[GIT PULL] xen/dom0: core dom0 support

[Jeremy Fitzhardinge]

This series adds core dom0 support for Xen, allowing the kernel to boot
as Xen's control domain.  It isn't much use on its own (it doesn't result
in a booting dom0 kernel), but it lays the foundations for later changes.
Native booting is unaffected.

This is largely unchanged from the last posting, other than being rebased
to a newer version of tip/master (or, more precisely, the other Xen topic
branches which themselves have been rebased).

Thanks,
	J
