Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6

Pull crypto updates from Herbert Xu:
 "API:

   - Decryption test vectors are now automatically generated from
     encryption test vectors.

  Algorithms:

   - Fix unaligned access issues in crc32/crc32c.

   - Add zstd compression algorithm.

   - Add AEGIS.

   - Add MORUS.

  Drivers:

   - Add accelerated AEGIS/MORUS on x86.

   - Add accelerated SM4 on arm64.

   - Removed x86 assembly salsa implementation as it is slower than C.

   - Add authenc(hmac(sha*), cbc(aes)) support in inside-secure.

   - Add ctr(aes) support in crypto4xx.

   - Add hardware key support in ccree.

   - Add support for new Centaur CPU in via-rng"
