Merge tag 'perf-core-for-mingo-20160623' of... 

Merge tag 'perf-core-for-mingo-20160623' 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:

New features:

- Add 'callindent' option to 'perf script -F', to indent the Intel PT
  call stack, making this output more ftrace-like (Adrian Hunter, Andi Kleen)

User visible changes:

- Enlarge 'pid' column width, to cope with large pids (Jiri Olsa)

Infrastructure changes:

- Fix cross platform unwind (He Kuang)

- Make destructors accept NULL, behaving like free() (Arnaldo Carvalho de Melo)

- Remove reference to perl interpreted in the recently added 'perf script'
  stackcollapse python script (Arnaldo Carvalho de Melo)

- Rename CLASS__for_each() macros to CLASS__for_each_entry(), to use the
  list_for_each_entry() semantics, as most of these class specific loop helpers
  are list_for_each_entry*() wrappers  (Arnaldo Carvalho de Melo)

- Expose the hist_browser code, will be used with data structures other
  than perf_evsel (Jiri Olsa)

- Refactor 'perf config' (Taeung Song)

	Finally, a user may not set fields to none for all event types.
