Updates for the kernel's CRC (cyclic redundancy check) code:
- Reorganize the architecture-optimized CRC code. It now lives in
lib/crc/$(SRCARCH)/ rather than arch/$(SRCARCH)/lib/, and it is no
longer artificially split into separate generic and arch modules.
This allows better inlining and dead code elimination. The generic
CRC code is also no longer exported, simplifying the API. (This
mirrors the similar changes to SHA-1 and SHA-2 in lib/crypto/,
which can be found in the "Crypto library updates" pull request.)
- Improve crc32c() performance on newer x86_64 CPUs on long messages
by enabling the VPCLMULQDQ optimized code.
- Simplify the crypto_shash wrappers for crc32_le() and crc32c().
Register just one shash algorithm for each that uses the (fully
optimized) library functions, instead of unnecessarily providing
direct access to the generic CRC code.
- Remove unused and obsolete drivers for hardware CRC engines.
- Remove CRC-32 combination functions that are no longer used.
- Add kerneldoc for crc32_le(), crc32_be(), and crc32c().
- Convert the crc32() macro to an inline function.
