[PATCH 0/5] perf_counts clean up and perf stat report bug fix

[Ian Rogers]

perf_counts takes a CPU map index as an argument, however, there were
a few places where this hadn't been cleaned up and the index was
called cpu. In part this led to the bug discovered by Michael Petlan in:
https://lore.kernel.org/linux-perf-users/CAP-5=fWQR=sCuiSMktvUtcbOLidEpUJLCybVF6=BRvORcDOq+g@xxxxxxxxxxxxxx/

Fix the bug, tidy up more of the arguments passed to perf_counts, add
a test to ensure the bug isn't reintroduced and add a helper macro to
iterate over just CPU map indices.

Ian Rogers (5):
  perf stat: Fix and validate inputs in stat events
  perf stat: Add stat record+report test
  perf cpumap: Add perf_cpu_map__for_each_idx
  perf bpf_counter: Tidy use of CPU map index
  perf stat: Make use of index clearer with perf_counts
