Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto update from Herbert Xu:
- The crypto API is now documented :)
- Disallow arbitrary module loading through crypto API.
- Allow get request with empty driver name through crypto_user.
- Allow speed testing of arbitrary hash functions.
- Add caam support for ctr(aes), gcm(aes) and their derivatives.
- nx now supports concurrent hashing properly.
- Add sahara support for SHA1/256.
- Add ARM64 version of CRC32.
- Misc fixes.
