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

Pull perf/urgent fix from Arnaldo Carvalho de Melo:

  - Fix 'perf diff' initialization, calling the recently added hists__init()
    function so that extra space is allocated per perf_evsel for the hists storage
    that it also uses, just like report and top.  (Kan Liang)
