SubjectRe: [PATCH] sched: CPU hotplug events must not destroy scheduler domains created by the cpusets

Paul, I just realized that this won't work. We actually need the default
version of arch_init_sched_domains() which builds the default domain. It's
used during bootup. It's only the hotplug event handling where we do not want
the default.
I could still redo the switch() statement as you suggested but it seems that
it's not going to improve the readability that much at this point.
