ASoC: SDCA: Replace use of system_wq with system_dfl_wq
This patch continues the effort to refactor workqueue APIs, which has begun
with the changes introducing new workqueues and a new alloc_workqueue flag:
commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")
The point of the refactoring is to eventually alter the default behavior of
workqueues to become unbound by default so that their workload placement is
optimized by the scheduler.
Before that to happen after a careful review and conversion of each individual
case, workqueue users must be converted to the better named new workqueues with
no intended behaviour changes:
A jack detection work that is unscheduled or in progress while executing
the suspend handler could trigger a race condition.
Ensure state consistency by cancelling any pending work or wait for its
execution to complete before processing the suspend. Since driver
(re)enables both insert and eject interrupts on resume, there is no risk
to miss the related jack events. Therefore, flush_delayed_work() is not
required here.

The nau8821_enable_jack_detect() function was supposed to allow enabling
or disabling jack events reporting. However, once enabled, any
subsequent invocation would fail and the following splat is shown:
Introduce jdet_active flag to driver data structure and use it to
provide one-time initialization of the jack detection work queue and
related interrupt line.
Note this is also a prerequisite for additional fixes around module
unloading and suspend handling.

firmware: cs_dsp: test_bin: Run test cases on long-offset blocks
Run the patch block test cases using the new long-offset block type.
This adds a new set of parameterization that uses
cs_dsp_mock_bin_add_patch_off32() to create the patch blocks in the
test bin file.
The test cases for Halo Core with V3 file format include another
run of the tests with the new parameterization, so that the tests
are run on the standard blocks and the long-offset blocks.
This commit does not add any new cases for offsets > 0xffff.
firmware: cs_dsp: mock_bin: Add function to create long-offset patches
Add cs_dsp_mock_bin_add_patch_off32(). This is the same as
cs_dsp_mock_bin_add_patch() except that it puts the offset in the
new 32-bit offset field and modifies the block type to indicate
that it uses the long offset.
firmware: cs_dsp: mock_bin: Pass offset32 to cs_dsp_mock_bin_add_raw_block()
Add an argument to cs_dsp_mock_bin_add_raw_block() to pass a 32-bit
offset, and change the type of the existing offset argument to u16.
The cs_dsp_test_bin_error.c test uses cs_dsp_mock_bin_add_raw_block()
so it needs corresponding updates to pass 0 as the 32-bit offset.
Version 1 and 2 of the bin file format had a 16-bit offset on blocks
and the sample rate field of the blocks was not used. Version 3 adds
new block types that change the old sample rate field to be a 32-bit
offset with the old offset currently unused.
cs_dsp_mock_bin_add_raw_block() doesn't attempt to do any magic - its
purpose is to create a raw block exactly as specified by the calling
test code. So the test case can pass a value for both offset fields.
firmware: cs_dsp: test_bin: Run test cases with v3 file format
The new v3 file format has all the same functionality as the earlier
formats, so run all the existing test cases with a file type of 3.
This is only done for Halo Core because v3 files are not used with the
older ADSP cores.
Handle a new type of data block that has a 32-bit offset. These are
identical to the normal blocks except that the offset is now in the
32-bit field that was previously 'sr'.
A new file version of 3 indicates that it is mandatory to process
the long-offset blocks, so that older code without that support will
reject the file.
The original 'sr' field was never used by the driver so it has been
renamed offset32.

kselftest/harness: Use helper to avoid zero-size memset warning
When building kselftests with a toolchain that enables source
fortification (e.g., Android's build environment, which uses
-D_FORTIFY_SOURCE=3), a build failure occurs in tests that use an
empty FIXTURE().
The root cause is that an empty fixture struct results in
`sizeof(self_private)` evaluating to 0. The compiler's fortification
checks then detect the `memset()` call with a compile-time constant size
of 0, issuing a `-Wuser-defined-warnings` which is promoted to an error
by `-Werror`.
An initial attempt to guard the call with `if (sizeof(self_private) > 0)`
was insufficient. The compiler's static analysis is aggressive enough
to flag the `memset(..., 0)` pattern before evaluating the conditional,
thus still triggering the error.
To resolve this robustly, this change introduces a `static inline`
helper function, `__kselftest_memset_safe()`. This function wraps the
size check and the `memset()` call. By replacing the direct `memset()`
in the `__TEST_F_IMPL` macro with a call to this helper, we create an
abstraction boundary. This prevents the compiler's static analyzer from
"seeing" the problematic pattern at the macro expansion site, resolving
the build failure.
Build Context:
Compiler: Android (14488419, +pgo, +bolt, +lto, +mlgo, based on r584948) clang version 22.0.0 (https://android.googlesource.com/toolchain/llvm-project 2d65e4108033380e6fe8e08b1f1826cd2bfb0c99)

drm/i915/gem: Zero-initialize the eb.vma array in i915_gem_do_execbuffer
Initialize the eb.vma array with values of 0 when the eb structure is
first set up. In particular, this sets the eb->vma[i].vma pointers to
NULL, simplifying cleanup and getting rid of the bug described below.
During the execution of eb_lookup_vmas(), the eb->vma array is
successively filled up with struct eb_vma objects. This process includes
calling eb_add_vma(), which might fail; however, even in the event of
failure, eb->vma[i].vma is set for the currently processed buffer.
If eb_add_vma() fails, eb_lookup_vmas() returns with an error, which
prompts a call to eb_release_vmas() to clean up the mess. Since
eb_lookup_vmas() might fail during processing any (possibly not first)
buffer, eb_release_vmas() checks whether a buffer's vma is NULL to know
at what point did the lookup function fail.
In eb_lookup_vmas(), eb->vma[i].vma is set to NULL if either the helper
function eb_lookup_vma() or eb_validate_vma() fails. eb->vma[i+1].vma is
set to NULL in case i915_gem_object_userptr_submit_init() fails; the
current one needs to be cleaned up by eb_release_vmas() at this point,
so the next one is set. If eb_add_vma() fails, neither the current nor
the next vma is set to NULL, which is a source of a NULL deref bug
described in the issue linked in the Closes tag.
When entering eb_lookup_vmas(), the vma pointers are set to the slab
poison value, instead of NULL. This doesn't matter for the actual
lookup, since it gets overwritten anyway, however the eb_release_vmas()
function only recognizes NULL as the stopping value, hence the pointers
are being set to NULL as they go in case of intermediate failure. This
patch changes the approach to filling them all with NULL at the start
instead, rather than handling that manually during failure.

blk-mq: skip CPU offline notify on unmapped hctx
If an hctx has no software ctx mapped, blk_mq_map_swqueue() never
allocates tags and leaves hctx->tags NULL. The CPU hotplug offline
notifier can still run for that hctx, return early since hctx cannot
hold any requests.

smb: client: fix UBSAN array-index-out-of-bounds in smb2_copychunk_range
struct copychunk_ioctl_req::ChunkCount is annotated with
__counted_by_le() as the number of elements in Chunks[].
smb2_copychunk_range reuses ChunkCount to store the number of chunks
sent in the current iteration. If a later iteration populates more
chunks than a previous one, the stale smaller value trips UBSAN.
Set ChunkCount to chunk_count (allocated capacity) before populating
Chunks[].

smb3 client: add missing tracepoint for unsupported ioctls
In debugging a recent problem with an xfstest, noticed that we weren't
tracing cases where the ioctl was not supported. Add dynamic tracepoint:
"trace-cmd record -e smb3_unsupported_ioctl"
and then after running an app which calls unsupported ioctl,
"trace-cmd show"would display e.g.
xfs_io-7289 [012] ..... 1205.137765: smb3_unsupported_ioctl: xid=19 fid=0x4535bb84 ioctl cmd=0x801c581f
