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

Pull crypto fixes from Herbert Xu:
 "Fix a bug in the ARM XTS implementation that can cause failures in
  decrypting encrypted disks, and fix is a memory overwrite bug that can
  cause a crash which can be triggered from userspace"

* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: aesni - fix memory usage in GCM decryption
  crypto: arm/aes update NEON AES module to latest OpenSSL version
