[PATCH v4 0/6] Make evlist CPUs more accurate

[Ian Rogers]

Based on the thread:
https://lore.kernel.org/linux-perf-users/CAP-5=fVMHzTfKdpWMXtbtx7t14u2f4WzNak+F0Q93cQ7CZfhbg@xxxxxxxxxxxxxx/

First patch is a cherry-pick to avoid a conflict of:
https://lore.kernel.org/linux-perf-users/20220414014642.3308206-2-irogers@xxxxxxxxxx/
Second patch makes all_cpus more accurate when there are command line CPUs.
The third patch fixes perf stat metric-only output for uncore metrics.
The fourth patch makes cleans up merging of dummy CPU maps.
The fifth and sixth patch try to make user_requested_cpus and all_cpus
clearer with documentation and by renaming all_cpus.

The code no longer needs to add an intersect function and so the API
is removed and the merged API left unchangaged.

Ian Rogers (6):
  perf cpumap: Switch to using perf_cpu_map API
  perf evlist: Clear all_cpus before propagating
  perf stat: Avoid printing cpus with no counters
  perf cpumap: Handle dummy maps as empty in subset
  perf evlist: Add to user_requested_cpus documentation
  perf evlist: Rename all_cpus
