perf stat: Fix aggreate counter reading accounting
Introduced in: c52b12ed, when this sequence: count[0] = count[1] = count[2] = 0; Was replaced with: aggr->val = 0; Which is equivalent to zeroing just the first entry in the 'count' array. Fix it by zeroing the three entries with: aggr->val = aggr->ena = aggr->run = 0; Reported-by: Ingo Molnar <mingo@elte.hu> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Tom Zanussi <tzanussi@gmail.com> LKML-Reference: <new-submission> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
