Re-work the m68knommu specific idle code according to suggestions from Nick Piggin <nickpiggin@yahoo.com.au>. A couple of rules that we need to follow: 1. Preempt should now disabled over idle routines. Should only be enabled to call schedule() then disabled again. 3. When cpu_idle finds (need_resched() == 'true'), it should call schedule(). It should not call schedule() otherwise. Also fix interrupt locking around the need_resched() and cpu stop state so that there is no race condition.
