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

Pull crypto fixes from Herbert Xu:
 "This fixes the following issues:

   - The selftest overreads the IV test vector.

  - Fix potential infinite loop in sunxi-ss driver.

   - Fix powerpc build failure when VMX is set without VSX"

* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: testmgr - don't copy from source IV too much
  crypto: sunxi-ss - Fix a possible driver hang with ciphers
  crypto: vmx - VMX crypto should depend on CONFIG_VSX
