[v2,13/48] perf cpumap: Simplify equal function name.

Commit Message

Ian Rogers Dec. 23, 2021, 7:45 a.m. UTC

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.
