This moves the xen_modified_memory call from cpu_physical_memory_map to cpu_physical_memory_unmap because the memory could be migrated before the device model have written to it. But because we need to know the guest address and to avoid rewriting a new function, the call is moved to qemu_invalidate_entry. So this later has to new parameters, the length of the mapping and if it was a write.

Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very
