Merge tag 'perf-core-for-mingo' 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:
* Convert callchain children list to rbtree, greatly reducing the time
taken for callchain processing, from Namhyung Kim.
* Add --max-stack option to limit callchain stack scan in 'top' and 'report',
improving callchain processing when reducing the stack depth is an option,
from Waiman Long.
* Compare dso's also when comparing symbols, to avoid grouping together
symbols with the same name but on different DSOs, fix from Namhyung Kim.
* 'perf trace' now can can use a 'perf probe' wannabe tracepoint to hook into
the userspace -> kernel pathname copy so that it can map fds to pathnames
without reading /proc/pid/fd/ symlinks. From Arnaldo Carvalho de Melo.
* 'perf trace' now emits hints as to why tracing is not possible, helping the
user to setup the system to allow tracing in the desired permission
granularity, telling if the problem is due to debugfs not being mounted or
with not enough permission for !root, /proc/sys/kernel/perf_event_paranoit
value, etc. From Arnaldo Carvalho de Melo.
* Add missing 'mmap2' in evsel debug print, from Adrian Hunter.
* Add missing decrement in id sample parsing, not a fix per se, just to
avoid a problem whem somebody adds another field, from Adrian Hunter.
* Improve write_output error message in 'perf record', from Adrian Hunter.
* Add missing sample flush for piped events, fix from Adrian Hunter.
* Add missing members to perf_event__attr_swap(), fix from Adrian Hunter.
* Assorted fixes for 32-bit build, from Adrian Hunter
* Print addr by default for BTS in 'perf script', from Adrian Juntmer
* Separating data file properties from session, code reorganization from
Jiri Olsa.
* Show error in 'perf list' if tracepoints not available, from Pekka Enberg.
