min_state areas for MCA will be smaller than a page ... so *my* use
of this allocator doesn't require multi-page.
You know best whether fetchop() will ever want more than a page.
So far, nobody else has leapt out of the woods to claim any other
uses for UC memory (that's a cue for anyone waiting to jump into this
discussion).
We could plan ahead for hypothetical future multi-page users by
defining a "size" argument to alloc/free, but keep our (your) life
simple for now by only implementing the one-page-at-a-time usage
model.
