perf evlist: Add has_user_cpus member
Subsequent patches will need to call perf_evlist__propagate_maps without reference to a "target". Add evlist->has_user_cpus to record whether the user has specified which cpus to target (and therefore whether that list of cpus should override the default settings for a selected event i.e. the cpu maps should be propagated) Signed-off-by: NAdrian Hunter <adrian.hunter@intel.com> Acked-by: NJiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@intel.com> Link: http://lkml.kernel.org/r/1441699142-18905-5-git-send-email-adrian.hunter@intel.comSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>
