Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto updates from Herbert Xu:
"Here is the crypto update for 3.15:
- Added 3DES driver for OMAP4/AM43xx
- Added AVX2 acceleration for SHA
- Added hash-only AEAD algorithms in caam
- Removed tegra driver as it is not functioning and the hardware is
too slow
- Allow blkcipher walks over AEAD (needed for ARM)
- Fixed unprotected FPU/SSE access in ghash-clmulni-intel
- Fixed highmem crash in omap-sham
- Add (zero entropy) randomness when initialising hardware RNGs
- Fixed unaligned ahash comletion functions
- Added soft module depedency for crc32c for initrds that use crc32c"
