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

  - Accept a zero --itrace period, meaning "as often as possible".  In the case
    of Intel PT that is the same as a period of 1 and a unit of 'instructions'
    (i.e.  --itrace=i1i). (Adrian Hunter)

  - Harmonize itrace's synthesized callchains with the existing --max-stack
    tool option. (Adrian Hunter)

  - Allow time to be displayed in nanoseconds in 'perf script'. (Adrian Hunter)

  - Fix potential infinite loop when handling Intel PT timestamps. (Adrian Hunter)

  - Slighly improve Intel PT debug logging. (Adrian Hunter)

  - Warn when AUX data has been lost, just like when processing PERF_RECORD_LOST.
    (Adrian Hunter)

  - Further document export-to-postgresql.py script. (Adrian Hunter)

  - Add option to synthesize branch stack from auxtrace data. (Adrian Hunter)

  - Use equivalent logic to avoid using dso->kernel. (Arnaldo Carvalho de Melo)

  - Show proper error messages when parsing bad terms for hw/sw events. (He Kuang)

  - Tracepoint event parsing improvements. (He Kuang)

  - Store tracing mountpoint for better error message. (Jiri Olsa)

  - Add fixdep to tools/build, bringing it closer to the kernel counterpart, from
    where it is being lifted. (Jiri Olsa)
