      Pull kvm updates from Paolo Bonzini:
       "ARM64:
      
         - Enable the per-vcpu dirty-ring tracking mechanism, together with an
           option to keep the good old dirty log around for pages that are
           dirtied by something other than a vcpu.
      
         - Switch to the relaxed parallel fault handling, using RCU to delay
           page table reclaim and giving better performance under load.
      
         - Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping
           option, which multi-process VMMs such as crosvm rely on (see merge
           commit 382b5b87: "Fix a number of issues with MTE, such as
           races on the tags being initialised vs the PG_mte_tagged flag as
           well as the lack of support for VM_SHARED when KVM is involved.
           Patches from Catalin Marinas and Peter Collingbourne").
      
         - Merge the pKVM shadow vcpu state tracking that allows the
           hypervisor to have its own view of a vcpu, keeping that state
           private.
      
         - Add support for the PMUv3p5 architecture revision, bringing support
           for 64bit counters on systems that support it, and fix the
           no-quite-compliant CHAIN-ed counter support for the machines that
           actually exist out there.
      
         - Fix a handful of minor issues around 52bit VA/PA support (64kB
           pages only) as a prefix of the oncoming support for 4kB and 16kB
           pages.
      
         - Pick a small set of documentation and spelling fixes, because no
           good merge window would be complete without those.
      
        s390:
      
         - Second batch of the lazy destroy patches
      
         - First batch of KVM changes for kernel virtual != physical address
           support
      
         - Removal of a unused function
      
        x86:
      
         - Allow compiling out SMM support
      
         - Cleanup and documentation of SMM state save area format
      
         - Preserve interrupt shadow in SMM state save area
      
         - Respond to generic signals during slow page faults
      
         - Fixes and optimizations for the non-executable huge page errata
           fix.
      
         - Reprogram all performance counters on PMU filter change
      
         - Cleanups to Hyper-V emulation and tests
      
         - Process Hyper-V TLB flushes from a nested guest (i.e. from a L2
           guest running on top of a L1 Hyper-V hypervisor)
      
         - Advertise several new Intel features
      
         - x86 Xen-for-KVM:
      
            - Allow the Xen runstate information to cross a page boundary
      
            - Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured
      
            - Add support for 32-bit guests in SCHEDOP_poll
      
         - Notable x86 fixes and cleanups:
      
            - One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).
      
            - Reinstate IBPB on emulated VM-Exit that was incorrectly dropped
              a few years back when eliminating unnecessary barriers when
              switching between vmcs01 and vmcs02.
      
            - Clean up vmread_error_trampoline() to make it more obvious that
              params must be passed on the stack, even for x86-64.
      
            - Let userspace set all supported bits in MSR_IA32_FEAT_CTL
              irrespective of the current guest CPUID.
      
            - Fudge around a race with TSC refinement that results in KVM
              incorrectly thinking a guest needs TSC scaling when running on a
              CPU with a constant TSC, but no hardware-enumerated TSC
              frequency.
      
            - Advertise (on AMD) that the SMM_CTL MSR is not supported
      
            - Remove unnecessary exports
      
        Generic:
      
         - Support for responding to signals during page faults; introduces
           new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks
      
        Selftests:
      
         - Fix an inverted check in the access tracking perf test, and restore
           support for asserting that there aren't too many idle pages when
           running on bare metal.
      
         - Fix build errors that occur in certain setups (unsure exactly what
           is unique about the problematic setup) due to glibc overriding
           static_assert() to a variant that requires a custom message.
      
         - Introduce actual atomics for clear/set_bit() in selftests
      
         - Add support for pinning vCPUs in dirty_log_perf_test.
      
         - Rename the so called "perf_util" framework to "memstress".
      
         - Add a lightweight psuedo RNG for guest use, and use it to randomize
           the access pattern and write vs. read percentage in the memstress
           tests.
      
         - Add a common ucall implementation; code dedup and pre-work for
           running SEV (and beyond) guests in selftests.
      
         - Provide a common constructor and arch hook, which will eventually
           be used by x86 to automatically select the right hypercall (AMD vs.
           Intel).
      
         - A bunch of added/enabled/fixed selftests for ARM64, covering
           memslots, breakpoints, stage-2 faults and access tracking.
      
         - x86-specific selftest changes:
      
            - Clean up x86's page table management.
      
            - Clean up and enhance the "smaller maxphyaddr" test, and add a
              related test to cover generic emulation failure.
      
            - Clean up the nEPT support checks.
      
            - Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.
      
            - Fix an ordering issue in the AMX test introduced by recent
              conversions to use kvm_cpu_has(), and harden the code to guard
              against similar bugs in the future. Anything that tiggers
              caching of KVM's supported CPUID, kvm_cpu_has() in this case,
              effectively hides opt-in XSAVE features if the caching occurs
              before the test opts in via prctl().
      
        Documentation:
      
         - Remove deleted ioctls from documentation
      
         - Clean up the docs for the x86 MSR filter.
      
         - Various fixes"

      Pull gpio updates from Bartosz Golaszewski:
       "We have a new GPIO multiplexer driver, bunch of driver updates and
        refactoring in the core GPIO library.
      
        GPIO core:
         - teach gpiolib to work with software nodes for HW description
         - remove ARCH_NR_GPIOS treewide as we no longer impose any limit on
           the number of GPIOS since the allocation became entirely dynamic
         - add support for HW quirks for Cirrus CS42L56 codec, Marvell NFC
           controller, Freescale PCIe and Ethernet controller, Himax LCDs and
           Mediatek mt2701
         - refactor OF quirk code
         - some general refactoring of the OF and ACPI code, adding new
           helpers, minor tweaks and fixes, making fwnode usage consistent
           etc.
      
        GPIO uAPI:
         - fix an issue where the user-space can trigger a NULL-pointer
           dereference in the kernel by opening a device file, forcing a
           driver unbind and then calling one of the syscalls on the
           associated file descriptor
      
        New drivers:
         - add gpio-latch: a new GPIO multiplexer based on latches connected
           to other GPIOs
      
        Driver updates:
         - convert i2c GPIO expanders to using .probe_new()
         - drop the gpio-sta2x11 driver
         - factor out common code for the ACCES IDIO-16 family of controllers
           and use this new library wherever applicable in drivers
         - add DT support to gpio-hisi
         - allow building gpio-davinci as a module and increase its maxItems
           property
         - add support for a new model to gpio-pca9570
         - other minor changes to various drivers"

      Pull f2fs updates from Jaegeuk Kim:
       "In this round, we've added two features: F2FS_IOC_START_ATOMIC_REPLACE
        and a per-block age-based extent cache.
      
        F2FS_IOC_START_ATOMIC_REPLACE is a variant of the previous atomic
        write feature which guarantees a per-file atomicity. It would be more
        efficient than AtomicFile implementation in Android framework.
      
        The per-block age-based extent cache implements another type of extent
        cache in memory which keeps the per-block age in a file, so that block
        allocator could split the hot and cold data blocks more accurately.
      
        Enhancements:
         - introduce F2FS_IOC_START_ATOMIC_REPLACE
         - refactor extent_cache to add a new per-block-age-based extent cache support
         - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs
         - add proc entry to show discard_plist info
         - optimize iteration over sparse directories
         - add barrier mount option
      
        Bug fixes:
         - avoid victim selection from previous victim section
         - fix to enable compress for newly created file if extension matches
         - set zstd compress level correctly
         - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot
         - correct i_size change for atomic writes
         - allow to read node block after shutdown
         - allow to set compression for inlined file
         - fix gc mode when gc_urgent_high_remaining is 1
         - should put a page when checking the summary info

      Pull x86 core updates from Borislav Petkov:
      
       - Add the call depth tracking mitigation for Retbleed which has been
         long in the making. It is a lighterweight software-only fix for
         Skylake-based cores where enabling IBRS is a big hammer and causes a
         significant performance impact.
      
         What it basically does is, it aligns all kernel functions to 16 bytes
         boundary and adds a 16-byte padding before the function, objtool
         collects all functions' locations and when the mitigation gets
         applied, it patches a call accounting thunk which is used to track
         the call depth of the stack at any time.
      
         When that call depth reaches a magical, microarchitecture-specific
         value for the Return Stack Buffer, the code stuffs that RSB and
         avoids its underflow which could otherwise lead to the Intel variant
         of Retbleed.
      
         This software-only solution brings a lot of the lost performance
         back, as benchmarks suggest:
