I _think_ we can apply this patch in the end. But there is more work to
be done before we can do that. PPC is probably broken in that regard as
well, we just haven't noticed before this got merged. I find the
hwpoison based reasons for merging disputable at best but this is not
serious enough to call for a revert. I am currently working on patches
to make giga pages migratable for real and then we can apply your patch
on top.
