raid6: turn the userspace test harness into a kunit test

Patch series "cleanup the RAID6 P/Q library", v3.

This series cleans up the RAID6 P/Q library to match the recent updates to
the RAID 5 XOR library and other CRC/crypto libraries. This includes
providing properly documented external interfaces, hiding the internals,
using static_call instead of indirect calls and turning the user space
test suite into an in-kernel kunit test which is also extended to improve
coverage.

Note that this changes registration so that non-priority algorithms are
not registered, which greatly helps with the benchmark time at boot time.
I'd like to encourage all architecture maintainers to see if they can
further optimized this by registering as few as possible algorithms when
there is a clear benefit in optimized or more unrolled implementations.


This patch (of 18):

Currently the raid6 code can be compiled as userspace code to run the test
suite. Convert that to be a kunit case with minimal changes to avoid
mutating global state so that we can drop this requirement.

Note that this is not a good kunit test case yet and will need a lot more
work, but that is deferred until the raid6 code is moved to it's new
place, which is easier if the userspace makefile doesn't need adjustments
for the new location first.

lib/bitrev: Introduce GENERIC_BITREVERSE

The generic bit reversal implementation is controlled by
!HAVE_ARCH_BITREVERSE. This makes it difficult for architectures to
provide a hardware-accelerated implementation while being able to
fall back to the generic version if needed.

This patch adds GENERIC_BITREVERSE, so bitreverse API is controlled by
BITREVERSE, GENERIC_BITREVERSE and HAVE_ARCH_BITREVERSE options. The
relationship between them is described as follows:

- BITREVERSE is selected by user code; it's required to generate the API;
- Architectures may select HAVE_ARCH_BITREVERSE and provide an arch
implementation in arch/$(ARCH)/include/asm/bitrev.h.
- if HAVE_ARCH_BITREVERSE isn't set, BITREVERSE selects GENERIC_BITREVERSE;
- if GENERIC_BITREVERSE is set and HAVE_ARCH_BITREVERSE is not, the kernel
provides generic implementation only, and wires bitrevXX() to it.
- if HAVE_ARCH_BITREVERSE is set and GENERIC_BITREVERSE is not, the arch
code provides __arch_bitrevXX(), and it is wired to bitrevXX();
- if both GENERIC_BITREVERSE and HAVE_ARCH_BITREVERSE are selected, the kernel
generates generic___bitrev(), but wires bitrev() to the __arch_bitrev().

The last option allows architectures to use generic___bitrev() as a
fallback option.

Drivers and core code should never select GENERIC_BITREVERSE or
HAVE_ARCH_BITREVERSE explicitly.

Architectures that require generic bitreverse API as a fallback should
explicitly enable GENERIC_BITREVERSE together with HAVE_ARCH_BITREVERSE.

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.
