Register a cpu hotplug notifier which reinitializes the scheduler
domains hierarchy. The notifier temporarily attaches all running cpus
to a "dummy" domain (like we currently do during boot) to avoid
balancing. It then calls arch_init_sched_domains which rebuilds the
"real" domains and reattaches the cpus to them.
Also change __init attributes to __devinit where necessary.

Thanks Nathan, this looks great.
I think the next step is to now make the setup code only use cpu_online_map
and get rid of everywhere I had been doing cpus_and(tmp, ...,
cpu_online_map).
This may also make your patch 1/2 unnecessary? What do you think?
