Except that it's done a little indirectly, via initializing the idle
vcpu, rather than calling something like sched_init_pcpu() when the
cpu is brought up before creating an idle vcpu for it. :-)  Anyway,
maybe once I get the credit2 stuff working again, I may think about
writing a patch to clean it up a bit... mostly so that it's easier to
follow what's going on.
