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 a regression in the cryptd code that breaks certain
  accelerated AED algorithms as well as an older regression in the
  caam driver that breaks IPsec"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: caam - fix IV loading for authenc (giv)decryption
  crypto: cryptd - Use correct tfm object for AEAD tracking
