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

Pull crypto update from Herbert Xu:
 "Here is the crypto update for 3.9:

   - Added accelerated implementation of crc32 using pclmulqdq.

   - Added test vector for fcrypt.

   - Added support for OMAP4/AM33XX cipher and hash.

   - Fixed loose crypto_user input checks.

   - Misc fixes"
