Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
 "A number of fixes:

   - Fix segfault on perf trace -i perf.data, from Namhyung Kim.

   - Fix segfault with --no-mmap-pages, from David Ahern.

   - Don't force a refresh during progress update in the TUI, greatly
     reducing startup costs, fix from Patrick Palka.

   - Fix sw clock event period test wrt not checking if using >
     max_sample_freq.

   - Handle throttle events in 'object code reading' test, fix from
     Adrian Hunter.

   - Prevent condition that all sort keys are elided, fix from Namhyung
     Kim.

   - Round mmap pages to power 2, from David Ahern.

  And a number of late arrival changes:

   - Add summary only option to 'perf trace', suppressing the decoding
     of events, from David Ahern

   - 'perf trace --summary' formatting simplifications, from Pekka
     Enberg.

   - Beautify fifth argument of mmap() as fd, in 'perf trace', from
     Namhyung Kim.

   - Add direct access to dynamic arrays in libtraceevent, from Steven
     Rostedt.

   - Synthesize non-exec MMAP records when --data used, allowing the
     resolution of data addresses to symbols (global variables, etc), by
     Arnaldo Carvalho de Melo.

   - Code cleanups by David Ahern and Adrian Hunter"
