    * Ensure empty cpumap is NULL from alloc
    * Rename perf_cpu_map__empty() to perf_cpu_map__has_any_cpu_or_is_empty()
    * Rename perf_cpu_map__default_new() to perf_cpu_map__new_online_cpus() and prefer sysfs
    * Rename perf_cpu_map__dummy_new() to perf_cpu_map__new_any_cpu()
  * perf pmu: Remove use of perf_cpu_map__read() (bsc#1234698 jsc#PED-12309).
  * perf cpumap: Reduce transitive dependencies on libperf MAX_NR_CPUS
    (bsc#1234698 jsc#PED-12309).
