Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6

Pull crypto update from Herbert Xu:
 "API:
   - Add helper for simple skcipher modes.
   - Add helper to register multiple templates.
   - Set CRYPTO_TFM_NEED_KEY when setkey fails.
   - Require neither or both of export/import in shash.
   - AEAD decryption test vectors are now generated from encryption
     ones.
   - New option CONFIG_CRYPTO_MANAGER_EXTRA_TESTS that includes random
     fuzzing.

  Algorithms:
   - Conversions to skcipher and helper for many templates.
   - Add more test vectors for nhpoly1305 and adiantum.

  Drivers:
   - Add crypto4xx prng support.
   - Add xcbc/cmac/ecb support in caam.
   - Add AES support for Exynos5433 in s5p.
   - Remove sha384/sha512 from artpec7 as hardware cannot do partial
     hash"

[ There is a merge of the Freescale SoC tree in order to pull in changes
  required by patches to the caam/qi2 driver. ]
