Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Fixes and improvements for perf/core:
. Overhaul the tools/ makefiles, gluing them to the top level Makefile, from
Borislav Petkov.
. Move the UI files from tools/perf/util/ui/ to tools/perf/ui/. Also move
the GTK+ browser to tools/perf/ui/gtk/, from Namhyung Kim.
. Only fallback to sw cycles counter on ENOENT for the hw cycles, from
Robert Richter
. Trivial fixes from Robert Richter
. Handle the autogenerated bison/flex files better, from Namhyung and Jiri Olsa.
. Navigate jump instructions in the annotate browser, just press enter or ->,
still needs support for a jump navigation history, i.e. to go back.
. Search string in the annotate browser: same keys as vim:
/ forward
n next backward/forward
? backward
. Clarify number of events/samples in the report header, from Ashay Rane
