The following changes since commit 02e184476eff848273826c1d6617bb37e5bcc7ad:

perf tools: Fix maps__find_symbol_by_name() (2018-09-11 14:12:51 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- Fix finding a symbol by name when multiple maps use the same backing DSO,
so we must first see if that symbol name is in the DSO, then see if it is
inside the range of addresses for that specific map (Adrian Hunter)
- Update the tools copies of UAPI headers, which silences the warnings
emitted when building the tools and in some cases, like for the new
KVM ioctls, results in 'perf trace' being able to translate that
ioctl number to a string (Arnaldo Carvalho de Melo)

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.
The alpine ones are failing due to a XSI/POSIX/GNU disagreement on how
strerror_r() should be implemented, a fix is in the works to make libbpf to use
the str_error_r() that tools/perf/ has been using to work on libraries such as
MUSL, that Alpine Linux uses. This problem was not introduced by any patch in
this series.
