is work in
           progress.
      
         - Consolidation of VDSO time namespace helper functions
      
         - Small fixes for timer and timerqueue
      
        Drivers:
      
         - Prevent integer overflow on the XGene-1 TVAL register which causes
           an never ending interrupt storm.
      
         - The usual set of new device tree bindings
      
         - Small fixes and improvements all over the place"

      Pull irq updates from Thomas Gleixner:
       "Updates for the interrupt core and driver subsystem:
      
        The bulk is the rework of the MSI subsystem to support per device MSI
        interrupt domains. This solves conceptual problems of the current
        PCI/MSI design which are in the way of providing support for
        PCI/MSI[-X] and the upcoming PCI/IMS mechanism on the same device.
      
        IMS (Interrupt Message Store] is a new specification which allows
        device manufactures to provide implementation defined storage for MSI
        messages (as opposed to PCI/MSI and PCI/MSI-X that has a specified
        message store which is uniform accross all devices). The PCI/MSI[-X]
        uniformity allowed us to get away with "global" PCI/MSI domains.
      
        IMS not only allows to overcome the size limitations of the MSI-X
        table, but also gives the device manufacturer the freedom to store the
        message in arbitrary places, even in host memory which is shared with
        the device.
      
        There have been several attempts to glue this into the current MSI
        code, but after lengthy discussions it turned out that there is a
        fundamental design problem in the current PCI/MSI-X implementation.
        This needs some historical background.
      
        When PCI/MSI[-X] support was added around 2003, interrupt management
        was completely different from what we have today in the actively
        developed architectures. Interrupt management was completely
        architecture specific and while there were attempts to create common
        infrastructure the commonalities were rudimentary and just providing
        shared data structures and interfaces so that drivers could be written
        in an architecture agnostic way.
      
        The initial PCI/MSI[-X] support obviously plugged into this model
        which resulted in some basic shared infrastructure in the PCI core
        code for setting up MSI descriptors, which are a pure software
        construct for holding data relevant for a particular MSI interrupt,
        but the actual association to Linux interrupts was completely
        architecture specific. This model is still supported today to keep
        museum architectures and notorious stragglers alive.
      
        In 2013 Intel tried to add support for hot-pluggable IO/APICs to the
        kernel, which was creating yet another architecture specific mechanism
        and resulted in an unholy mess on top of the existing horrors of x86
        interrupt handling. The x86 interrupt management code was already an
        incomprehensible maze of indirections between the CPU vector
        management, interrupt remapping and the actual IO/APIC and PCI/MSI[-X]
        implementation.
      
        At roughly the same time ARM struggled with the ever growing SoC
        specific extensions which were glued on top of the architected GIC
        interrupt controller.
      
        This resulted in a fundamental redesign of interrupt management and
        provided the today prevailing concept of hierarchical interrupt
        domains. This allowed to disentangle the interactions between x86
        vector domain and interrupt remapping and also allowed ARM to handle
        the zoo of SoC specific interrupt components in a sane way.
      
        The concept of hierarchical interrupt domains aims to encapsulate the
        functionality of particular IP blocks which are involved in interrupt
        delivery so that they become extensible and pluggable. The X86
        encapsulation looks like this:
      
                                                  |--- device 1
           [Vector]---[Remapping]---[PCI/MSI]--|...
                                                  |--- device N
      
        where the remapping domain is an optional component and in case that
        it is not available the PCI/MSI[-X] domains have the vector domain as
        their parent. This reduced the required interaction between the
        domains pretty much to the initialization phase where it is obviously
        required to establish the proper parent relation ship in the
        components of the hierarchy.
      
        While in most cases the model is strictly representing the chain of IP
        blocks and abstracting them so they can be plugged together to form a
        hierarchy, the design stopped short on PCI/MSI[-X]. Looking at the
        hardware it's clear that the actual PCI/MSI[-X] interrupt controller
        is not a global entity, but strict a per PCI device entity.
      
        Here we took a short cut on the hierarchical model and went for the
        easy solution of providing "global" PCI/MSI domains which was possible
        because the PCI/MSI[-X] handling is uniform across the devices. This
        also allowed to keep the existing PCI/MSI[-X] infrastructure mostly
        unchanged which in turn made it simple to keep the existing
        architecture specific management alive.
      
        A similar problem was created in the ARM world with support for IP
        block specific message storage. Instead of going all the way to stack
        a IP block specific domain on top of the generic MSI domain this ended
        in a construct which provides a "global" platform MSI domain which
        allows overriding the irq_write_msi_msg() callback per allocation.
      
        In course of the lengthy discussions we identified other abuse of the
        MSI infrastructure in wireless drivers, NTB etc. where support for
        implementation specific message storage was just mindlessly glued into
        the existing infrastructure. Some of this just works by chance on
        particular platforms but will fail in hard to diagnose ways when the
        driver is used on platforms where the underlying MSI interrupt
        management code does not expect the creative abuse.
      
        Another shortcoming of today's PCI/MSI-X support is the inability to
        allocate or free individual vectors after the initial enablement of
        MSI-X. This results in an works by chance implementation of VFIO (PCI
        pass-through) where interrupts on the host side are not set up upfront
        to avoid resource exhaustion. They are expanded at run-time when the
        guest actually tries to use them. The way how this is implemented is
        that the host disables MSI-X and then re-enables it with a larger
        number of vectors again. That works by chance because most device
        drivers set up all interrupts before the device actually will utilize
        them. But that's not universally true because some drivers allocate a
        large enough number of vectors but do not utilize them until it's
        actually required, e.g. for acceleration support. But at that point
        other interrupts of the device might be in active use and the MSI-X
        disable/enable dance can just result in losing interrupts and
        therefore hard to diagnose subtle problems.
      
        Last but not least the "global" PCI/MSI-X domain approach prevents to
        utilize PCI/MSI[-X] and PCI/IMS on the same device due to the fact
        that IMS is not longer providing a uniform storage and configuration
        model.
      
        The solution to this is to implement the missing step and switch from
        global PCI/MSI domains to per device PCI/MSI domains. The resulting
        hierarchy then looks like this:
      
                                    |--- [PCI/MSI] device 1
           [Vector]---[Remapping]---|...
                                    |--- [PCI/MSI] device N
      
        which in turn allows to provide support for multiple domains per
        device:
      
                                    |--- [PCI/MSI] device 1
                                    |--- [PCI/IMS] device 1
           [Vector]---[Remapping]---|...
                                    |--- [PCI/MSI] device N
                                    |--- [PCI/IMS] device N
      
        This work converts the MSI and PCI/MSI core and the x86 interrupt
        domains to the new model, provides new interfaces for post-enable
        allocation/free of MSI-X interrupts and the base framework for
        PCI/IMS. PCI/IMS has been verified with the work in progress IDXD
        driver.
      
        There is work in progress to convert ARM over which will replace the
        platform MSI train-wreck. The cleanup of VFIO, NTB and other creative
        "solutions" are in the works as well.

      Pull s390 updates from Alexander Gordeev:
      
       - Factor out handle_write() function and simplify 3215 console write
         operation
      
       - When 3170 terminal emulator is connected to the 3215 console driver
         the boot time could be very long due to limited buffer space or
         missing operator input. Add con3215_drop command line parameter and
         con3215_drop sysfs attribute file to instruct the kernel drop console
         data when such conditions are met
      
       - Fix white space errors in 3215 console driver
      
       - Move enum paiext_mode definition to a header file and rename it to
         paievt_mode to indicate this is now used for several events. Rename
         PAI_MODE_COUNTER to PAI_MODE_COUNTING to make consistent with
         PAI_MODE_SAMPLING
      
       - Simplify the logic of PMU pai_crypto mapped buffer reference counter
         and make it consistent with PMU pai_ext
      
       - Rename PMU pai_crypto mapped buffer structure member users to
         active_events to make it consistent with PMU pai_ext
      
       - Enable HUGETLB_PAGE_OPTIMIZE_VMEMMAP configuration option. This
         results in saving of 12K per 1M hugetlb page (~1.2%) and 32764K per
         2G hugetlb page (~1.6%)
      
       - Use generic serial.h, bugs.h, shmparam.h and vga.h header files and
         scrap s390-specific versions
      
       - The generic percpu setup code does not expect the s390-like
         implementation and emits a warning. To get rid of that warning and
         provide sane CPU-to-node and CPU-to-CPU distance mappings implementat
         a minimal version of setup_per_cpu_areas()
      
       - Use kstrtobool() instead of strtobool() for re-IPL sysfs device
         attributes
      
       - Avoid unnecessary lookup of a pointer to MSI descriptor when setting
         IRQ affinity for a PCI device
      
       - Get rid of "an incompatible function type cast" warning by changing
         debug_sprintf_format_fn() function prototype so it matches the
         debug_format_proc_t function type
      
       - Remove unused info_blk_hdr__pcpus() and get_page_state() functions
      
       - Get rid of clang "unused unused insn cache ops function" warning by
         moving s390_insn definition to a private header
      
       - Get rid of clang "unused function" warning by making function
         raw3270_state_final() only available if CONFIG_TN3270_CONSOLE is
         enabled
      
       - Use kstrobool() to parse sclp_con_drop parameter to make it identical
         to the con3215_drop parameter and allow passing values like "yes" and
         "true"
      
       - Use sysfs_emit() for all SCLP sysfs show functions, which is the
         current standard way to generate output strings
      
       - Make SCLP con_drop sysfs attribute also writable and allow to change
         its value during runtime. This makes SCLP console drop handling
         consistent with the 3215 device driver
      
       - Virtual and physical addresses are indentical on s390. However, there
         is still a confusion when pointers are directly casted to physical
         addresses or vice versa. Use correct address converters
         virt_to_phys() and phys_to_virt() for s390 channel IO drivers
      
       - Support for power managemant has been removed from s390 since quite
         some time. Remove unused power managemant code from the appldata
         device driver
      
       - Allow memory tools like KASAN see memory accesses from the checksum
         code. Switch to GENERIC_CSUM if KASAN is enabled, just like x86 does
      
       - Add support of ECKD DASDs disks so it could be used as boot and dump
         devices
      
       - Follow checkpatch recommendations and use octal values instead of
         S_IRUGO and S_IWUSR for dump device attributes in sysfs
      
       - Changes to vx-insn.h do not cause a recompile of C files that use
         asm(".include \"asm/vx-insn.h\"\n") magic to access vector
         instruction macros from inline assemblies. Add wrapper include header
         file to avoid this problem
      
       - Use vector instruction macros instead of byte patterns to increase
         register validation routine readability
      
       - The current machine check register validation handling does not take
         into account various scenarios and might lead to killing a wrong user
         process or potentially ignore corrupted FPU registers. Simplify logic
         of the machine check handler and stop the whole machine if the
         previous context was kerenel mode. If the previous context was user
         mode, kill the current task
      
       - Introduce sclp_emergency_printk() function which can be used to emit
         a message in emergency cases. It is supposed to be used in cases
         where regular console device drivers may not work anymore, e.g.
         unrecoverable machine checks
      
         Keep the early Service-Call Control Block so it can also be used
         after initdata has been freed to allow sclp_emergency_printk()
         implementation
      
       - In case a system will be stopped because of an unrecoverable machine
         check error print the machine check interruption code to give a hint
         of what went wrong
      
       - Move storage error checking from the assembly entry code to C in
         order to simplify machine check handling. Enter the handler with DAT
         turned on, which simplifies the entry code even more
      
       - The machine check extended save areas are allocated using a private
         "nmi_save_areas" slab cache which guarantees a required power-of-two
         alignment. Get rid of that cache in favour of kmalloc()

      Pull ARM SoC DT updates from Arnd Bergmann:
       "The devicetree changes contain exactly 1000 non-merge changesets,
        including a number of new arm64 SoC variants from Qualcomm and Apple,
        as well as the Renesas r9a07g043f/u chip in both arm64 and riscv
        variants.
      
        While we have occasionally merged support for non-arm SoCs in the
        past, this is now the normal path for riscv devicetree files.
      
        The most notable changes, by SoC platform, are:
      
         - The Apple T6000 (M1 Pro), T6001 (M1 Max) and T6002 (M1 Ultra) chips
           now have initial support. This is particularly nice as I am typing
           this on a T6002 Mac Studio with only a small number of driver
           patches.
      
         - Qualcomm MSM8996 Pro (Snapdragon 821), SM6115 (Snapdragon 662),
           SM4250 (Snapdragon 460), SM6375 (Snapdragon 695), SDM670
           (Snapdragon 670), MSM8976 (Snapdragon 652) and MSM8956 (Snapdragon
           650) are all mobile phone chips that are closely related to others
           we already support.
      
           Adding those helps support more phones and we add several models
           from Sony (Xperia 10 IV, 5 IV, X, and X compact), OnePlus (One, 3,
           3T, and Nord N100), Xiaomi (Poco F1, Mi6), Huawei (Watch) and
           Google (Pixel 3a).
      
           There are also new variants of the Herobrine and Trogdor chromebook
           motherboards. SA8540P is an automotive SoC used in the Qdrive-3
           development platform
      
         - Rockchips gains no new SoC variants, but a lot of new boards: three
           mobile gaming systems based on RK3326 Odroid-Go/rg351 family, two
           more Anbernic gaming systems based on RK3566 and a number of other
           RK356x based single-board computers.
      
         - Renesas RZ/G2UL (r9a07g043) was already supported for arm64, but as
           the newly added RZ/Five is based on the same design, this now gets
           reorganized in order to share most of the dts description between
           the two and add the RZ/Five SMARC EVK board support.
      
        Aside from that, there are the usual changes all over the tree:
      
         - New boards on other platforms contain two ASpeed BMC users, two
           Broadcom based Wifi routers, Zyxel NSA310S NAS, the i.MX6 based
           Kobo Aura2 ebook reader, two i.MX8 based development boards, two
           Uniphier Pro5 development boards, the STM32MP1 testbench board from
           DHCOR, the TI K3 based BeagleBone AI-64 board, and the Mediatek
           Helio X10 based Sony Xperia M5 phone.
      
         - The Starfive JH7100 source gets reorganized in order to support the
           VisionFive V1 board.
      
         - Minor updates and cleanups for Intel SoCFPGA, Marvell PXA168, TI,
           ST, NXP, Apple, Broadcom, Juno, Marvell MVEBU, at91, nuvoton,
           Tegra, Mediatek, Renesas, Hisilicon, Allwinner, Samsung, ux500,
           spear, ... The treewide cleanups now have a lot of fixes for cache
           nodes and other binding violoations.
      
         - Somewhat larger sets of reworks for NVIDIA Tegra, Qualcomm and
           Renesas platforms, adding a lot more on-chip device support
      
         - A rework of the way that DTB overlays are built"

       "There are few major updates in the SoC specific drivers, mainly the

      Pull arm64 updates from Will Deacon:
       "The highlights this time are support for dynamically enabling and
        disabling Clang's Shadow Call Stack at boot and a long-awaited
        optimisation to the way in which we handle the SVE register state on
        system call entry to avoid taking unnecessary traps from userspace.
      
        Summary:
      
        ACPI:
         - Enable FPDT support for boot-time profiling
         - Fix CPU PMU probing to work better with PREEMPT_RT
         - Update SMMUv3 MSI DeviceID parsing to latest IORT spec
         - APMT support for probing Arm CoreSight PMU devices
      
        CPU features:
         - Advertise new SVE instructions (v2.1)
         - Advertise range prefetch instruction
         - Advertise CSSC ("Common Short Sequence Compression") scalar
           instructions, adding things like min, max, abs, popcount
         - Enable DIT (Data Independent Timing) when running in the kernel
         - More conversion of system register fields over to the generated
           header
      
        CPU misfeatures:
         - Workaround for Cortex-A715 erratum #2645198
      
        Dynamic SCS:
         - Support for dynamic shadow call stacks to allow switching at
           runtime between Clang's SCS implementation and the CPU's pointer
           authentication feature when it is supported (complete with scary
           DWARF parser!)
      
        Tracing and debug:
         - Remove static ftrace in favour of, err, dynamic ftrace!
         - Seperate 'struct ftrace_regs' from 'struct pt_regs' in core ftrace
           and existing arch code
         - Introduce and implement FTRACE_WITH_ARGS on arm64 to replace the
           old FTRACE_WITH_REGS
         - Extend 'crashkernel=' parameter with default value and fallback to
           placement above 4G physical if initial (low) allocation fails
      
        SVE:
         - Optimisation to avoid disabling SVE unconditionally on syscall
           entry and just zeroing the non-shared state on return instead
      
        Exceptions:
         - Rework of undefined instruction handling to avoid serialisation on
           global lock (this includes emulation of user accesses to the ID
           registers)
      
        Perf and PMU:
         - Support for TLP filters in Hisilicon's PCIe PMU device
         - Support for the DDR PMU present in Amlogic Meson G12 SoCs
         - Support for the terribly-named "CoreSight PMU" architecture from
           Arm (and Nvidia's implementation of said architecture)
      
        Misc:
         - Tighten up our boot protocol for systems with memory above 52 bits
           physical
         - Const-ify static keys to satisty jump label asm constraints
         - Trivial FFA driver cleanups in preparation for v1.1 support
         - Export the kernel_neon_* APIs as GPL symbols
         - Harden our instruction generation routines against instrumentation
         - A bunch of robustness improvements to our arch-specific selftests
         - Minor cleanups and fixes all over (kbuild, kprobes, kfence, PMU, ...)"

      Pull slab updates from Vlastimil Babka:
      
       - SLOB deprecation and SLUB_TINY
      
         The SLOB allocator adds maintenance burden and stands in the way of
         API improvements [1]. Deprecate it by renaming the config option (to
         make users notice) to CONFIG_SLOB_DEPRECATED with updated help text.
         SLUB should be used instead as SLAB will be the next on the removal
         list.
      
         Based on reports from a riscv k210 board with 8MB RAM, add a
         CONFIG_SLUB_TINY option to minimize SLUB's memory usage at the
         expense of scalability. This has resolved the k210 regression [2] so
         in case there are no others (that wouldn't be resolvable by further
         tweaks to SLUB_TINY) plan is to remove SLOB in a few cycles.
      
         Existing defconfigs with CONFIG_SLOB are converted to
         CONFIG_SLUB_TINY.
      
       - kmalloc() slub_debug redzone improvements
      
         A series from Feng Tang that builds on the tracking or requested size
         for kmalloc() allocations (for caches with debugging enabled) added
         in 6.1, to make redzone checks consider the requested size and not
         the rounded up one, in order to catch more subtle buffer overruns.
         Includes new slub_kunit test.
      
       - struct slab fields reordering to accomodate larger rcu_head
      
         RCU folks would like to grow rcu_head with debugging options, which
         breaks current struct slab layout's assumptions, so reorganize it to
         make this possible.
      
       - Miscellaneous improvements/fixes:
           - __alloc_size checking compiler workaround (Kees Cook)
           - Optimize and cleanup SLUB's sysfs init (Rasmus Villemoes)

      Pull printk updates from Petr Mladek:
      
       - Add NMI-safe SRCU reader API. It uses atomic_inc() instead of
         this_cpu_inc() on strong load-store architectures.
      
       - Introduce new console_list_lock to synchronize a manipulation of the
         list of registered consoles and their flags.
      
         This is a first step in removing the big-kernel-lock-like behavior of
         console_lock(). This semaphore still serializes console->write()
         calbacks against:
      
            - each other. It primary prevents potential races between early
              and proper console drivers using the same device.
      
            - suspend()/resume() callbacks and init() operations in some
              drivers.
      
            - various other operations in the tty/vt and framebufer
              susbsystems. It is likely that console_lock() serializes even
              operations that are not directly conflicting with the
              console->write() callbacks here. This is the most complicated
              big-kernel-lock aspect of the console_lock() that will be hard
              to untangle.
      
       - Introduce new console_srcu lock that is used to safely iterate and
         access the registered console drivers under SRCU read lock.
      
         This is a prerequisite for introducing atomic console drivers and
         console kthreads. It will reduce the complexity of serialization
         against normal consoles and console_lock(). Also it should remove the
         risk of deadlock during critical situations, like Oops or panic, when
         only atomic consoles are registered.
      
       - Check whether the console is registered instead of enabled on many
         locations. It was a historical leftover.
      
       - Cleanly force a preferred console in xenfb code instead of a dirty
         hack.
      
       - A lot of code and comment clean ups and improvements.

       "The main change here is to add the new locks_inode_context helper, and
        convert all of the places that dereference inode->i_flctx directly to
        use that instead.
      
        There is a new helper to indicate whether any locks are held on an
        inode. This is mostly for Ceph but may be usable elsewhere too.
      
        Andi Kleen requested that we print the PID when the LOCK_MAND warning
        fires, to help track down applications trying to use it.
      
        Finally, we added some new warnings to some of the file locking
        functions that fire when the ->fl_file and filp arguments differ. This
        helped us find some long-standing bugs in lockd. Patches for those are
        in Chuck Lever's tree and should be in his v6.2 PR. After that patch,
        people using NFSv2/v3 locking may see some warnings fire until those

           atomisp: make hive_int8 explictly signed").
      
         - Finally, there's the change to actually enable -funsigned-char
           ("kbuild: treat char as always unsigned") and then the removal of
           some no longer useful !__CHAR_UNSIGNED__ selftest code ("lib:
           assume char is unsigned").
      
        The various fixes were found with a combination of diffing objdump
        output, a large variety of Coccinelle scripts, and plain old grep. In
        the end, things didn't seem as bad as I feared they would. But of
        course, it's also possible I missed things.
      
        However, this has been in linux-next for basically an entire cycle
        now, so I'm not overly worried. I've also been daily driving this on
        my laptop for all of 6.1. Still, this series, and the ones sent for
        6.1 don't total in quantity to what I thought it'd be, so I will be on
        the lookout for breakage.
      
        We could receive a few reports that are quickly fixable. Hopefully we
        won't receive a barrage of reports that would result in a revert. And
        just maybe we won't receive any reports at all and nobody will even
        notice. Knock on wood"

      Pull RCU updates from Paul McKenney:
      
       - Documentation updates. This is the second in a series from an ongoing
         review of the RCU documentation.
      
       - Miscellaneous fixes.
      
       - Introduce a default-off Kconfig option that depends on RCU_NOCB_CPU
         that, on CPUs mentioned in the nohz_full or rcu_nocbs boot-argument
         CPU lists, causes call_rcu() to introduce delays.
      
         These delays result in significant power savings on nearly idle
         Android and ChromeOS systems. These savings range from a few percent
         to more than ten percent.
      
         This series also includes several commits that change call_rcu() to a
         new call_rcu_hurry() function that avoids these delays in a few
         cases, for example, where timely wakeups are required. Several of
         these are outside of RCU and thus have acks and reviews from the
         relevant maintainers.
      
       - Create an srcu_read_lock_nmisafe() and an srcu_read_unlock_nmisafe()
         for architectures that support NMIs, but which do not provide
         NMI-safe this_cpu_inc(). These NMI-safe SRCU functions are required
         by the upcoming lockless printk() work by John Ogness et al.
      
       - Changes providing minor but important increases in torture test
         coverage for the new RCU polled-grace-period APIs.
      
       - Changes to torturescript that avoid redundant kernel builds, thus
         providing about a 30% speedup for the torture.sh acceptance test.
