Merge branch 'linus' of 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 4.9:

  API:
   - The crypto engine code now supports hashes.

  Algorithms:
   - Allow keys >= 2048 bits in FIPS mode for RSA.

  Drivers:
   - Memory overwrite fix for vmx ghash.
   - Add support for building ARM sha1-neon in Thumb2 mode.
   - Reenable ARM ghash-ce code by adding import/export.
   - Reenable img-hash by adding import/export.
   - Add support for multiple cores in omap-aes.
   - Add little-endian support for sha1-powerpc.
   - Add Cavium HWRNG driver for ThunderX SoC"
