Subject: sched/preempt, powerpc, kvm: Use need_resched() instead of should_resched()

From: Konstantin Khlebnikov <[email protected]>

commit c56dadf39761a6157239cac39e3988998c994f98 upstream.

Function should_resched() is equal to (!preempt_count() && need_resched()). In preemptive kernel preempt_count here is non-zero because of vc->lock.
