Subject: [PATCHSET 00/12] perf test: Add test workloads (v1)

Hello,

In the shell tests, it needs to run a custom test workload to verify
the behaviors.  This requires a working compiler when it runs the
tests.  However it's not available in some test environments, making
hard to run those tests.

So I've added the test workload to the perf binary directly, so that
we can run them simply like:

  $ perf test -w noploop

And convert most of the shell tests need compilers with this workloads.
The buildid test still requires a compiler since it needs to check
different build options to generate different kind of build-IDs.

I've checked perf test result after the changes but could not verify
architecture-specific ones (e.g. for arm64).  It'd be nice if anyone
can check it out.

You can find it in 'perf/test-workload-v1' branch in

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks,
Namhyung
