perf stat: Fix per-socket output bug for uncore events
This patch fixes a problem reported by Andi Kleen on perf stat when measuring uncore events: # perf stat --per-socket -e uncore_pcu/event=0x0/ -I1000 -a sleep 2 It would not report counts for the second socket. That was due to a cpu mapping bug in print_aggr(). This patch also fixes the socket numbering bug for <not counted> events.
