Merge tag 'perf-core-for-mingo-5.1-20190220' 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:

perf report:

  He Kuang:

  - Don't shadow inlined symbol with different addr range.

perf script:

  Jiri Olsa:

  - Allow +- operator to ask for -F to add/remove fields to
    the default set, for instance to ask for the removal of the
    'cpu' field in tracepoint events, adding 'period' to that
    kind of events, etc.

perf test:

  Thomas Richter:

  - Fix scheduler tracepoint signedness of COMM fields failure of
    'evsel-tp-sched' test on s390 and other arches.

  Tommi Rantala:

  - Skip trace+probe_vfs_getname.sh when 'perf trace' is not built.

perf trace:

  Arnaldo Carvalho de Melo:

  - Add initial BPF map dumper, initially just for the current, minimal
    needs of the augmented_raw_syscalls BPF example used to collect
    pointer args payloads that uses BPF maps for pid and syscall filtering,
    but will in time have features similar to 'perf stat' --interval-print,
    --interval-clear, ways to signal from a BPF event that a specific
    map (or range of that map) should be printed, optionally as a
    histogram, etc.

General:

  Jiri Olsa:

  - Add CPU and NUMA topologies classes for further reuse, fixing some
    issues in the process.

  - Fixup some warnings and debug levels.

  - Make rm_rf() remove single file, not just directories.

Documentation:

  Jonas Rabenstein:

  - Fix HEADER_CMDLINE description in perf.data documentation.

  - Fix documentation of the Flags section in perf.data.
