Merge tag 'perf-core-for-mingo-4.11-20170201' of... 

Merge tag 'perf-core-for-mingo-4.11-20170201' 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:

New features:

- Allow configuring a 'perf ftrace' default --tracer (Taeung Song)

Infrastructure changes:

- Sync tools/arch/{powerpc,arm}/include/uapi/asm/kvm.h and
       tools/arch/x86/include/asm/cpufeatures.h (Ingo Molnar)

- Add BPF program file system pinning APIs and respective
  'perf test' entry (Joe Stringer)

- Make tools tree support 'make -s' (Josh Poimboeuf)

- Reference count maps in callchains, fixing SEGFAULT when
  referencing maps after it is freed (Krister Johansen)

- Create for_each_event trace points iterator (Taeung Song)

- Do not consider an error not to have any perfconfig file
  (Arnaldo Carvalho de Melo

- Propagate perf_config() errors (Arnaldo Carvalho de Melo)
