Based on the thread: https://lore.kernel.org/linux-perf-users/CAP-5=fVMHzTfKdpWMXtbtx7t14u2f4WzNak+F0Q93cQ7CZfhbg@mail.gmail.com/
First patch is a cherry-pick to avoid a conflict of: https://lore.kernel.org/linux-perf-users/20220414014642.3308206-2-irogers@google.com/ 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
