Yeah, and it's ugly for the kernel proper, so that bit is a no-brainer. It's just a matter of hammering out the details.

It doesn't sound from the above that you have any opinion either way about reusing the initial page tables or creating a new set, as long as they're in the same format.

Right.

Xen provides a initial set of pagetables in the appropriate format, so what head.S generates is moot. For simplicity I graft the Xen-provided pagetables into swapper_pg_dir in xen_start_kernel, so it is the functional equivalent to the head.S pagetable construction.

We also don't (yet) support PSE, so that's a non-issue for us too.
