Hi Ingo,

	Please consider pulling, should get linux-next free of perf build fixdep
related race conditions on high core count machines,

  perf tools: Explicitly document that --children is enabled by default (2016-12-07 12:00:35 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

Improvements:

- Improve error message when analyzing file with required events in
  'perf sched timehist' (David Ahern)

Fixes:

- Force fixdep compilation to be done at the start of the build, fixing
  some build race conditions in high core count machines (Jiri Olsa)

- Fix handling a zero sample->tid in 'perf sched timehist', as
  sometimes that isn't the idle thread (Namhyung Kim)

Infrastructure:

- Check minimal accepted LLVM version in its feature check, 3.9 at this
  time (Wang Nan)

Documentation:

- Explicitly document that --children is enabled by default (Yannick Brosseau)
