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"

  I have sorted the files according to the changes to Kconfig files,
  to make it easier to check what has changed compared to the 'make

  The most notable change this time is a series from Mark Brown to add

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"

Pull btrfs updates from David Sterba:
 "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

Pull erofs updates from Gao Xiang:
 "The most noticeable feature for this cycle is per-CPU kthread
  decompression since Android use cases need low-latency I/O handling in
  order to ensure the app runtime performance, currently unbounded
  workqueue latencies are not quite good for production on many aarch64
  hardwares and thus we need to introduce a deterministic expectation
  for these. Decompression is CPU-intensive and it is sleepable for
  EROFS, so other alternatives like decompression under softirq contexts
  are not considered. More details are in the corresponding commit
  message.

  Others are random cleanups around the whole codebase and we will
  continue to clean up further in the next few months.

  Due to Lunar New Year holidays, some other new features were not
  completely reviewed and solidified as expected and we may delay them
  into the next version.

   - Add per-cpu kthreads for low-latency decompression for Android use

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
   done multiple kernel releases ago. In addition to all the tests that
   we already have I requested that Rodrigo add a dedicated tmpfs
   testsuite for idmapped mounts to xfstests. It is to be included into
   xfstests during the v6.3 development cycle. This should add a slew of
   additional tests.

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()
