perf intel-pt: Use __fallthrough (2017-02-09 16:32:03 -0300)

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

User visible:

- Add support for parsing Intel uncore vendor event files and add uncore
vendor events for the Intel server processors (Haswell, Broadwell,
IvyBridge), Xeon Phi (Knights Landing) and Broadwell DE (Andi Kleen)

- Support --symfs in 'perf probe' (Uwe Kleine-KÃnig)

- Add support for generating bpf prologue on the aarch64 architecture (He Kuang)

- Show proper hint when SDT event not yet in place via 'perf probe' (Ravi Bangoria)

- Take into account symfs setting when reading file build ID (Victor Kamensky)

Infrastructure:

- Map gcc7's '__attribute__ ((fallthrough))', that warns when code
associated to case blocks in switches continue into the next case entry,
to '__falltrough' and use it where warned by gcc, tested on Fedora Rawhide
(Arnaldo Carvalho de Melo)

- Fix buffer sizes used with snprintf that could lead to truncation,
another warning introduced in gcc7 (Arnaldo Carvalho de Melo)

- Robustify do_generate_dynamic_list_file in libtraceevent (David Carrillo-Cisneros)

- Use zfree() in more places (Taeung Song)

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.
