While this one looks to be independent of earlier patches in this
series (and hence could be considered a candidate for committing
early), I don't think we want this committed ahead of (to be
extended) patch 3, to avoid having more pages which may get mis-
handled in a few places. It would be nice if in v4 you could add
a respective post-commit-message remark.
