[GIT PULL] some core Xen updates

[Jeremy Fitzhardinge <jeremy@goop.org>]

Hi Ingo,

Here's some core Xen changes: bug fixes, debuggability improvements and cleanups.
These are based on tip/x86/xen, but I've merged in tip/master to bring it up to date
before adding my changes.

BTW, I killed off all the jsgf/* branches in xen.git, but I think you've either
already picked up all the push requests, or I'll resend anything missing.

Thanks,
	J
