Hmmm. There aren't _that_ many of those cases, right? Are there any
that absolutely need raw access to the buddy allocator? I'm pretty sure
that pagetables can be moved over to a slab, as long as we bump up the
alignment.
It does seem a wee bit silly to have the pointer in _all_ of the struct
pages, even the ones for which we will never do any accounting (and even
on kernels that never need it). But, a hashing scheme sounds like a
fine idea.
