Actually, I changed my mind.

It isn't useful to ask for different size pages.  QEMU currently does
all-or-nothing.  Even if it did a mix of both, it would need to tell the
guest which areas were which (I really want one of *these* huge pages).

That's too much complexity for a feature which doesn't exist.  So I
prefer the current single-page-size model.

Cheers,
Rusty.
