Currently, 'perf record -- sleep 1' creates a cpu map for all online cpus since it turns out calling cpu_map__new(NULL). Fix it. Also it is guaranteed that cpu_list is NULL if PID/TID is given by calling perf_target__validate(), so we can make the conditional bit simpler. This also fixes perf test 7 (Validate) failure on my 6 core machine: $ cat /sys/devices/system/cpu/online 0-11 $ ./perf test -v 7 7: Validate PERF_RECORD_* events & perf_sample fields: --- start --- perf_evlist__mmap: Operation not permitted ---- end ---- Validate PERF_RECORD_* events & perf_sample fields: FAILED!
