Pull crypto fixes from Herbert Xu:
 - Fix for CPU hotplug hang in padata.
 - Avoid using cpu_active inappropriately in pcrypt and padata.
 - Fix for user-space algorithm lookup hang with IV generators.
 - Fix for netlink dump of algorithms where stuff went missing due to
   incorrect calculation of message size.

* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: user - Fix size of netlink dump message
