Merge tag 'perf-core-for-mingo-5.0-20190126' 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:

BPF:

  Song Liu:

  - Fix synthesized PERF_RECORD_KSYMBOL/BPF_EVENT

  Arnaldo Carvalho de Melo:

  - Add bpf_map() helper, to make BPF map declararions more compact and
    allow for BTF annotations to be made transparently.

perf script python:

  Tony Jones:

  - Remove explicit shebangs.

  - Fix the PYTHON=python3 builds.

Core:

  Davidlohr Bueso:

  - Update rbtree implementation, getting it closer to the kernel one.

  - Use cached rbtrees.

  Arnaldo Carvalho de Melo:

  - Remove some needless headers from .c and .h files fixing up the fallout,
    to reduce building time when changes are made to .h files
