RE: Xen and the Art of Linux/ia64 Virtualization

From: Magenheimer, Dan (HP Labs Fort Collins) <dan.magenheimer_at_hp.com>

Revision 4.  Minor formatting change suggested by
Christoph.  Also, no change for "symmetry" suggested
by Christoph as Tony wanted to leave as is. 

Tony I think this is now ready to apply.  If there is
anything else needed, please let me know.

Thanks,
Dan Magenheimer
