Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull ARM AES crypto fixes from Herbert Xu:
"This push fixes a regression on ARM where odd-sized blocks supplied to
AES may cause crashes"
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: arm-aes - fix encryption of unaligned data
crypto: arm64-aes - fix encryption of unaligned data
