Merge tag 'perf-core-for-mingo-4.11-20170126' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull the latest perf/core updates from Arnaldo Carvalho de Melo:
New features:
- Introduce 'perf ftrace' a perf front end to the kernel's ftrace
function and function_graph tracer, defaulting to the "function_graph"
tracer, more work will be done in reviving this effort, forward porting
it from its initial patch submission (Namhyung Kim)
- Add 'e' and 'c' hotkeys to expand/collapse call chains for a single
hist entry in the 'perf report' and 'perf top' TUI (Jiri Olsa)
Fixes:
- Fix wrong register name for arm64, used in 'perf probe' (He Kuang)
- Fix map offsets in relocation in libbpf (Joe Stringer)
- Fix looking up dwarf unwind stack info (Matija Glavinic Pecotic)
Infrastructure changes:
- libbpf prog functions sync with what is exported via uapi (Joe Stringer)
Trivial changes:
- Remove unnecessary checks and assignments in 'perf probe's
try_to_find_absolute_address() (Markus Elfring)
