Re: [Xen-devel] [RESEND] Question about recursive mappings

I've never come across non-root pagetable linear mappings other than in
the crock that is PAE (3 level) where you have to use 4 entries in an L2
to point to all the L2s due to the limited address space.

And that's something we don't currently support. A slightly more generic linear pagetable logic that would permit us to support linear pagetables on PAE would be a good thing.
