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. ]

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (174 commits)
  crypto: s5p - add AES support for Exynos5433

  crypto: s5p - update iv after AES-CBC op end
  crypto: x86/poly1305 - Clear key material from stack in SSE2 variant
  crypto: caam - generate hash keys in-place
  crypto: caam - fix DMA mapping xcbc key twice
  crypto: caam - fix hash context DMA unmap size
  hwrng: bcm2835 - fix probe as platform device
  crypto: s5p-sss - Use AES_BLOCK_SIZE define instead of number
  crypto: stm32 - drop pointless static qualifier in stm32_hash_remove()
  crypto: chelsio - Fixed Traffic Stall
  crypto: marvell - Remove set but not used variable 'ivsize'
  crypto: ccp - Update driver messages to remove some confusion
  crypto: adiantum - add 1536 and 4096-byte test vectors
  crypto: nhpoly1305 - add a test vector with len % 16 != 0
  crypto: arm/aes-ce - update IV after partial final CTR block
