It doesn't impossible. Just nobody did. I was playing these code as a
maintainer a while
and I saw all of patches doesn't handle highmem correctly. But I
didn't refuse because
I know it's not a regression.

But, if you guys have a strong motivation, it's a very good news. I
have no objection not to mark it broken and accept your contributions.
