I don't have an objection to this patch series even it may mean I have
to do some additional fixups.

But I did want to point out a misapprehension in Glauber Costa's
comments.  The qemu-xen tree does not use the TCG parts of qemu at
all; we don't even compile them in.  We provide our own implementation
of cpu_physical_memory_rw and so on.
