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 4.15:

  API:

   - Disambiguate EBUSY when queueing crypto request by adding ENOSPC.
     This change touches code outside the crypto API.
   - Reset settings when empty string is written to rng_current.

  Algorithms:

   - Add OSCCA SM3 secure hash.

  Drivers:

   - Remove old mv_cesa driver (replaced by marvell/cesa).
   - Enable rfc3686/ecb/cfb/ofb AES in crypto4xx.
   - Add ccm/gcm AES in crypto4xx.
   - Add support for BCM7278 in iproc-rng200.
   - Add hash support on Exynos in s5p-sss.
   - Fix fallback-induced error in vmx.
   - Fix output IV in atmel-aes.
   - Fix empty GCM hash in mediatek.

  Others:

   - Fix DoS potential in lib/mpi.
   - Fix potential out-of-order issues with padata"
