[PATCH 1/2] perf tools: Honour the cpu list parameter when also monitoring a thread list

From: Arnaldo Carvalho de Melo
Date: Sun May 15 2011 - 12:38:54 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

The perf_evlist__create_maps was discarding the --cpu parameter when a
--pid or --tid was specified, fix that.
