Good question.

This one isn't really bad (yet), but there are other build and qemu test breakages
which have been in -next, sometimes for a long period of time, with patches
submitted but ignored by the maintainers. Those are creeping into mainline now.

Wonder if I (or someone else) should just collect those patches and send
a pull request to Linus right after (or even before) -rc1.
