Merge tag 'perf-core-for-mingo-4.11-20170220' of... 

Merge tag 'perf-core-for-mingo-4.11-20170220' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

 into perf/urgent

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

New features:

 - Make -a/--all-cpus be the default target in 'perf record' and 'perf stat',
   just like it is with 'perf trace' (Jiri Olsa)

 - Introduce -q/--quiet to the 'annotate', 'diff' and 'report', fix up
   its behaviour in 'record'. This makes the output more compact by
   elliminating headers, leaving just the histogram lines (Namhyung Kim)

Fixes:

 - Handle offline/absent CPUs (Jan Stancek)

Infrastructure changes:

 - Filter out -specs=/a/b/c from CC options when building the python
   support, allowing that feature to be built with clang (Arnaldo Carvalho de Melo)

 - Fix DEBUG=1 build with clang (Arnaldo Carvalho de Melo)

Trivial changes:

 - Fix spelling of 'preempt' in a libtraceevent function name (Steven Rostedt)
