Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

- Fix segfault pressing -> in 'perf top' with no hist entries. (Wang Nan)

   E.g:
	perf top -e page-faults --pid 11400 # 11400 generates no page-fault

- Fix propagation of thread and cpu maps, that got broken when doing incomplete
  changes to better support events with a PMU cpu mask, leading to Intel PT to
  fail with an error like:

    $ perf record -e intel_pt//u uname
    Error: The sys_perf_event_open() syscall returned with
              22 (Invalid argument) for event (sched:sched_switch).

  Because intel_pt adds that sched:sched_switch evsel to the evlist after the
  thread/cpu maps were propagated to the evsels, fix it. (Adrian Hunter)
