  perf record: Honor --quiet option properly (2017-02-20 11:50:36 -0300)

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

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:

- 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:

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

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.

Several are cross builds, the ones with -x-ARCH, and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
