Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: * Add summary only option to 'perf trace', suppressing the decoding of events, from David Ahern * 'perf trace --summary' formatting simplifications, from Pekka Emberg. * Beautify fifth argument of mmap() as fd, in 'perf trace', from Namhyung Kim. * Fix segfault on perf trace -i perf.data, from Namhyung Kim. * Fix segfault with --no-mmap-pages, from David Ahern. * Round mmap pages to power 2, from David Ahern. * Add direct access to dynamic arrays in libtraceevent, from Steven Rostedt. * Handle throttle events in 'object code reading' test, fix from Adrian Hunter. * Prevent condition that all sort keys are elided, fix from Namhyung Kim. * Synthesize non-exec MMAP records when --data used, allowing the resolution of data addresses to symbols (global variables, etc). * 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. * Code cleanups by David Ahern and Adrian Hunter.
