Hi Steffen,

I found cpu_active usage in crypto/pcrypt.c and was wondering what
that's doing there. I would really like to contain that thing to as
narrow a piece of kernel as I possible can (sched/cpuset/hotplug) but it
appears to be spreading.

Also, wth is all this kernel/padata.c stuff? There's next to no useful
comment in there and the only consumer seems to be pcrypt, does that
really need to be in kernel/ ?
