Hi Ingo,

	Please consider pulling, there are quite a few patches, but that is
because Adrian did the right thing and made his patches very granular, thanks
Adrian!

  perf tests: Fix software clock events test setting maps (2015-09-15 11:04:49 -0300)

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

User visible:

- Fix segfault pressing -> in 'perf top' with no hist entries (Wang Nan)

   E.g:
	perf top -e page-faults --pid 11400 # 11400 generates no page-fault

- Fix propagation of thread and cpu maps, that got broken when doing incomplete
  changes to better support events with a PMU cpu mask, leading to Intel PT to
  fail with an error like:

  $ perf record -e intel_pt//u uname
  Error: The sys_perf_event_open() syscall returned with
          22 (Invalid argument) for event (sched:sched_switch).

  Because intel_pt adds that sched:sched_switch evsel to the evlist after the
  thread/cpu maps were propagated to the evsels, fix it (Adrian Hunter)

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.
Where clang is available, it is also used to build perf with/without libelf.

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.
