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.
