Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu:
"This fixes the following issues:
- Fix AVX detection to prevent use of non-existent AESNI.
- Some SPARC ciphers did not set their IV size which may lead to
memory corruption"
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: ahash - ensure statesize is non-zero
crypto: camellia_aesni_avx - Fix CPU feature checks
crypto: sparc - initialize blkcipher.ivsize
