Subject: [PATCH v4 13/48] perf cpumap: Simplify equal function name.
Rename cpu_map__compare_aggr_cpu_id to aggr_cpu_id__equal, the cpu_map
part of the name is misleading. Equal better describes the function than
compare.
Switch to const pointer rather than value as struct given the number of
variables in aggr_cpu_id.
