So it's a bit of rmap in there. I'd have to compare with a 2.4
profile and fiddle a few kernel parameters. But I'm not sure
that munmap of extremely sparsely populated pagtetables is very
interesting?

Another issue is that x86 doesn't use a pagetable cache. I think it
got killed from x86 when the pagetables in highmem went in.

This is all from memory.
