Merge tag 'perf-core-for-mingo-5.3-20190529' 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:

  Jiri Olsa:

  - Preserve eBPF maps when loading kcore.

  - Fix up DSO name padding in 'perf script --call-trace', as BPF DSO names are
    much larger than what we used to have there.

  - Add --show-bpf-events to 'perf script'.

perf trace:

  Arnaldo Carvalho de Melo:

  - Add string table generators and beautify arguments for the new fspick,
    fsmount, fsconfig, fsopen, move_mount and open_tree syscalls, as well
    as new values for arguments of clone and sync_file_range syscalls.

perf version:

  Arnaldo Carvalho de Melo:

  - Append 12 git SHA chars to the version string.

Namespaces:

  Namhyung Kim:

  - Add missing --namespaces option to 'perf top', to generate and process
    namespace events, just like present for 'perf record'.

Intel PT:

  Andrian Hunter:

  - Fix itrace defaults for 'perf script', not using the 'use_browser' variable
    to figure out what options are better for 'script' and 'report'

  - Allow root fixing up buildid cache permissions in the perf-with-kcore.sh
    script when sharing that cache with another user.

  - Improve sync_switch, a facility used to synchronize decoding of HW
    traces more closely with the point in the kerne where a context
    switch took place, by processing the PERF_RECORD_CONTEXT_SWITCH "in"
    metadata records too.

  - Make the exported-sql-viewer.py GUI also support pyside2, which
    upgrades from qt4 used in pyside to qt5. Use the argparser module
    for more easily addition of new command line args.
