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

Pull crypto fixes from Herbert Xu:
 "This push fixes a build error on 32-bit archs in the hifn driver as
  well as a potential deadlock in the caam driver."

* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: caam - fix possible deadlock condition
  crypto: hifn_795x - fix 64bit division and undefined __divdi3 on 32bit archs
