Merge tag 'crc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux

Pull CRC updates from Eric Biggers:

 - Several improvements related to crc_kunit, to align with the standard
   KUnit conventions and make it easier for developers and CI systems to
   run this test suite

 - Add an arm64-optimized implementation of CRC64-NVME

 - Remove unused code for big endian arm64
