Merge tag 'perf-urgent-for-mingo-5.4-20191105' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

 into perf/urgent

Pull perf fixes from Arnaldo Carvalho de Melo:

perf report/top:

  Jiri Olsa:

  - Fix time sorting for big numbers, i.e.:

    perf report -s time -F time,overhead --stdio

  was failing because the sort comparision routine was returning 'int' while
  that particular -s key was int64_t, fix it.

perf scripting engines:

  Steven Rostedt (VMware):

  - Iterate on tep event arrays directly, fixing a bug when generating python/perl
    source code from a perf.data file with more than one tracepoint event.
