MSI badness in xen-unstable
Hi,
I''ve been trying to boot stefano''s minimal dom0 kernel from
git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git
2.6.36-rc1-initial-domain-v2+pat
On xen-unstable, I get the following WARN_ON()''s from Xen when bringing
up the NIC''s, then the machine hangs forever when trying to login either
over serial or NIC.

[V6 PATCH 0/7]: PVH dom0....
Hi,
V6: The only change from V5 is in patch #6:
- changed comment to reflect autoxlate
- removed a redundant ASSERT
- reworked logic a bit so that get_page_from_gfn() is called with NULL
for p2m type as before. arm has ASSERT wanting it to be NULL.
Tim: patch 4 needs your approval.
Daniel: patch 5 needs your approval.
These patches implement PVH dom0.
