Merge tag 'locking-core-2026-02-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull locking updates from Ingo Molnar:
"Lock debugging:

- Implement compiler-driven static analysis locking context checking,
using the upcoming Clang 22 compiler's context analysis features
(Marco Elver)

We removed Sparse context analysis support, because prior to
removal even a defconfig kernel produced 1,700+ context tracking
Sparse warnings, the overwhelming majority of which are false
positives. On an allmodconfig kernel the number of false positive
context tracking Sparse warnings grows to over 5,200... On the plus
side of the balance actual locking bugs found by Sparse context
analysis is also rather ... sparse: I found only 3 such commits in
the last 3 years. So the rate of false positives and the
maintenance overhead is rather high and there appears to be no
active policy in place to achieve a zero-warnings baseline to move
the annotations & fixers to developers who introduce new code.

Clang context analysis is more complete and more aggressive in
trying to find bugs, at least in principle. Plus it has a different
model to enabling it: it's enabled subsystem by subsystem, which
results in zero warnings on all relevant kernel builds (as far as
our testing managed to cover it). Which allowed us to enable it by
default, similar to other compiler warnings, with the expectation
that there are no warnings going forward. This enforces a
zero-warnings baseline on clang-22+ builds (Which are still limited
in distribution, admittedly)

Hopefully the Clang approach can lead to a more maintainable
zero-warnings status quo and policy, with more and more subsystems
and drivers enabling the feature. Context tracking can be enabled
for all kernel code via WARN_CONTEXT_ANALYSIS_ALL=y (default
disabled), but this will generate a lot of false positives.

( Having said that, Sparse support could still be added back,
if anyone is interested - the removal patch is still
relatively straightforward to revert at this stage. )

Rust integration updates: (Alice Ryhl, Fujita Tomonori, Boqun Feng)

- Add support for Atomic<i8/i16/bool> and replace most Rust native
AtomicBool usages with Atomic<bool>

- Clean up LockClassKey and improve its documentation

- Add missing Send and Sync trait implementation for SetOnce

- Make ARef Unpin as it is supposed to be

- Add __rust_helper to a few Rust helpers as a preparation for
helper LTO

- Inline various lock related functions to avoid additional function
calls

WW mutexes:

- Extend ww_mutex tests and other test-ww_mutex updates (John
Stultz)

Misc fixes and cleanups:

- rcu: Mark lockdep_assert_rcu_helper() __always_inline (Arnd
Bergmann)

- locking/local_lock: Include more missing headers (Peter Zijlstra)

- seqlock: fix scoped_seqlock_read kernel-doc (Randy Dunlap)

lib/tests: convert test_min_heap module to KUnit

Move lib/test_min_heap.c to lib/tests/min_heap_kunit.c and convert it to
use KUnit.

This change switches the ad-hoc test code to standard KUnit test cases.
The test data remains the same, but the verification logic is updated to
use KUNIT_EXPECT_* macros.

Also remove CONFIG_TEST_MIN_HEAP from arch/*/configs/* because it is no
longer used. The new CONFIG_MIN_HEAP_KUNIT_TEST will be automatically
enabled by CONFIG_KUNIT_ALL_TESTS.

The reasons for converting to KUnit are:

1. Standardization:
Switching from ad-hoc printk-based reporting to the standard
KTAP format makes it easier for CI systems to parse and report test
results

2. Better Diagnostics:
Using KUNIT_EXPECT_* macros automatically provides detailed
diagnostics on failure.

3. Tooling Integration:
It allows the test to be managed and executed using standard
KUnit tools.

lib: Support ARCH_HAS_CPU_CACHE_INVALIDATE_MEMREGION

ARCH_HAS_CPU_CACHE_INVALIDATE_MEMREGION provides the mechanism for
invalidating certain memory regions in a cache-incoherent manner. Currently
this is used by NVDIMM and CXL memory drivers in cases where it is
necessary to flush all data from caches by physical address range.
The operations in question are effectively memory hotplug, where stale
data might otherwise remain in the caches.

This is separate from the invalidates done to enable use of non-coherent
DMA masters, primarily in terms of when it is needed (not related to DMA
mappings) and how deep the flush must push data. The flushes done for
non-coherent DMA only need to reach the Point of Coherence of a single host
(which is often nearer CPUs and DMA masters than the physical storage).
This operation must push the data out of non architectural caches
(memory-side caches, write buffers etc) and typically all the way to the
memory device.

In some architectures these operations are supported by system components
that may become available only later in boot as they are either present
on a discoverable bus, or via a firmware description of an MMIO interface
(e.g. ACPI DSDT). Provide a framework to handle this case.

Architectures can opt in for this support via
CONFIG_GENERIC_CPU_CACHE_MAINTENANCE

Add a registration framework. Each driver provides an ops structure and
the first op is Write Back and Invalidate by PA Range. The driver may
over invalidate.

For systems that can perform this operation asynchronously an optional
completion check operation is also provided. If present that must be called
to ensure that the action has finished. This provides a considerable
performance advantage if multiple agents are involved in the maintenance
operation.

When multiple agents are present in the system each should register with
this framework and the core code will issue the invalidate to all of them
before checking for completion on each. This is done to avoid need for
filtering in the core code which can become complex when interleave,
potentially across different cache coherency hardware is going on, so it
is easier to tell everyone and let those who don't care do nothing.
