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"
