Subject: [PATCH v2 2/3] KVM: PPC: Book3S HV: Use need_resched() instead of should_resched()

From: Konstantin Khlebnikov <[email-masked]>
Date: Wed, 15 Jul 2015 12:52:03 +0300

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