[PATCH 00 of 38] xen: add more Xen dom0 support
Hi Ingo,
Here''s the chunk of patches to add Xen Dom0 support (it''s probably
worth creating a new xen/dom0 topic branch for it).
A dom0 Xen domain is basically the same as a normal domU domain, but
it has extra privileges to directly access hardware. There are two
issues to deal with:
- translating to and from the domain''s pseudo-physical addresses and
real machine
