Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Conflicts:
	tools/Makefile

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

. Honor parallel jobs, fix from Borislav Petkov

. Introduce tools/lib/lk library, initially just removing duplication
  among tools/perf and tools/vm. from Borislav Petkov

. Fix build on non-glibc systems due to libio.h absence, from Cody P Schafer.

. Remove some perf_session and tracing dead code, from David Ahern.

. Introduce perf stat --repeat forever, from Frederik Deweerdt.

. Add perf test entries for checking --cpu in record and stat, from Jiri Olsa.

. Add perf test entries for checking breakpoint overflow signal handler issues,
  from Jiri Olsa.

. Add perf test entry for for checking number of EXIT events, from Namhyung Kim.

. Simplify some perf_evlist methods and to allow 'stat' to share code with
  'record' and 'trace'.

. Remove dead code in related to libtraceevent integration, from Namhyung Kim.

. Event group view for 'annotate' in --stdio, --tui and --gtk, from Namhyung Kim.
