Merge tag 'perf-core-for-mingo-4.14-20170725' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvemends and fixes for v4.14:

New features:

- Filter out 'sshd' in the tracer ancestry in 'perf trace' syswide tracing,
  to elliminate tracing loops (Arnaldo Carvalho de Melo)

- Support lookup of symbols in other mount namespaces in 'perf top' (Krister Johansen)

- Initial 'clone' syscall args beautifier in 'perf trace' (Arnaldo Carvalho de Melo)

User visible changes:

- Ignore 'fd' and 'offset' args for MAP_ANONYMOUS in 'perf trace'
  (Arnaldo Carvalho de Melo)

- Process tracing data in 'perf annotate' pipe mode (David Carrillo-Cisneros)

- Make 'perf report --branch-history' work without callgraphs(-g) option
  in perf record (Jin Yao)

- Tag branch type/flag on "to" and tag cycles on "from" in 'perf report' (Jin Yao)

Fixes:

- Fix jvmti linker error when libelf config is disabled (Sudeep Holla)

- Fix cgroups refcount usage (Arnaldo Carvalho de Melo)

- Fix kernel symbol adjustment for s390x (Thomas Richter)

- Fix 'perf report --stdio --show-total-period', it was showing the
  number of samples, not the total period (Taeung Song)

Infrastructure changes:

- Add perf_sample dictionary to tracepoint handlers in 'perf script'
  python, which were already present for other types of events
  (hardware, etc) (Arun Kalyanasundaram)

- Make build fail on vendor events JSON parse error (Andi Kleen)

- Adopt strstarts() from the kernel (Arnaldo Carvalho de Melo)

Arch specific changes:

- Set no_aux_samples for the tracking event in Intel PT (Kan Liang)

- Always set no branch for Intel PT dummy event (Kan Liang)

Trivial changes:

- Simplify some error handlers in 'perf script' (Dan Carpenter)

- Add EXCLUDE_EXTLIBS and EXTRA_PERFLIBS to makefile (David Carrillo-Cisneros)
