[GIT PULL 0/5] perf/urgent fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	This was ready already before my short vacations, and get things
building on the recently released fedora 27 and make 'perf test' pass
all entries, so please consider pulling,

- Arnaldo

  x86/asm: Allow again using asm.h when building for the 'bpf' clang target (2017-12-15 12:30:16 -0300)

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

- Fix up build in hardened environments, such as fedora 27 (Jiri Olsa)

- Do not include header files from the kernel sources for the s/390 arch,
  fixing the detached tarball building (Arnaldo Carvalho de Melo)

- Allow again using asm.h when building for the 'bpf' clang target,
  guarding x86 specific bits under ifndef __BPF__ (Arnaldo Carvalho de Melo)

- Generate correct debug information for inlined code when generating
  ELF images for JITted java programs (Ben Gainey)

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.

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.

News: Amazon Linux 2 and Ubuntu 18.04 added.
