Well, personally, I'd like to see the whole thing pulled out in
something like

http://www.gelato.unsw.edu.au/archives/linux-ia64/0511/15890.html

(ignore the bug I missed in ivt.S)

I guess it should be sufficient to just do something like

#ifdef CONFIG_PGTABLE_3
#define MAPPED_SPACE_BITS   (3*(PAGE_SHIFT - PTE_BITS) + PAGE_SHIFT)
#elif CONFIG_PGTABLE_4
#define MAPPED_SPACE_BITS   (4*(PAGE_SHIFT - PTE_BITS) + PAGE_SHIFT)
#endif

(but then VMALLOC_END is still "wrong", you still can't easily change
the PTE size...)

This is really tangential to your change however, so probably doesn't
belong in the same changeset.  Maybe I could revive that old patch if
anyone has any comments.
