Linus Torvalds a578dd095d CRC updates for 6.17 ... 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. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCaIZ8rRQcZWJpZ2dlcnNA a2VybmVsLm9yZwAKCRDzXCl4vpKOK3yOAP9OuoCirD42ZHNSgQeGTzhhZ2jCHiPN BPvHChwtE2MSRwEA0ddNX36aOiEKmpjog3TMllOIBz7wBrwZV7KgoX75+AU= =uAY8 -----END PGP SIGNATURE----- Merge tag 'crc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux Pull CRC updates from Eric Biggers: - 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.
