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" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (112 commits) crypto: chtls - free beyond end rspq_skb_cache crypto: chtls - kbuild warnings crypto: chtls - dereference null variable crypto: chtls - wait for memory sendmsg, sendpage crypto: chtls - key len correction crypto: salsa20 - Revert "crypto: salsa20 - export generic helpers" crypto: x86/salsa20 - remove x86 salsa20 implementations crypto: ccp - Add GET_ID SEV command crypto: ccp - Add DOWNLOAD_FIRMWARE SEV command crypto: qat - Add MODULE_FIRMWARE for all qat drivers crypto: ccree - silence debug prints crypto: ccree - better clock handling crypto: ccree - correct host regs offset crypto: chelsio - Remove separate buffer used for DMA map B0 block in CCM crypt: chelsio - Send IV as Immediate for cipher algo crypto: chelsio - Return -ENOSPC for transient busy indication. crypto: caam/qi - fix warning in init_cgr() crypto: caam - fix rfc4543 descriptors crypto: caam - fix MC firmware detection crypto: clarify licensing of OpenSSL asm code ...
