This series is targeting libcrypto-next and can also be retrieved from:

This series introduces a library API for MD5 and HMAC-MD5 and
reimplements the crypto_shash "md5" and "hmac(md5)" on top of it.

The library API will also be usable directly by various in-kernel users
that are stuck with MD5 due to having to implement legacy protocols.

This should again look quite boring and familiar, as it mirrors the
SHA-1 and SHA-2 changes closely.

Changed in v2:
  - Kept the architecture-optimized MD5 code, since unfortunately there
    were objections to removing it.

Eric Biggers (7):
  lib/crypto: md5: Add MD5 and HMAC-MD5 library functions
  lib/crypto: mips/md5: Migrate optimized code into library
  mips: cavium-octeon: Move octeon-crypto.c into parent dir
  lib/crypto: powerpc/md5: Migrate optimized code into library
  lib/crypto: sparc/md5: Migrate optimized code into library
  crypto: md5 - Wrap library and add HMAC support
  lib/crypto: tests: Add KUnit tests for MD5 and HMAC-MD5

Applied to https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git/log/?h=libcrypto-next

Reviews and acks still greatly appreciated, of course!
