Subject: [PATCH 03/18] perf evlist: Use bool instead of target argument in propagate_maps()

From: Jiri Olsa <jolsa@...nel.org>

We need only bool info wether user defined her own set of cpus.

Switching target argument to bool so it could be used from places
without target object defined in following patches.
