Hi Ingo,
I merged tip/perf/urgent into tip/perf/core before rebasing with these
patches, please consider pulling,

perf config: Refactor the code using 'ret' variable in cmd_config() (2017-06-19 22:05:55 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Allow adding and removing fields to the default 'perf script' columns,
using + or - as field prefixes to do so (Andi Kleen)
- Display titles in left frame in the annotate browser (Jin Yao)
- Allow resolving the DSO name with 'perf script -F brstack{sym,off},dso'
(Mark Santaniello)
- Support function filtering in 'perf ftrace' (Namhyung Kim)
- Allow specifying function call depth in 'perf ftrace' (Namhyumg Kim)
Infrastructure:
- Adopt __noreturn, __printf, __scanf, noinline, __packed and __aligned
__alignment__(()) markers, to make the tools/ source code base to be
more compact and look more like kernel code (Arnaldo Carvalho de Melo)
- Remove unnecessary check in annotate_browser_write() (Jin Yao)
- Return arch from symbol__disassemble() so that callers, such as
the annotate TUI browser to use arch specific formattings, such
as the upcoming instruction micro-op fusion on Intel Core (Jin Yao)
- Remove superfluous check before use in the coresight code base (Kim
Phillips)
- Remove unused SAMPLE_SIZE defines and BTS priv array (Kim Phillips)
- Error handling fix/tidy ups in 'perf config' (Taeung Song)
- Avoid error in the BPF proggie built with clang in 'perf test llvm'
when PROFILE_ALL_BRANCHES is set (Wang Nan)

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.
