Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto update from Herbert Xu: "Here is the crypto update for 4.1: New interfaces: - user-space interface for AEAD - user-space interface for RNG (i.e., pseudo RNG) New hashes: - ARMv8 SHA1/256 - ARMv8 AES - ARMv8 GHASH - ARM assembler and NEON SHA256 - MIPS OCTEON SHA1/256/512 - MIPS img-hash SHA1/256 and MD5 - Power 8 VMX AES/CBC/CTR/GHASH - PPC assembler AES, SHA1/256 and MD5 - Broadcom IPROC RNG driver Cleanups/fixes: - prevent internal helper algos from being exposed to user-space - merge common code from assembly/C SHA implementations - misc fixes" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (169 commits) crypto: arm - workaround for building with old binutils crypto: arm/sha256 - avoid sha256 code on ARMv7-M crypto: x86/sha512_ssse3 - move SHA-384/512 SSSE3 implementation to base layer crypto: x86/sha256_ssse3 - move SHA-224/256 SSSE3 implementation to base layer crypto: x86/sha1_ssse3 - move SHA-1 SSSE3 implementation to base layer crypto: arm64/sha2-ce - move SHA-224/256 ARMv8 implementation to base layer crypto: arm64/sha1-ce - move SHA-1 ARMv8 implementation to base layer crypto: arm/sha2-ce - move SHA-224/256 ARMv8 implementation to base layer crypto: arm/sha256 - move SHA-224/256 ASM/NEON implementation to base layer crypto: arm/sha1-ce - move SHA-1 ARMv8 implementation to base layer crypto: arm/sha1_neon - move SHA-1 NEON implementation to base layer crypto: arm/sha1 - move SHA-1 ARM asm implementation to base layer crypto: sha512-generic - move to generic glue implementation crypto: sha256-generic - move to generic glue implementation crypto: sha1-generic - move to generic glue implementation crypto: sha512 - implement base layer for SHA-512 crypto: sha256 - implement base layer for SHA-256 crypto: sha1 - implement base layer for SHA-1 crypto: api - remove instance when test failed crypto: api - Move alg ref count init to crypto_check_alg ...
