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

Pull CRC updates from Eric Biggers:
 "Another set of improvements to the kernel's CRC (cyclic redundancy
  check) code:

   - Rework the CRC64 library functions to be directly optimized, like
     what I did last cycle for the CRC32 and CRC-T10DIF library
     functions

   - Rewrite the x86 PCLMULQDQ-optimized CRC code, and add VPCLMULQDQ
     support and acceleration for crc64_be and crc64_nvme

   - Rewrite the riscv Zbc-optimized CRC code, and add acceleration for
     crc_t10dif, crc64_be, and crc64_nvme

   - Remove crc_t10dif and crc64_rocksoft from the crypto API, since
     they are no longer needed there

   - Rename crc64_rocksoft to crc64_nvme, as the old name was incorrect

   - Add kunit test cases for crc64_nvme and crc7

   - Eliminate redundant functions for calculating the Castagnoli CRC32,
     settling on just crc32c()

   - Remove unnecessary prompts from some of the CRC kconfig options

   - Further optimize the x86 crc32c code"
