[GIT PULL 00/11] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	There are some 'perf test' and container failures, but those
don't seem to have been introduced by patches in this series and are
being investigated.

	Please consider pulling,

- Arnaldo

  perf intel-pt: Bring instruction decoder files into line with the kernel (2017-11-23 15:40:48 -0300)

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

- Improve build messages for Intel PT related files that differ
  from the kernel (Adrian Hunter)

- Bring instruction decoder files into line with the kernel (Adrian Hunter)

- Allow computing 'perf stat' style metrics in 'perf script' (Andi Kleen)

- Fix -D output for user metadata events (Arnaldo Carvalho de Melo)

- Add perf tools tip for using 'perf buildid-cache' to add the Node.js
  USDT probes and have them usable via 'perf probe' (Hansuk Hong)

- Follow the upstream kernel UAPI header version 100% (Ingo Molnar)

- Fixup discontiguous/sparse numa nodes in 'perf bench numa' (Satheesh Rajendran)

- Fix a 'perf test' case and disable one, both for s390x (Thomas Richter)

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.
