[PATCH] m68knommu: fix scheduling and race problems in idle loop
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.
