Subject: [GIT PULL 00/19] perf/core improvements and fixes

Hi Ingo,

	A bit of trivia info is now automatically shown in the container
builds, the gcc version used to build the tools, that gets changed as
the distros update gcc and as I update the container build images :-)

	Please consider pulling,

- Arnaldo

  perf srcline: Show correct function name for srcline of callchains (2017-11-01 11:44:38 -0300)

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

- Beautify the 'kcmp' and 'prctl' syscall arguments in 'perf trace'
  (Arnaldo Carvalho de Melo)

- Implement a way to print formatted output to per-event files in 'perf script'
  to facilitate generate flamegraphs, elliminating the need to write scripts to
  do that separation (yuzhoujian, Arnaldo Carvalho de Melo)

  Make 'perf stat --per-thread' update shadow stats to show metrics (Jiri Olsa)

- Fix double mapping al->addr in callchain processing for children without self
  period (Namhyung Kim)

- Fix memory leak in addr2inlines() when libbfd is not used (Namhyung Kim)

- Show correct function name for srcline of callchains when libbfd is not used
  (Namhyung Kim)

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.
