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" * tag 'crc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: (36 commits) x86/crc: drop the avx10_256 functions and rename avx10_512 to avx512 lib/crc: remove unnecessary prompt for CONFIG_CRC64 lib/crc: remove unnecessary prompt for CONFIG_LIBCRC32C lib/crc: remove unnecessary prompt for CONFIG_CRC8 lib/crc: remove unnecessary prompt for CONFIG_CRC7 lib/crc: remove unnecessary prompt for CONFIG_CRC4 lib/crc7: unexport crc7_be_syndrome_table lib/crc_kunit.c: update comment in crc_benchmark() lib/crc_kunit.c: add test and benchmark for crc7_be() x86/crc32: optimize tail handling for crc32c short inputs riscv/crc64: add Zbc optimized CRC64 functions riscv/crc-t10dif: add Zbc optimized CRC-T10DIF function riscv/crc32: reimplement the CRC32 functions using new template riscv/crc: add "template" for Zbc optimized CRC functions x86/crc: add ANNOTATE_NOENDBR to suppress objtool warnings x86/crc32: improve crc32c_arch() code generation with clang x86/crc64: implement crc64_be and crc64_nvme using new template x86/crc-t10dif: implement crc_t10dif using new template x86/crc32: implement crc32_le using new template x86/crc: add "template" for [V]PCLMULQDQ based CRC functions ...
