[PATCH RFC 0/2] kvm: Better yield_to candidate using preemption notifiers

2013-03-04 Thread Raghavendra K T
This patch series further filters better vcpu candidate to yield to in PLE handler. The main idea is to record the preempted vcpus using preempt notifiers and iterate only those preempted vcpus in the handler. Note that the vcpus which were in spinloop during pause loop exit are already filtered.
