Of course, it will still work with 4kB pages, and the guest can still 
whatever page size it wants, including 64kB. Not very good from a 
point of view, but it will work.

My main worry is that we're already starting to see more and more 
having divergent requirements in their MM setup, and distributions are 
to struggle to provide a full-featured single kernel image, specially 
as some
feel the need to push 64kB pages down to everybody's throat.


Fast, cheap, reliable. Pick two.
