Hi Ingo,
Please consider pulling, now there are no more ABI header

tools headers powerpc: Remove unistd.h (2019-01-10 10:42:08 -0300)
perf/core fixes and improvements:
perf trace:
Ravi Bangoria:
- Rework PowerPC syscall table generation, now using a .tbl file just like
x86_64 and S/390, also silencing a tools build warning about headers out of
sync with the kernel sources.
tools include uapi:
Arnaldo Carvalho de Melo:
- Sync linux/if_link.h copy with the kernel sources, silencing a build
warning.
perf top:
Arnaldo Carvalho de Melo:
- Add 'arch_cpu_idle' to the list of kernel idle symbols, noticed on a Orange
Pi Zero ARM board, just like with other symbols in other arches.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
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.
