Scheduler updates in this cycle are:
- Improve the scalability of the CFS bandwidth unthrottling logic
with large number of CPUs.
- Fix & rework various cpuidle routines, simplify interaction with
the generic scheduler code. Add __cpuidle methods as noinstr to
objtool's noinstr detection and fix boatloads of cpuidle bugs & quirks.
- Add new ABI: introduce MEMBARRIER_CMD_GET_REGISTRATIONS,
to query previously issued registrations.
- Limit scheduler slice duration to the sysctl_sched_latency period,
to improve scheduling granularity with a large number of SCHED_IDLE
tasks.
- Debuggability enhancement on sys_exit(): warn about disabled IRQs,
but also enable them to prevent a cascade of followup problems and
repeat warnings.
- Fix the rescheduling logic in prio_changed_dl().
- Micro-optimize cpufreq and sched-util methods.
- Micro-optimize ttwu_runnable()
- Micro-optimize the idle-scanning in update_numa_stats(),
select_idle_capacity() and steal_cookie_task().
- Update the RSEQ code & self-tests
- Constify various scheduler methods
- Remove unused methods
- Refine __init tags
- Documentation updates
- ... Misc other cleanups, fixes

SoC: DT changes for 6.3
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.

ARM: defconfigs for 6.3

ARM: 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 |

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
- misc cleanups, spelling fixes
Other code:
- block: export bio_split_rw
- iomap: remove IOMAP_F_ZONE_APPEND"

fsverity updates for 6.3
Fix the longstanding implementation limitation that fsverity was only supported when the Merkle tree block size, filesystem block size, and PAGE_SIZE were all equal. 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. Also update fs/verity/ to support verifying data from large folios. There's also a similar patch for fs/crypto/, to support decrypting data from large folios, which I'm including in this pull request to avoid a merge conflict between the fscrypt and fsverity branches. There will be a merge conflict in fs/buffer.c with some of the foliation work in the mm tree.

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.
Summary:
- Add per-cpu kthreads for low-latency decompression for Android use
cases
- Get rid of tagged pointer helpers since they are rarely used now
- Several code cleanups to reduce codebase

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"

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.

"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".

A single fix for x86:
Revert the recent change to the MTRR code which aimed to support
SEV-SNP guests on Hyper-V. It cuased a regression on XEN Dom0
kernels.
The underlying issue of MTTR (mis)handling in the x86 code needs some
deeper investigation and is definitely not 6.2 material.

nilfs2: fix underflow in second superblock position calculations
Macro NILFS_SB2_OFFSET_BYTES, which computes the position of the second
superblock, underflows when the argument device size is less than 4096
bytes. Therefore, when using this macro, it is necessary to check in
advance that the device size is not less than a lower limit, or at least
that underflow does not occur.
The current nilfs2 implementation lacks this check, causing out-of-bound
block access when mounting devices smaller than 4096 bytes:
I/O error, dev loop0, sector 36028797018963960 op 0x0:(READ) flags 0x0
phys_seg 1 prio class 2
NILFS (loop0): unable to read secondary superblock (blocksize = 1024)
In addition, when trying to resize the filesystem to a size below 4096
bytes, this underflow occurs in nilfs_resize_fs(), passing a huge number
of segments to nilfs_sufile_resize(), corrupting parameters such as the
number of segments in superblocks. This causes excessive loop iterations
in nilfs_sufile_resize() during a subsequent resize ioctl, causing
semaphore ns_segctor_sem to block for a long time and hang the writer
thread:

hugetlb: check for undefined shift on 32 bit architectures
Users can specify the hugetlb page size in the mmap, shmget and
memfd_create system calls. This is done by using 6 bits within the flags
argument to encode the base-2 logarithm of the desired page size. The
routine hstate_sizelog() uses the log2 value to find the corresponding
hugetlb hstate structure. Converting the log2 value (page_size_log) to
potential hugetlb page size is the simple statement:
1UL << page_size_log
Because only 6 bits are used for page_size_log, the left shift can not be
greater than 63. This is fine on 64 bit architectures where a long is 64
bits. However, if a value greater than 31 is passed on a 32 bit
architecture (where long is 32 bits) the shift will result in undefined
behavior. This was generally not an issue as the result of the undefined
shift had to exactly match hugetlb page size to proceed.
Recent improvements in runtime checking have resulted in this undefined
behavior throwing errors such as reported below.
Fix by comparing page_size_log to BITS_PER_LONG before doing shift.

mm/migrate: fix wrongly apply write bit after mkdirty on sparc64
Nick Bowler reported another sparc64 breakage after the young/dirty
persistent work for page migration (per "Link:" below). That's after a
similar report [2].
It turns out page migration was overlooked, and it wasn't failing before
because page migration was not enabled in the initial report test
environment.
David proposed another way [2] to fix this from sparc64 side, but that
patch didn't land somehow. Neither did I check whether there's any other
arch that has similar issues.
Let's fix it for now as simple as moving the write bit handling to be
after dirty, like what we did before.
Note: this is based on mm-unstable, because the breakage was since 6.1 and
we're at a very late stage of 6.2 (-rc8), so I assume for this specific
case we should target this at 6.3.

Use radix_tree_maybe_preload() which does preload only if
gfpflags_allow_blocking() is true but also takes the lock. Therefore,
unconditionally calling radix_tree_preload_end() should not create any
issues and the message disappears.
