<proposes to use arm mmu domains to share l1 page tables>

Hm. Interesting idea. The other proposed solution would be to do l1 page
table stealing.

For that, it was proposed that only pmaps without wired page entries should
be candidates - however I don't know whether this is an absolute requirement
or only an optimization. I suspect it would be a requirement for your metho=
d,
too. Can somebody throw in some enlightment here?
