I added the stable tag to this and the other patch, because the bugs were
regressions introduced in recent kernels, and Michal sugguest we may want
to backport them (but not in a strong feeling).

But surely the bug is extreamly unlikely, and seems we currently want to
be more strictly on what patches should go into stable, I think it's fine
to drop it from stable.
