Merge tag 'perf-core-for-mingo-5.5-20191119' 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:

x86/insn:

  Adrian Hunter:

  - Add some more Intel instructions to the opcode map:

        cldemote, encls, enclu, enclv, enqcmd, enqcmds, movdir64b,
        movdiri, pconfig, tpause, umonitor, umwait, wbnoinvd.

  - The instruction decoding can be tested using the perf tools'
    "x86 instruction decoder - new instructions" test as folllows:

    $ perf test -v "new " 2>&1 | grep -i cldemote
    Decoded ok: 0f 1c 00                    cldemote (%eax)
    Decoded ok: 0f 1c 05 78 56 34 12        cldemote 0x12345678
    Decoded ok: 0f 1c 84 c8 78 56 34 12     cldemote 0x12345678(%eax,%ecx,8)
    Decoded ok: 0f 1c 00                    cldemote (%rax)
    Decoded ok: 41 0f 1c 00                 cldemote (%r8)
    Decoded ok: 0f 1c 04 25 78 56 34 12     cldemote 0x12345678
    Decoded ok: 0f 1c 84 c8 78 56 34 12     cldemote 0x12345678(%rax,%rcx,8)
    Decoded ok: 41 0f 1c 84 c8 78 56 34 12  cldemote 0x12345678(%r8,%rcx,8)
    $ perf test -v "new " 2>&1 | grep -i tpause
    Decoded ok: 66 0f ae f3                 tpause %ebx
    Decoded ok: 66 0f ae f3                 tpause %ebx
    Decoded ok: 66 41 0f ae f0              tpause %r8d

callchains:

  Adrian Hunter:

  - Fix segfault in thread__resolve_callchain_sample().

perf probe:

  - Line fixes to show only lines where probes can be used with 'perf probe -L',
    and when reporting them via 'perf probe -l'.

  - Support multiprobe events.

perf scripts python:

  Adrian Hunter:

  - Fix use of TRUE with SQLite < 3.23 in exported-sql-viewer.py.

perf maps:

  - Trim 'struct map' by removing the rb_node member for sorting
    by map name, as that is only needed for processing kernel maps,
    and only when classifying symbols by section at load time.
    Sort them by name using qsort() and do lookups using bsearch()
    when map_groups__find_by_name() is used.

perf parse:

  Ian Rogers:

  - Report initial event parsing error, providing a less cryptic message
    to state that a PMU wasn't found in the system.

perf vendor events:

  James Clark:

  - Fix commas so that PMU event files for arm64, power8 and power nine
    become valid JSON.

libtraceevent:

  Konstantin Khlebnikov:

  - Fix parsing of event %o and %X argument types.
