Merge tag 'perf-core-for-mingo-5.1-20190206' 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:

Hardware tracing:

  Adrian Hunter:

  - Handle calls optimized into jumps to a different symbol
    in the thread stack routines used to process hardware traces (Adrian Hunter)

Intel PT:

  Adrian Hunter:

  - Fix overlap calculation for padding.

  - Fix CYC timestamp calculation after OVF.

  - Packet splitting can only happen in 32-bit.

  - Add timestamp to auxtrace errors.

ARM CoreSight:

  Leo Yan:

  - Add last instruction information in packet

  - Set sample flags for instruction range, exception and
    return packets and for a trace discontinuity.

  - Add exception number in exception packet

  - Change tuple from traceID-CPU# to traceID-metadata

  - Add traceID in packet

  Mathieu Poirier:

  - Add "sinks" group to PMU directory

  - Use event attributes to send sink information to kernel

  - Remove set_drv_config() API, no longer used.

perf annotate:

  Jiri Olsa:

  - Delay symbol annotation to the resort phase, speeding up 'perf report'
    startup.

perf record:

  Alexey Budankov:

  - Allow binding userspace buffers to NUMA nodes.

Symbols:

  Adrian Hunter:

  - Fix calculating of symbol sizes when splitting kallsyms into
    maps for kcore processing.

Vendor events:

  William Cohen:

  - Intel: Fix Load_Miss_Real_Latency on CLX

Misc:

  Arnaldo Carvalho de Melo:

  - Streamline headers, removing includes when all that is needed are
    just forward declarations, fixup the fallout for cases where headers
    should have been explicitely included but were instead obtained
    indirectly, by sheer luck.

  - Add fallback versions for CPU_{OR,EQUAL}(), so that code using it
    continue to build on older systems where those were not yet introduced
    or in systems using some other libc than the GNU one where those
    helpers aren't present.

Documentation:

  Changbin Du:

  - Add documentation for BPF event selection.
