Merge tag 'perf-core-for-mingo-4.12-20170314' of git://git./linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

New features:

- Add PERF_RECORD_NAMESPACES so that the kernel can record information
  required to associate samples to namespaces, helping in container
  problem characterization.

  Now the 'perf record has a --namespace' option to ask for such info,
  and when present, it can be used, initially, via a new sort order,
  'cgroup_id', allowing histogram entry bucketization by a (device, inode)
  based cgroup identifier (Hari Bathini)

- Add --next option to 'perf sched timehist', showing what is the next
  thread to run (Brendan Gregg)

Fixes:

- Fix segfault with basic block 'cycles' sort dimension (Changbin Du)

- Add c2c to command-list.txt, making it appear in the 'perf help'
  output (Changbin Du)

- Fix zeroing of 'abs_path' variable in the perf hists browser switch
  file code (Changbin Du)

- Hide tips messages when -q/--quiet is given to 'perf report' (Namhyung Kim)

Infrastructure changes:

- Use ref_reloc_sym + offset to setup kretprobes (Naveen Rao)

- Ignore generated files pmu-events/{jevents,pmu-events.c} for git (Changbin Du)

Documentation changes:

- Document +field style argument support for --field option (Changbin Du)

- Clarify 'perf c2c --stats' help message (Namhyung Kim)
