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"
