      Pull SoC DT updates from Arnd Bergmann:
       "About a quarter of the changes are for 32-bit arm, mostly filling in
        device support for existing machines and adding minor cleanups, mostly
        for Qualcomm and Samsung based machines.
      
        Two new 32-bit SoCs are added, both are quad-core Cortex-A7 chips from
        Rockchips that have been around for a while but were lacking kernel
        support so far: RV1126 is a Vision SoC with an NPU and is used in the
        Edgeble Neural Compute Module 2(Neu2) board, while RK3128 is design
        for TV boxes and so far only comes with a dts for its refernece
        design.
      
        The other 32-bit boards that were added are two ASpeed AST2600 based
        BMC boards, the Microchip sam9x60_curiosity development board (Armv5
        based!), the Enclustra PE1 FPGA-SoM baseboard, and a few more boards
        for i.MX53 and i.MX6ULL.
      
        On the RISC-V side, there are fewer patches, but a total of ten new
        single-board computers based on variations of the Allwinner D1/T113
        chip, plus one more board based on Microchip Polarfire.
      
        As usual, arm64 has by far the most changes here, with over 700
        non-merge changesets, among them over 400 alone for Qualcomm. The
        newly added SoCs this time are all recent high-end embedded SoCs for
        various markets, each on comes with support for its reference board:
      
         - Qualcomm SM8550 (Snapdragon 8 Gen 2) for mobile phones
         - Qualcomm QDU1000/QRU1000 5G RAN platform
         - Rockchips RK3588/RK3588s for tablets, chromebooks and SBCs
         - TI J784S4 for industrial and automotive applications
      
        In total, there are 46 new arm64 machines:
         - Reference platforms for each of the five new SoCs
         - Three Amlogic based development boards
         - Six embedded machines based on NXP i.MX8MM and i.MX8MP
         - The Mediatek mt7986a based Banana Pi R3 router
         - Six tablets based on Qualcomm MSM8916 (Snapdragon 410), SM6115
           (Snapdragon 662) and SM8250 (Snapdragon 865)
         - Two LTE dongles, also based on MSM8916
         - Seven mobile phones, based on Qualcomm MSM8953 (Snapdragon 610),
           SDM450 and SDM632
         - Three chromebooks based on Qualcomm SC7280 (Snapdragon 7c)
         - Nine development boards based on Rockchips RK3588, RK3568, RK3566
           and RK3328.
         - Five development machines based on TI K3 (AM642/AM654/AM68/AM69)
      
        The cleanup of dtc warnings continues across all platforms, adding to
        the total number of changes"

      Pull ARM SoC boardfile updates from Arnd Bergmann
       "Unused boardfile removal for 6.3
      
        This is a follow-up to the deprecation of most of the old-style board
        files that was merged in linux-6.0, removing them for good.
      
        This branch is almost exclusively dead code removal based on those
        annotations. Some device driver removals went through separate
        subsystem trees, but the majority is in the same branch, in order to
        better handle dependencies between the patches and avoid breaking
        bisection.
      
        Unfortunately that leads to merge conflicts against other changes in
        the subsystem trees, but they should all be trivial to resolve by
        removing the files.
      
        See commit 7d0d3fa7 ("Merge tag 'arm-boardfiles-6.0' of
        git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
        description of which machines were marked unused and are now removed.
      
        The only removals that got postponed are Terastation WXL (mv78xx0) and
        Jornada720 (StrongARM1100), which turned out to still have potential
        users"

       "The usual mix of performance improvements and new features.
      
        The core change is reworking how checksums are processed, with
        followup cleanups and simplifications. There are two minor changes in
        block layer and iomap code.
      
        Features:
      
         - block group allocation class heuristics:
            - pack files by size (up to 128k, up to 8M, more) to avoid
              fragmentation in block groups, assuming that file size and life
              time is correlated, in particular this may help during balance
            - with tracepoints and extensible in the future
      
        Performance:
      
         - send: cache directory utimes and only emit the command when
           necessary
            - speedup up to 10x
            - smaller final stream produced (no redundant utimes commands
              issued)
            - compatibility not affected
      
         - fiemap: skip backref checks for shared leaves
            - speedup 3x on sample filesystem with all leaves shared (e.g. on
              snapshots)
      
         - micro optimized b-tree key lookup, speedup in metadata operations
           (sample benchmark: fs_mark +10% of files/sec)
      
        Core changes:
      
         - change where checksumming is done in the io path:
            - checksum and read repair does verification at lower layer
            - cascaded cleanups and simplifications
      
         - raid56 refactoring and cleanups
      
        Fixes:
      
         - sysfs: make sure that a run-time change of a feature is correctly
           tracked by the feature files
      
         - scrub: better reporting of tree block errors
      
        Other:
      
         - locally enable -Wmaybe-uninitialized after fixing all warnings
      
         - misc cleanups, spelling fixes
      
        Other code:
      
         - block: export bio_split_rw
      
         - iomap: remove IOMAP_F_ZONE_APPEND"

       "Fix the longstanding implementation limitation that fsverity was only
        supported when the Merkle tree block size, filesystem block size, and

        Specifically, add support for Merkle tree block sizes less than
        PAGE_SIZE, and make ext4 support fsverity on filesystems where the
        filesystem block size is less than PAGE_SIZE.
      
        Effectively, this means that fsverity can now be used on systems with
        non-4K pages, at least on ext4. These changes have been tested using
        the verity group of xfstests, newly updated to cover the new code
        paths.

        workqueue latencies are not quite good for production on many aarch64

      Pull vfs hardening update from Christian Brauner:
       "Jan pointed out that during shutdown both filp_close() and super block
        destruction will use basic printk logging when bugs are detected. This
        causes issues in a few scenarios:
      
         - Tools like syzkaller cannot figure out that the logged message
           indicates a bug.
      
         - Users that explicitly opt in to have the kernel bug on data
           corruption by selecting CONFIG_BUG_ON_DATA_CORRUPTION should see
           the kernel crash when they did actually select that option.
      
         - When there are busy inodes after the superblock is shut down later
           access to such a busy inodes walks through freed memory. It would
           be better to cleanly crash instead.
      
        All of this can be addressed by using the already existing
        CHECK_DATA_CORRUPTION() macro in these places when kernel bugs are
        detected. Its logging improvement is useful for all users.
      
        Otherwise this only has a meaningful behavioral effect when users do
        select CONFIG_BUG_ON_DATA_CORRUPTION which means this is backward
        compatible for regular users"

      Pull vfs idmapping updates from Christian Brauner:
      
       - Last cycle we introduced the dedicated struct mnt_idmap type for
         mount idmapping and the required infrastucture in 256c8aed ("fs:
         introduce dedicated idmap type for mounts"). As promised in last
         cycle's pull request message this converts everything to rely on
         struct mnt_idmap.
      
         Currently we still pass around the plain namespace that was attached
         to a mount. This is in general pretty convenient but it makes it easy
         to conflate namespaces that are relevant on the filesystem with
         namespaces that are relevant on the mount level. Especially for
         non-vfs developers without detailed knowledge in this area this was a
         potential source for bugs.
      
         This finishes the conversion. Instead of passing the plain namespace
         around this updates all places that currently take a pointer to a
         mnt_userns with a pointer to struct mnt_idmap.
      
         Now that the conversion is done all helpers down to the really
         low-level helpers only accept a struct mnt_idmap argument instead of
         two namespace arguments.
      
         Conflating mount and other idmappings will now cause the compiler to
         complain loudly thus eliminating the possibility of any bugs. This
         makes it impossible for filesystem developers to mix up mount and
         filesystem idmappings as they are two distinct types and require
         distinct helpers that cannot be used interchangeably.
      
         Everything associated with struct mnt_idmap is moved into a single
         separate file. With that change no code can poke around in struct
         mnt_idmap. It can only be interacted with through dedicated helpers.
         That means all filesystems are and all of the vfs is completely
         oblivious to the actual implementation of idmappings.
      
         We are now also able to extend struct mnt_idmap as we see fit. For
         example, we can decouple it completely from namespaces for users that
         don't require or don't want to use them at all. We can also extend
         the concept of idmappings so we can cover filesystem specific
         requirements.
      
         In combination with the vfs{g,u}id_t work we finished in v6.2 this
         makes this feature substantially more robust and thus difficult to
         implement wrong by a given filesystem and also protects the vfs.
      
       - Enable idmapped mounts for tmpfs and fulfill a longstanding request.
      
         A long-standing request from users had been to make it possible to
         create idmapped mounts for tmpfs. For example, to share the host's
         tmpfs mount between multiple sandboxes. This is a prerequisite for
         some advanced Kubernetes cases. Systemd also has a range of use-cases
         to increase service isolation. And there are more users of this.
      
         However, with all of the other work going on this was way down on the
         priority list but luckily someone other than ourselves picked this
         up.
      
         As usual the patch is tiny as all the infrastructure work had been

         xfstests during the v6.3 development cycle. This should add a slew of

        Instead of having special routines and grabbing the i_version field
        directly out of the inode in some cases, we've moved most of the
        handling into the various filesystems' getattr operations. As a bonus,
        this makes ceph's change attribute usable by knfsd as well.
      
        This should pave the way for future work to make this value queryable
        by userland, and to make it more resilient against rolling back on a

      Merge tag 'remove-get_kernel_pages-for-6.3' of https://git.linaro.org/people/jens.wiklander/linux-tee
      
      Pull TEE update from Jens Wiklander:
       "Remove get_kernel_pages()
      
        Vmalloc page support is removed from shm_get_kernel_pages() and the
        get_kernel_pages() call is replaced by calls to get_page(). With no
        remaining callers of get_kernel_pages() the function is removed"
      
      [ This looks like it's just some random 'tee' cleanup, but the bigger
        picture impetus for this is really to to to remove historical
        confusion with mixed use of kernel virtual addresses and 'struct page'
        pointers.
      
        Kernel virtual pointers in the vmalloc space is then particularly
        confusing - both for looking up a page pointer (when trying to then
        unify a "virtual address or page" interface) and _particularly_ when
        mixed with HIGHMEM support and the kmap*() family of remapping.
      
        This is particularly true with HIGHMEM getting much less test coverage
        with 32-bit architectures being increasingly legacy targets.
      
        So we actively wanted to remove get_kernel_pages() to make sure nobody
        else used it too, and thus the 'tee' part is "finally remove last
        user".
      
        See also commit 6647e76a ("v4l2: don't fall back to follow_pfn()
        if pin_user_pages_fast() fails") for a totally different version of a
        conceptually similar "let's stop this confusion of different ways of
        referring to memory".   - Linus ]

       "Apologies for the _extremely_ late pull request here, but we had a
        'perf' (i.e. CPU PMU) regression on the Apple M1 reported on Wednesday
        [1] which was introduced by bd275681 ("perf: Rewrite core context
        handling") during the merge window.
      
        Mark and I looked into this and noticed an additional problem caused
        by the same patch, where the 'CHAIN' event (used to combine two
        adjacent 32-bit counters into a single 64-bit counter) was not being
        filtered correctly. Mark posted a series on Thursday [2] which
        addresses both of these regressions and I queued it the same day.
      
        The changes are small, self-contained and have been confirmed to fix
        the original regression.
      
        Summary:
