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"
