Add a .kunitconfig file, which provides a default, working config for running the KCSAN tests. Note that it needs to run on an SMP machine, so to run under kunit_tool, the --qemu_args option should be used (on a supported architecture, like x86_64). For example: ./tools/testing/kunit/kunit.py run --arch=x86_64 --qemu_args='-smp 8' --kunitconfig=kernel/kcsan Signed-off-by: David Gow <davidgow@google.com> Reviewed-by: Marco Elver <elver@google.com> Acked-by: Brendan Higgins <brendanhiggins@google.com> Tested-by: Daniel Latypov <dlatypov@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
