OK, if any of the arch maintainers wishes to submit the patch to 3.6,
they are free to do so -- just let me know and I will drop the patch from
my tree.

That said, all this does is cause spurious warnings to be printed, so
not sure it really qualifies as serious. But I am happy to leave that
decision with the individual arch maintainers -- it is their arch,
after all, so their decision.

Thanx, Paul
