perf stat: Define MATCH_EVENT for easy attr checking
MATCH_EVENT is useful: 1. for multiple attrs checking 2. avoid repetition of PERF_TYPE_ and PERF_COUNT_ and save space 3. avoids line breakage Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Cc: Peter Zijlstra <peterz@infradead.org> LKML-Reference: <1246440909.3403.5.camel@hpdv5.satnam> Signed-off-by: Ingo Molnar <mingo@elte.hu>
