This module registers a crc32 algorithm and a crc32c algorithm that use the optional CRC32 and CRC32C instructions in ARMv8. Tested on AMD Seattle. Improvement compared to crc32c-generic algorithm: TCRYPT CRC32C speed test shows ~450% speedup. Simple dd write tests to btrfs filesystem show ~30% speedup.
