Merge tag 'perf-core-for-mingo-4.15-20171103' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
- Beautify the 'kcmp' and 'prctl' syscall arguments in 'perf trace'
(Arnaldo Carvalho de Melo)
- Implement a way to print formatted output to per-event files in 'perf script'
to facilitate generate flamegraphs, elliminating the need to write scripts to
do that separation (yuzhoujian, Arnaldo Carvalho de Melo)
Make 'perf stat --per-thread' update shadow stats to show metrics (Jiri Olsa)
- Fix double mapping al->addr in callchain processing for children without self
period (Namhyung Kim)
- Fix memory leak in addr2inlines() when libbfd is not used (Namhyung Kim)
- Show correct function name for srcline of callchains when libbfd is not used
(Namhyung Kim)
