      Pull ARM SoC driver updates from Arnd Bergmann:
       "A couple of subsystems have their own subsystem maintainers but choose
        to have the code merged through the soc tree as upstream, as the code
        tends to be used across multiple SoCs or has SoC specific drivers
        itself:
      
         - memory controllers:
      
           Krzysztof Kozlowski takes ownership of the drivers/memory subsystem
           and its drivers, starting out with a set of cleanup patches.
      
           A larger driver for the Tegra memory controller that was
           accidentally missed for v5.8 is now added.
      
         - reset controllers:
      
           Only minor updates to drivers/reset this time
      
         - firmware:
      
           The "turris mox" firmware driver gains support for signed firmware
           blobs The tegra firmware driver gets extended to export some debug
           information Various updates to i.MX firmware drivers, mostly
           cosmetic
      
         - ARM SCMI/SCPI:
      
           A new mechanism for platform notifications is added, among a number
           of minor changes.
      
         - optee:
      
           Probing of the TEE bus is rewritten to better support detection of
           devices that depend on the tee-supplicant user space. A new
           firmware based trusted platform module (fTPM) driver is added based
           on OP-TEE
      
         - SoC attributes:
      
           A new driver is added to provide a generic soc_device for
           identifying a machine through the SMCCC ARCH_SOC_ID firmware
           interface rather than by probing SoC family specific registers.
      
           The series also contains some cleanups to the common soc_device
           code.
      
        There are also a number of updates to SoC specific drivers, the main
        ones are:
      
         - Mediatek cmdq driver gains a few in-kernel interfaces
      
         - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
           support for additional SoC variants
      
         - The Qualcomm GENI core code gains interconnect path voting and
           performance level support, and integrating this into a number of
           device drivers.
      
         - A new driver for Samsung Exynos5800 voltage coupler for
      
         - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
           specific device drivers
      
         - Updates to the TI K3 Ring Accelerator driver"

      Pull ARM SoC DT updates from Arnd Bergmann:
       "As usual, there are many patches addressing minor issues in existing
        DTS files, such as DTC warnings, or adding support for additional
        peripherals.
      
        There are three added SoCs in existing product families:
      
         - Amazon:
      
           Alpine v3 is a 16-core Cortex-A72 SoC from Amazon's Annapurna Labs,
           otherwise known as AL73400 or first-generation Graviton, and
           following the already supported Cortex-A1`5 and Cortex-A57 based
           Alpine chips. This one is added together with the official
           Evaluation platform.
      
         - Qualcomm:
      
           The Snapdragon SDM630 platform is a family of mid-range mobile
           phone chips from 2017 based on Cortex-A53 or Kryo 260 CPUs. A total
           of five end-user products are added based on these, all Android
           phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and XA2 Ultra.
      
         - Renesas:
      
           RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G
           family, and apparently closely related to the RZ/G2N and RZ/G2M
           models we already support but has a faster GPU and additional
           on-chip peripherals. It is added along with the HopeRun HiHope
           RZ/G2H development board
      
        A small number of new boards for already supported SoCs also debut:
      
         - Allwinner sunxi:
      
           Only one new machine, revision v1.2 of the Pine64 PinePhone
           (non-Android) smartphone, containing minor changes compared to
           earlier versions.
      
         - Amlogic Meson:
      
           WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box
      
         - Aspeed:
      
           EthanolX is AMD's EPYC data center rerence platform, using an
           ASpeed AST2600 baseboard management controller.
      
         - Mediatek:
      
           Lenovo IdeaPad Duet 10.1" (kukui/krane) is a new Chromebook based
           on the MT8183 (Helio P60t) SoC.
      
         - Nvidia Tegra:
      
           ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android
           tablets from around 2012 using Tegra 3 and Tegra 2, respectively.
           Thanks to PostmarketOS, these can now run mainline kernels and
           become useful again.
      
           The Jetson Xavier NX Developer Kit uses a SoM and carrier board for
           the Tegra194, their latest 64-bit chip based on Carmel CPU cores
           and Volta graphics.
      
         - NXP i.MX:
      
           Five new boards based on the 32-bit i.MX6 series are added: The
           MYiR MYS-6ULX single-board computer, and four different models of
           industrial computers from Protonic.
      
         - Qualcomm:
      
           MikroTik RouterBoard 3011 is a rackmounted router based on the
           32-bit IPQ8064 networking SoC
      
           Three older phones get added, the Snapdragon 808 (msm8992) based
           Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running
           Windows Phone, and the Snapdragon 810 (msm8994) based Sony Xperia
           Z5.
      
         - Renesas:
      
           In addition to the HiHope RZ/G2H board mentioned above, we gain
           support for board versions 3.0 and 4.0 of the earlier RZ/G2M and
           RZ/G2N reference boards. Beacon EmbeddedWorks adds another
           SoM+Carrier development board for RZ/G2M.
      
         - Rockchips:
      
           Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it is
           based on, using the high-end 32-bit rk3288 SoC.
      
        Notable updates to existing platforms are usually for added on-chip
        peripherals, including:
      
         - ASpeed AST2xxx (various)

           Usage is mostly seamless to tooling, as the pre-existing LBR
           features are kept, but there's a couple of advantages under the

           exposure of LBR features to guest kernels, etc.

      Pull arm64 and cross-arch updates from Catalin Marinas:
       "Here's a slightly wider-spread set of updates for 5.9.
      
        Going outside the usual arch/arm64/ area is the removal of
        read_barrier_depends() series from Will and the MSI/IOMMU ID
        translation series from Lorenzo.
      
        The notable arm64 updates include ARMv8.4 TLBI range operations and
        translation level hint, time namespace support, and perf.
      
        Summary:
      
         - Removal of the tremendously unpopular read_barrier_depends()
           barrier, which is a NOP on all architectures apart from Alpha, in
           favour of allowing architectures to override READ_ONCE() and do
           whatever dance they need to do to ensure address dependencies
           provide LOAD -> LOAD/STORE ordering.
      
           This work also offers a potential solution if compilers are shown
           to convert LOAD -> LOAD address dependencies into control
           dependencies (e.g. under LTO), as weakly ordered architectures will
           effectively be able to upgrade READ_ONCE() to smp_load_acquire().
           The latter case is not used yet, but will be discussed further at
           LPC.
      
         - Make the MSI/IOMMU input/output ID translation PCI agnostic,
           augment the MSI/IOMMU ACPI/OF ID mapping APIs to accept an input ID
           bus-specific parameter and apply the resulting changes to the
           device ID space provided by the Freescale FSL bus.
      
         - arm64 support for TLBI range operations and translation table level
           hints (part of the ARMv8.4 architecture version).
      
         - Time namespace support for arm64.
      
         - Export the virtual and physical address sizes in vmcoreinfo for
           makedumpfile and crash utilities.
      
         - CPU feature handling cleanups and checks for programmer errors
           (overlapping bit-fields).
      
         - ACPI updates for arm64: disallow AML accesses to EFI code regions
           and kernel memory.
      
         - perf updates for arm64.
      
         - Miscellaneous fixes and cleanups, most notably PLT counting
           optimisation for module loading, recordmcount fix to ignore
           relocations other than R_AARCH64_CALL26, CMA areas reserved for
           gigantic pages on 16K and 64K configurations.

      Pull unicore32 removal from Mike Rapoport:
       "Remove unicore32 support.
      
        The unicore32 port do not seem maintained for a long time now, there
        is no upstream toolchain that can create unicore32 binaries and all
        the links to prebuilt toolchains for unicore32 are dead. Even
        compilers that were available are not supported by the kernel anymore.
      
        Guenter Roeck says:
          "I have stopped building unicore32 images since v4.19 since there is
           no available compiler that is still supported by the kernel. I am
           surprised that support for it has not been removed from the kernel"
      
        However, it's worth pointing out two things:
      
         - Guan Xuetao is still listed as maintainer and asked for the port to
           be kept around the last time Arnd suggested removing it two years
           ago. He promised that there would be compiler sources (presumably
           llvm), but has not made those available since.
      
         - https://github.com/gxt has patches to linux-4.9 and qemu-2.7, both
           released in 2016, with patches dated early 2019. These patches
           mainly restore a syscall ABI that was never part of mainline Linux
           but apparently used in production. qemu-2.8 removed support for
           that ABI and newer kernels (4.19+) can no longer be built with the
           old toolchain, so apparently there will not be any future updates
           to that git tree"

      userfaultfd: simplify fault handling · f9bf3522
      Linus Torvalds authored
      Instead of waiting in a loop for the userfaultfd condition to become
      true, just wait once and return VM_FAULT_RETRY.
      
      We've already dropped the mmap lock, we know we can't really
      successfully handle the fault at this point and the caller will have to
      retry anyway.  So there's no point in making the wait any more
      complicated than it needs to be - just schedule away.
      
      And once you don't have that complexity with explicit looping, you can
      also just lose all the 'userfaultfd_signal_pending()' complexity,
      because once we've set the correct process sleeping state, and don't
      loop, the act of scheduling itself will be checking if there are any
      pending signals before going to sleep.
      
      We can also drop the VM_FAULT_MAJOR games, since we'll be treating all
      retried faults as major soon anyway (series to regularize and share more
      of fault handling across architectures in a separate series by Peter Xu,
      and in the meantime we won't worry about the possible minor - I'll be
      here all week, try the veal - accounting difference).

      Pull fscrypt updates from Eric Biggers:
       "This release, we add support for inline encryption via the blk-crypto
        framework which was added in 5.8.
      
        Now when an ext4 or f2fs filesystem is mounted with '-o inlinecrypt',
        the contents of encrypted files will be encrypted/decrypted via
        blk-crypto, instead of directly using the crypto API. This model
        allows taking advantage of the inline encryption hardware that is
        integrated into the UFS or eMMC host controllers on most mobile SoCs.
      
        Note that this is just an alternate implementation; the ciphertext
        written to disk stays the same.
      
        (This pull request does *not* include support for direct I/O on
        encrypted files, which blk-crypto makes possible, since that part is
        still being discussed.)
      
        Besides the above feature update, there are also a few fixes and
        cleanups, e.g. strengthening some memory barriers that may be too
        weak.
      
        All these patches have been in linux-next with no reported issues.
        I've also tested them with the fscrypt xfstests, as usual. It's also
        been tested that the inline encryption support works with the support
        for Qualcomm and Mediatek inline encryption hardware that will be in
        the scsi pull request for 5.9. Also, several SoC vendors are already
        using a previous, functionally equivalent version of these patches"

      Pull btrfs updates from David Sterba:
       "We don't have any big feature updates this time, there are lots of
        small enhacements or fixes. A highlight perhaps is the parallel fsync
        performance improvements, numbers below.
      
        Regarding the dio/iomap that was reverted last time, the required API
        changes are likely to land in the upcoming cycle, the btrfs part will
        be updated afterwards.
      
        User visible changes:
      
         - new mount option rescue= to group all recovery-related mount
           options so we don't have many specific options, currently
           introducing only aliases for existing options, future extensions
           are in development to allow read-only mount with partially damaged
           structures:
            - usebackuproot is an alias for rescue=usebackuproot
            - nologreplay is an alias for rescue=nologreplay
      
         - start deprecation of mount option inode_cache, removal scheduled to
           v5.11
      
         - removed deprecated mount options alloc_start and subvolrootid
      
         - device stats corruption counter gets incremented when a checksum
           mismatch is found
      
         - qgroup information exported in /sys/fs/btrfs/<UUID>/qgroups/<id>
           using sysfs
      
         - add link /sys/fs/btrfs/<UUID>/bdi pointing to the associated
           backing dev info
      
         - FS_INFO ioctl enhancements:
            - add flags to request/describe newly added items
            - new item: numeric checksum type and checksum size
            - new item: generation
            - new item: metadata_uuid
      
         - seed device: with one new read-write device added, print the new
           device information in /proc/mounts
      
         - balance: detect cancellation by Ctrl-C in existing cancellation
           points
      
        Performance improvements:
      
         - optimized versions of various helpers on little-endian
           architectures, where we don't have to do LE/BE conversion from
           on-disk format
      
         - tree-log/fsync optimizations leading to lower max latency reported
           by dbench, reduced by about 12%
      
         - all chunk tree leaves are prefetched at mount time, can improve
           mount time on large (terabyte-sized) filesystems
      
         - speed up parallel fsync of files with reflinked/deduped extents,
           with jobs 16 to 1024 the throughput gets improved roughly by 50% on
           average and runtime decreased roughly by 30% on average, notable
           outlier is 128 jobs with +121.2% on throughput and -54.6% runtime
      
         - another speed up of parallel fsync, reduce number of checksum tree
           lookups and contention, the improvements start to show up with 2
           tasks with +20% throughput and -16% runtime up to 64 with +200%
           throughput and -66% runtime
      
        Core:
      
         - umount-time qgroup leak checker
      
         - qgroups
            - add a way to unreserve partial range after failure, avoiding
              some EDQUOT errors
            - improved flushing logic when EDQUOT is hit
      
         - possible EINTR interruption caused by failed reservations after
           transaction start is better handled and documented
      
         - transaction abort errors are unified to EROFS in case it's not the
           original reason of abort or we don't have other way to determine
           the reason
      
        Fixes:
      
         - make truncate succeed on a NOCOW file even if data space is
           exhausted
      
         - fix cancelling balance on filesystem with exhausted metadata space
      
         - anon block device:
            - preallocate anon bdev when subvolume is created to report
              failure early
            - shorten time the anon bdev id is allocated
            - don't allocate anon bdev for internal roots
      
         - minor memory leak in ref-verify
      
         - refuse invalid combinations of compression and NOCOW file flags
      
         - lockdep fixes, updating the device locks
      
         - remove obsolete fallback logic for block group profile adjustments
           when switching from 1 to more devices, causing allocation of
           unwanted block groups
      
        Other cleanups, refactoring, simplifications:
      
         - conversions from struct inode to struct btrfs_inode in internal
           functions
      
         - removal of unused struct members"
