Merge tag 'perf-core-for-mingo-5.1-20190214' 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 list:

  Jiri Olsa:

  - Display metric expressions for --details option

perf record:

  Alexey Budankov:

  - Implement --affinity=node|cpu option, leftover, the other patches
    in this kit were already applied.

perf trace:

  Arnaldo Carvalho de Melo:

  - Fix segfaults due to not properly handling negative file descriptor syscall args.

  - Fix segfault related to the 'waitid' 'options' prefix showing logic.

  - Filter out 'gnome-terminal*' if it is a parent of 'perf trace', to reduce the
    syscall feedback loop in system wide sessions.

BPF:

  Song Liu:

  - Silence "Couldn't synthesize bpf events" warning for EPERM.

Build system:

  Arnaldo Carvalho de Melo:

  - Fix the test-all.c feature detection fast path that was broken for
    quite a while leading to longer build times.

Event parsing:

  Jiri Olsa:

  - Fix legacy events symbol separator parsing

cs-etm:

  Mathieu Poirier:

  - Fix some error path return errors and plug some memory leaks.

  - Add proper header file for symbols

  - Remove unused structure fields.

  - Modularize auxtrace_buffer fetch, decoder and packet processing loop.

Vendor events:

  Paul Clarke:

  - Add assorted metrics for the Power8 and Power9 architectures.

perf report:

  Thomas Richter:

  - Add s390 diagnostic sampling descriptor size
