Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu:
"This fixes a build problem with sha-mb with old toolchains and an
implementation bug in the ctr(aes)/by8 branch of aesni-intel that's
enabled when AVX is available"
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: sha-mb - Add avx2_supported check.
crypto: aesni - fix "by8" variant for 128 bit keys
