[PATCH 21/54] perf annotate: Pass evsel instead of evidx on annotation functions

From: Arnaldo Carvalho de Melo
Date: Mon Mar 18 2013 - 12:33:12 EST

From: Namhyung Kim <namhyung.kim@xxxxxxx>

Pass evsel instead of evidx. This is a preparation for supporting event
group view in annotation and no functional change is intended.
