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"
