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

Pull crypto update from Herbert Xu:
 - Optimised AES/SHA1 for ARM.
 - IPsec ESN support in talitos and caam.
 - x86_64/avx implementation of cast5/cast6.
 - Add/use multi-algorithm registration helpers where possible.
 - Added IBM Power7+ in-Nest support.
 - Misc fixes.

Fix up trivial conflicts in crypto/Kconfig due to the sparc64 crypto
config options being added next to the new ARM ones.

[ Side note: cut-and-paste duplicate help texts make those conflicts
  harder to read than necessary, thanks to git being smart about
  minimizing conflicts and maximizing the common parts... ]
