Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6

Pull crypto fixes from Herbert Xu:
 "This removes IPsec ESN support from the talitos/caam drivers since
  they were implemented incorrectly, causing interoperability problems
  if ESN is used with them."

* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  Revert "crypto: caam - add IPsec ESN support"
  Revert "crypto: talitos - add IPsec ESN support"
