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

Browse Source 
Pull perf improvements from Arnaldo Carvalho de Melo:

 * Replace event_name with perf_evsel__name, that handles the event
   modifiers and doesn't use static variables.

 * GTK browser improvements, from Namhyung Kim

 * Fix possible NULL pointer deref in the TUI annotate browser, from
   Samuel Liao

 * Add sort by source file:line number, using addr2line.

 * Allow printing histogram text snapshots at any point in top/report.
