Pull crypto fixes from Herbert Xu:
 "This fixes three issues:

   - if ccp is loaded on a machine without ccp, it will incorrectly
     activate causing all requests to fail.  Fixed by preventing ccp
     from loading if hardware isn't available.

   - not all IRQs were enabled for the qat driver, leading to potential
     stalls when it is used

   - disabled buggy AVX CTR implementation in aesni"

* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: aesni - disable "by8" AVX CTR optimization
  crypto: ccp - Check for CCP before registering crypto algs
  crypto: qat - Enable all 32 IRQs
