Subject[PATCH] perf target: Move what map fucntion to call check into function.
Date
Check for cpu_map__dummy_new() or cpu_map__new() to be called in
perf_evlist__create_maps() is more complicated. This patch moves
the checking work into target.h, combining two conditions and making
perf_evlist__create_maps() more readable.
