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)
