sched: Generic migrate_disable
Make migrate_disable() be a preempt_disable() for !rt kernels. This allows generic code to use it but still enforces that these code sections stay relatively small. A preemptible migrate_disable() accessible for general use would allow people growing arbitrary per-cpu crap instead of clean these things up.
