  perf record: Combine some auxtrace initialization into a single function 
(2018-03-06 12:03:39 -0300)

----------------------------------------------------------------
perf/urgent fixes:

- Be more robust when drawing arrows in the annotation TUI, avoiding a
  segfault when jump instructions have as a target addresses in functions
  other that the one currently being annotated. The full fix will come in
  the following days, when jumping to other functions will work as call
  instructions (Arnaldo Carvalho de Melo)

- Prevent auxtrace_queues__process_index() from queuing AUX area data for
  decoding when the --no-itrace option has been used (Adrian Hunter)

- Sync copy of kvm UAPI headers and x86's cpufeatures.h (Arnaldo Carvalho de 
Melo)

- Fix 'perf stat' CVS output format for non-supported counters (Ilya Pronin)

- Fix crash in 'perf record|perf report' pipe mode (Jiri Olsa)

- Fix annoying 'perf top' overwrite fallback message on older kernels (Kan 
Liang)

- Fix the usage on the 'perf kallsyms' man page (Sangwon Hong)

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support.  Where clang is available, it is also used to build
perf with/without libelf.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container 
cluster.
Those will come back later.

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.
