The solution I am working on for how to support Linux hugepages (Xen superpages) involves creating domains made up entirely of superpages. I can create a working domain with superpages and am in the process of supporting it in save/restore.

This wouldn't work too well for me in the case of thread stacks because we need to map out parts of the stack and, although we want large virtual stacks, we don't want do dedicate that much physical memory. Is it really difficult to support mixed pages sizes in the general case, e.g., save/restore etc.?
