[v4,47/48] perf stat: Correct first_shadow_cpu to return index

Commit Message

Ian Rogers Jan. 5, 2022, 6:13 a.m. UTC

perf_stat__update_shadow_stats and perf_stat__print_shadow_stats use a
cpu map index rather than a CPU, but first_shadow_cpu is returning the
wrong value for this. Change first_shadow_cpu to
first_shadow_cpu_map_idx to make things agree.
