[PATCH 2/5] perf_events: generalize use of event_filter_match() (v6)

From: Stephane Eranian
Date: Tue Nov 30 2010 - 13:22:11 EST


Replace all occurrences of:
event->cpu != -1 && event->cpu == smp_processor_id()
by a call to:
event_filter_match(event)

This makes the code more consistent and will make the cgroup
patch smaller.
