For this I'd suggest that you start with a conceptual model rather than
thinking of patches straight away. It has been the topic of past
discussions, without - iirc - conclusive results. I'm sure you're aware
that 4k page size is, sadly, baked into certain parts of the public
interface (see e.g. io/ring.h). Otoh it may well be that you're goal is
explicitly not to be able to run any guests working with 4k pages. If
so, what would need ensuring is that such guests would cleanly fail to
start, rather than crash early in a cryptic way.
