Hi Ingo,

Please consider pulling, some from before the trip to Vancouver,
some that were more easy to process before I continue with the backlog.
Took a bit more time than I antecipated due to fixing build breakage in
various places due to multiple patches. This has tip/perf/urgent
merged.

- Arnaldo

perf pmu: Move *_cpuid_str() weak functions to header.c (2018-11-21 22:39:59 -0300)

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

- Start using BPF maps in 'perf trace' for filters in the augmented syscalls
code, keeping the existing code for tracepoint filters so that we can switch
back and forth while getting everything BPFied (Arnaldo Carvalho de Melo)

- Suppress potential format-truncation warning in the PMU code (Ben Hutchings)

- Introduce 'perf bench epoll', with "wait" and "ctl" benchmarks (Davidlohr Bueso)

- Fix slowness due to -ffunction-section, do it by sorting the maps by name, so
avoiding the using rb_first/next to traverse all entries looking for a map name,
that with --ffunction-section gets to thousands of maps (Eric Saint-Etienne)

- Separate jvmti cmlr check (Jiri Olsa)

- Allow using the stepping when figuring out which JSON files to use for a x86
processor, so that Cascadelake server can be support, which has the same
cpuid as some other processor, being different only in the stepping (Kan Liang)

- Share code and output format for uregs and iregs 'perf script' output (Milian Wolff)

- Use perf_evsel__is_clocki() for clock events in 'perf stat' (Ravi Bangoria)

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, 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.
