Pull workqueue updates from Tejun Heo:
- When per-cpu workqueue workers expire after sitting idle for too
long, they used to wake up to the CPU that they're bound to in order
to exit. This unfortunately could cause unwanted disturbances on CPUs
isolated for e.g. RT applications.
The worker exit path is restructured so that an existing worker is
unbound from its CPU before being woken up for the last time,
allowing it to migrate away from an isolated CPU for exiting.
- A couple debug improvements. Watchdog dump is made more compact and
workqueue now warns if used-after-free during the RCU grace period
after destroy_workqueue().

Core:
- Move the interrupt affinity spreading mechanism into lib/group_cpus
so it can be used for similar spreading requirements, e.g. in the
block multi-queue code
This also contains a first usecase in the block multi-queue code
which Jens asked to take along with the librarization
- Improve irqdomain locking to close a number race conditions which
can be observed with massive parallel device driver probing
- Enforce and document the semantics of disable_irq() which cannot be
invoked safely from non-sleepable context
- Move the IPI multiplexing code from the Apple AIC driver into the

Pull timer updates from Thomas Gleixner:
"Updates for timekeeping, timers and clockevent/source drivers:
Core:
- Yet another round of improvements to make the clocksource watchdog
more robust:
- Relax the clocksource-watchdog skew criteria to match the NTP
criteria.
- Temporarily skip the watchdog when high memory latencies are
detected which can lead to false-positives.
- Provide an option to enable TSC skew detection even on systems
where TSC is marked as reliable.
Sigh!
- Initialize the restart block in the nanosleep syscalls to be
directed to the no restart function instead of doing a partial
setup on entry.
This prevents an erroneous restart_syscall() invocation from
corrupting user space data. While such a situation is clearly a
user space bug, preventing this is a correctness issue and caters
to the least suprise principle.
- Ignore the hrtimer slack for realtime tasks in schedule_hrtimeout()
to align it with the nanosleep semantics.
Drivers:
- The obligatory new driver bindings for Mediatek, Rockchip and
RISC-V variants.
- Add support for the C3STOP misfeature to the RISC-V timer to handle
the case where the timer stops in deeper idle state.
- Set up a static key in the RISC-V timer correctly before first use.
- The usual small improvements and fixes all over the place"

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"

"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.

"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

Specifically, add support for Merkle tree block sizes less than

Effectively, this means that fsverity can now be used on systems with

"Jan pointed out that during shutdown both filp_close() and super block

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

Merge tag 'fs.idmapped.v6.3' of git://git./linux/kernel/git/vfs/idmapping
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
256c8aed2b42 ("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.

Vmalloc page support is removed from shm_get_kernel_pages() and the

[ 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".

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

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.

arm64: perf: reject CHAIN events at creation time
Currently it's possible for a user to open CHAIN events arbitrarily,
which we previously tried to rule out in commit:
ca2b497253ad01c8 ("arm64: perf: Reject stand-alone CHAIN events for PMUv3")
Which allowed the events to be opened, but prevented them from being
scheduled by by using an arm_pmu::filter_match hook to reject the
relevant events.
The CHAIN event filtering in the arm_pmu::filter_match hook was silently
removed in commit:
bd27568117664b8b ("perf: Rewrite core context handling")
As a result, it's now possible for users to open CHAIN events, and for
these to be installed arbitrarily.
Fix this by rejecting CHAIN events at creation time. This avoids the
creation of events which will never count, and doesn't require using the
dynamic filtering.
Attempting to open a CHAIN event (0x1e) will now be rejected:
| # ./perf stat -e armv8_pmuv3/config=0x1e/ ls
| perf
|
| Performance counter stats for 'ls':
|
| <not supported> armv8_pmuv3/config=0x1e/

| 0.
002197470 seconds time elapsed
|
| 0.
000000000 seconds user
| 0.

Other events (e.g. CPU_CYCLES / 0x11) will open as usual:
| # ./perf stat -e armv8_pmuv3/config=0x11/ ls
| perf
|
| Performance counter stats for 'ls':

arm_pmu: fix event CPU filtering
Janne reports that perf has been broken on Apple M1 as of commit:
bd27568117664b8b ("perf: Rewrite core context handling")
That commit replaced the pmu::filter_match() callback with
pmu::filter(), whose return value has the opposite polarity, with true
implying events should be ignored rather than scheduled. While an
attempt was made to update the logic in armv8pmu_filter() and
armpmu_filter() accordingly, the return value remains inverted in a
couple of cases:
* If the arm_pmu does not have an arm_pmu::filter() callback,
armpmu_filter() will always return whether the CPU is supported rather
than whether the CPU is not supported.
As a result, the perf core will not schedule events on supported CPUs,
resulting in a loss of events. Additionally, the perf core will
attempt to schedule events on unsupported CPUs, but this will be
rejected by armpmu_add(), which may result in a loss of events from
other PMUs on those unsupported CPUs.
* If the arm_pmu does have an arm_pmu::filter() callback, and
armpmu_filter() is called on a CPU which is not supported by the
arm_pmu, armpmu_filter() will return false rather than true.
As a result, the perf core will attempt to schedule events on
unsupported CPUs, but this will be rejected by armpmu_add(), which may
result in a loss of events from other PMUs on those unsupported CPUs.
This means a loss of events can be seen with any arm_pmu driver, but
with the ARMv8 PMUv3 driver (which is the only arm_pmu driver with an
arm_pmu::filter() callback) the event loss will be more limited and may
go unnoticed, which is how this issue evaded testing so far.
Fix the CPU filtering by performing this consistently in
armpmu_filter(), and remove the redundant arm_pmu::filter() callback and
armv8pmu_filter() implementation.
Commit
bd2756811766 also silently removed the CHAIN event filtering from
armv8pmu_filter(), which will be addressed by a separate patch without
using the filter callback.

ASoC: SOF: Intel: hda-dai: fix possible stream_tag leak
The HDaudio stream allocation is done first, and in a second step the
LOSIDV parameter is programmed for the multi-link used by a codec.
This leads to a possible stream_tag leak, e.g. if a DisplayAudio link
is not used. This would happen when a non-Intel graphics card is used
and userspace unconditionally uses the Intel Display Audio PCMs without
checking if they are connected to a receiver with jack controls.
We should first check that there is a valid multi-link entry to
configure before allocating a stream_tag. This change aligns the
dma_assign and dma_cleanup phases.
