As user pages are always in highmem, this should be easy to decide:

Good point; for a system with at least (say) 2GB of memory, that
definitely makes sense. For a system with less than 768 megs of
memory (how quaint, but it wasn't that long ago this was a lot of
memory :-), there wouldn't *be* any memory in highmem at all....
not to mention machines with 1G of ram (900M lowmem, 128M highmem)
