Merge tag 'perf-urgent-for-mingo' of git://git./linux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

 * Fix parsing with no sample_id_all bit set, this regression prevents perf
   from reading old perf.data files generated in systems where
   perf_event_attr.sample_id_all isn't available, from Adrian Hunter.

 * Add signal checking to the inner 'perf trace' event processing loop, allowing
   faster response to control+C.

 * Fix formatting of long symbol names removing the hardcoding of a buffer
   size used to format histogram entries, which was truncating the lines.

 * Separate progress bar update when processing events, reducing potentially big
   overhead in not needed TUI progress bar screen updates, from Jiri Olsa.

 * Fix 'perf trace' build in architectures where MAP_32BIT is not defined, from
   Kyle McMartin.
