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

Pull crypto fixes from Herbert Xu:
 "This fixes the following issues:
   - Zero-length DMA mapping in caam
   - Invalidly mapping stack memory for DMA in talitos
   - Use after free in cavium/nitrox
   - Key parsing in authenc
   - Undefined shift in sm3
   - Bogus completion call in authencesn
   - SHA support detection in caam"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: sm3 - fix undefined shift by >= width of value
  crypto: talitos - fix ablkcipher for CONFIG_VMAP_STACK
  crypto: talitos - reorder code in talitos_edesc_alloc()
  crypto: adiantum - initialize crypto_spawn::inst
  crypto: cavium/nitrox - Use after free in process_response_list()
  crypto: authencesn - Avoid twice completion call in decrypt path
  crypto: caam - fix SHA support detection
  crypto: caam - fix zero-length buffer DMA mapping
  crypto: ccree - convert to use crypto_authenc_extractkeys()
  crypto: bcm - convert to use crypto_authenc_extractkeys()
  crypto: authenc - fix parsing key with misaligned rta_len
