I don't think you need to do anything.  You've provided the selftest
code for the arch maintainers and the arch maintainers will get
"membarrier not implemented" warnings each time they build a kernel. 
The idea is that when they have time they'll wire it up, run the tests
then ship it.

If you want to help that process along a bit you could send patches to
the arch maintainers along with instructions on how to test the
syscall.  The less work they have to do, the more likely they are
to do it ;)
