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" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (60 commits) crypto: ghash-clmulni-intel - use C implementation for setkey() crypto: x86/sha1 - reduce size of the AVX2 asm implementation crypto: x86/sha1 - fix stack alignment of AVX2 variant crypto: x86/sha1 - re-enable the AVX variant crypto: sha - SHA1 transform x86_64 AVX2 crypto: crypto_wq - Fix late crypto work queue initialization crypto: caam - add missing key_dma unmap crypto: caam - add support for aead null encryption crypto: testmgr - add aead null encryption test vectors crypto: export NULL algorithms defines crypto: caam - remove error propagation handling crypto: hash - Simplify the ahash_finup implementation crypto: hash - Pull out the functions to save/restore request crypto: hash - Fix the pointer voodoo in unaligned ahash crypto: caam - Fix first parameter to caam_init_rng crypto: omap-sham - Map SG pages if they are HIGHMEM before accessing crypto: caam - Dynamic memory allocation for caam_rng_ctx object crypto: allow blkcipher walks over AEAD data crypto: remove direct blkcipher_walk dependency on transform hwrng: add randomness to system from rng sources ...
