Christoph Hellwig 10dab13117 raid6/kunit: add a benchmark 
Add a benchmark to test the RAID 6 P/Q functions for more representative
block sizes and numbers of disks.  This splits the maximum alloc size used
for the benchmark from the max size for the kunit test because recovery is
currently limited to a single page at a time.  Hopefully this will be
fixed soon.

The runtime numbers are reported in GB/s as the numbers of modern
implementations are basically unreadable as MB/s.  This means
retro-architectures could report 0, but that is an easy tradeoff.

Christoph Hellwig 874d2edd07 xor/kunit: add a benchmark 
Add a benchmark to test the XOR functions for more representative block
sizes and numbers of disks.  Including 64k would be useful here, but
increasing the test buffer size increases the runtime of the functional
kunit test too much unfortunately.

The runtime numbers are reported in GB/s as the numbers of modern
implementations are basically unreadable as MB/s.  This means
retro-architectures could report 0, but that is an easy tradeoff.

Christoph Hellwig adfcf6e89b raid6: rework registration of optimized algorithms 
Replace the static array of algorithms with a call to an architecture
helper to register algorithms.  This serves two purposes: it avoid having
to register all algorithms in a single central place, and it removes the
need for the priority field by just registering the algorithms that the
architecture considers suitable for the currently running CPUs.

Christoph Hellwig 3626738bc7 raid6: move to lib/raid/ 
Move the raid6 code to live in lib/raid/ with the XOR code, and change the
internal organization so that each architecture has a subdirectory similar
to the CRC, crypto and XOR libraries, and fix up the Makefile to only
build files actually needed.

Also move the kunit test case from the history test/ subdirectory to
tests/ and use the normal naming scheme for it.

Christoph Hellwig e20043b476 xor: make xor.ko self-contained in lib/raid/ 
Move the asm/xor.h headers to lib/raid/xor/$(SRCARCH)/xor_arch.h and
include/linux/raid/xor_impl.h to lib/raid/xor/xor_impl.h so that the
xor.ko module implementation is self-contained in lib/raid/.

As this remove the asm-generic mechanism a new kconfig symbol is added to
indicate that a architecture-specific implementations exists, and
xor_arch.h should be included.
