  perf vendor events: Add Goldmont Plus V1 event file (2017-10-23 16:30:54 -0300)

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

- Update vendor events JSON metrics for Intel's Broadwell, Broadwell
  Server, Haswell, Haswell Server, IvyBridge, IvyTown, JakeTown, Sandy
  Bridge, Skylake and SkyLake Server (Andi Kleen)

- Add vendor event file for Intel's Goldmont Plus V1 (Kan Liang)

- Move perf_mmap methods from 'perf record' and evlist.c to a separate
  mmap.[ch] pair, to better separate things and pave the way for further
  work on multithreading tools (Arnaldo Carvalho de Melo)

- Do not check ABI headers in a detached tarball build, as it the kernel
  headers from where we copied tools/include/ are by definition not
  available (Arnaldo Carvalho de Melo)

- Make 'perf script' use fprintf() like printing, i.e. receiving a FILE
  pointer so that it gets consistent with other tools/ code and allows
  for printing to per-event files (Arnaldo Carvalho de Melo)

- Error handling fixes (resource release on exit) for 'perf script'
  and 'perf kmem' (Christophe JAILLET)

- Make some 'perf event attr' tests optional on virtual machines, where
  tested counters are not available (Jiri Olsa)

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.
