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... ]
