Merge tag 'perf-core-for-mingo-5.1-20190307' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/core changes from Arnaldo Carvalho de Melo:

perf bpf:

  Arnaldo Carvalho de Melo:

  - Automatically add BTF ELF markers to 'perf trace' BPF programs, so that
    tools such as 'bpftool map dump' can pretty print map keys and values.

perf c2c:

  Jiri Olsa:

  - Fix report for empty NUMA node.

perf diff:

  Jin Yao:

  - Support --time, --cpu, --pid and --tid filter options.

perf probe:

  Arnaldo Carvalho de Melo:

  - Clarify error message about not finding kernel modules debuginfo.

perf record:

  Jiri Olsa:

  - Fixup probing for max attr.precise_ip.

perf trace:

  Arnaldo Carvalho de Melo:

  - Add missing %s lost in the 'msg_flags' recvmmsg arg when adding prefix suppression logic.

perf annotate:

  Arnaldo Carvalho de Melo:

  - Calculate the max instruction name, align column to that, removing the
    hardcoded max 6 chars and cope with instructions with names longer than that,
    such as vpmovmskb, vpcmpeqb, etc.

kernel:

  Song Liu:

  - Consider events with attr.bpf_event set as side-band.

  Gustavo A. R. Silva:

  - Mark expected switch fall-through in perf_event_parse_addr_filter().

Libraries:

  Jiri Olsa:

  - Fix leaks and double frees on error paths.

libtraceevent:

  Tony Jones:

  - Fix buffer overflow in arg_eval().

python scripting:

  Tony Jones:

  - More python3 fixes.

Trivial:

  Yang Wei:

  - Remove needless extra semicolon in clang C++ glue code.

Intel PT/BTS:

  Adrian Hunter:

  - Improve auxtrace address filter error message when there is no DSO.

  - Fix divide by zero when TSC is not available.

  - Further improvements to the export to sqlite/posgresql python scripts
    and to the GUI sqlviewer, exporting 'parent_id' so that we have enable
    the creation of call trees.

  Andi Kleen:

  - Generalize function to copy from thread addr space from intel-bts code.
