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"
