Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6

Pull crypto updates from Herbert Xu:
 "API:

   - Delay boot-up self-test for built-in algorithms

  Algorithms:

   - Remove fallback path on arm64 as SIMD now runs with softirq off

  Drivers:

   - Add Keem Bay OCS ECC Driver"
