Merge tag 'perf-core-for-mingo-5.5-20190925' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

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

perf record:

  Stephane Eranian:

  - Fix priv level with branch sampling for paranoid=2, i.e. the kernel checks
    if perf_event_attr_attr.exclude_hv is set in addition to .exclude_kernel,
    so reset both to zero.

  Arnaldo Carvalho de Melo:

  - Don't warn about not being able to read kernel maps (kallsyms, etc) when
    kernel samples aren't being collected.

perf list:

  Kim Phillips:

  - Allow plurals for metric, metricgroup., i.e.:

    $ perf list metrics

    was showing nothing, which is very confusing, make it work like:

    $ perf stat metric

perf stat:

  Andi Kleen:

  - Free memory access/leaks detected via valgrind, related to metrics.

Libraries:

libperf:

  Jiri Olsa:

  - Move more stuff from tools/perf, this time a first stab at moving perf_mmap
    methods.

libtracevent:

  Steven Rostedt (VMware):

  - Round up in tep_print_event() time precision.

  Tzvetomir Stoyanov (VMware):

  - Man pages for event print and related and plugins APIs.

  - Move traceevent plugins in its own subdirectory.

Feature detection:

  Thomas Richter:

  - Add detection of java-11-openjdk-devel package, in addition to the older
    versions supported.

Architecture specific:

S/390:

  Thomas Richter (2):

  - Include JVMTI support for s390

Vendor events:

AMD:

  Kim Phillips:

  - Add L3 cache events for Family 17h.

  - Remove redundant '['.

PowerPC:

  Mamatha Inamdar:

  - Remove P8 HW events which are not supported.

Cleanups:

  Arnaldo Carvalho de Melo:

  - Remove needless headers, add needed ones, move things around to reduce the
    headers dependency tree, speeding up builds by not doing needless compiles
    when unrelated stuff gets changed.

  - Ditch unused code that was dragging headers.
