- The removal of the Assisted-by requirement, as concluded at the

- A new "testdocs" make target to run the documentation unit tests

now maintenance for the traditional Chinese translations as well

...and the usual pile of minor fixes, documentation updates, etc"

ASoC: Fixes for v7.3

There's a relatively large block of fixes for errors in register field
definitions here, resulting from an audit done after review of a prior
series. The fixes themselves are very small and can be directly checked
against the datasheets. Other than that we've got some driver specific
fixes, the AMD fix is a little large but fixes a clear issue and won't
affect other systems.

regmap: Fix cache lifecycle locking and teardown

Michael Reeves <michael.reeves077@gmail.com> says:

Fix an "Invalid wait context" lockdep warning during Apple GPIO probe and
correct debugfs ordering during cache teardown.

Tested on Apple M3 MacBook Air (T8122):

- All 4 GPIO controllers probe successfully with lockdep enabled.
- The "Invalid wait context" warning no longer occurs.
- The regmap KUnit suite passes and lockdep remains enabled.

ASoC: Fix controls that write another control's bits

HyeongJun An <sammiee5311@gmail.com> says:

In the es8316 thread Mark suggested checking at registration time for
controls whose register fields overlap [1]. Before adding such a check,
I wanted to see what it would find in the tree today.

A script expanded the control tables of every ASoC driver built by
allmodconfig and looked for two controls in one table whose register
fields overlap. It found 80 pairs in 33 drivers. Most are real bugs.
The rest are deliberate, where two names drive the same field, such as
the AC and DRC mode thresholds in sta32x.

This series fixes six that I could confirm against the vendor
datasheet. In each one, writing a control changes a different control,
and the bits it should own cannot be reached. Most date back to the
first version of the driver.

One more is left out on purpose. The cs42l56 ADC Mute Switch writes the
ADC invert bits. The real mute bits are also written by the
cs42l56_mute() callback on every stream start and stop, so moving the
control there would let the stream mute override it. I am not sure
whether you would rather move it or drop it.

I have none of this hardware, so these are checked against the
datasheets only. More fixes, checked against the register headers,
and the registration time check would follow.

docs: Makefile: Add a testdocs target for the documentation unit tests

tools/unittests/run.py discovers and runs the unit tests there (which
are primarily documentation tools), but nothing in the build calls it,
so the tests are only run by whoever remembers that the script is there.

Give it a target, next to the other checks that need no Sphinx. The name
ends in "docs", so it matches the "%docs" pattern already in
no-dot-config-targets and runs without a configured tree, and it sets
PYTHONPYCACHEPREFIX as the other Python targets here do, to keep
__pycache__ directories out of the source tree.

Ran 121 tests

with "make dochelp" listing it between refcheckdocs and cleandocs.

Merge patch series "lazy bounce buffering for checksummed reads v3"

Christoph Hellwig <hch@lst.de> says:

This series improves performance and resource usage for reads from
devices that require stable pages due to checksumming on XFS.

Currently XFS unconditionally bounce buffers reads on such devices to
prevent user modifications to the buffer from corrupting the data,
leading to checksum failures.

This uses DRAM bandwidth and CPU cycles for copies that are not needed
most of the time, and due to the use of a bio_vec for the bounce
buffer to smaller than wanted and unaligned I/O sizes when using 4k
user pages (i.e. 1MB-4k I/O).

This series addresses this by reading without the bounce buffer first,
and then only allocating a buffer and reading into that again on an
initial checksum failure. To accommodate for rare (or hypothetical?)
applications that have legitimate needs to frequently modify in-flight
buffers, a sysfs know is provided to revert to the old behavior.

NOTE/QUESTION TO SUBSYSTEM MAINTAINERS: The patches in this series are
split over 3 subsystems, and I'd love to hear from the maintainers
about their preferences for merging this.

- Invalidate the ITS translation cache when the guest changes the
base address of the ITS tables (Fuad Tabba)

- Skip saving ITS devices with device IDs that are out-of-bounds
rather than failing the entire ITS save ioctl (Fuad Tabba)

- Close race between VM teardown and invalidations of nested MMUs
when handling MMU operations that are allowed to block
(Lorenzo Stoakes)

- Various fixes for the handling of the host's untrusted SVE
configuration in pKVM (Fuad Tabba)

- Make sure that empty SMCCC ranges based at 0 are rejected by the
kvm_smccc_set_filter() (Karl Mehltretter)

- Revoke the host mapping for pKVM's private stack pages, along
with a new sanity check that all mappings in the hyp's private
VA range have been correctly marked as hyp-owned (Fuad Tabba)

- Lifetime fixes for the array of shadow stage-2 MMUs, ensuring that
concurrent vCPU initialization cannot relocate in-use MMUs. Defer
the freeing of shadow stage-2 MMUs to the point that no other users
(e.g. MMU notifier) could reference them (Marc Zyngier)

- Drop useless WARN when rejecting an unsupported ioctl for pKVM
(Fuad Tabba)

- Fix the steal_time selftest to install correctly-sized mappings for
non-4K hosts (Sebastian Ott)

- Correct mapping of fine-grained trap for GCSPOPX instruction
