sched: turn off PREEMPT_RESTRICT
PREEMPT_RESTRICT was a method aimed at reducing the amount of wakeup related preemption. It has a disadvantage though, it can prevent legitimate wakeups if a task is 'unlucky' to be hit too early by a tick that clears peer_preempt. Now that the wakeup preemption has been cleaned up we dont seem to have excessive preemptions anymore, so this feature can be turned off. (and removed in the next patch) Signed-off-by: Ingo Molnar <mingo@elte.hu>
