[Xen-devel] [PATCH] amd iommu: re-enable iommu msi if dom0 disabled it

[Wei Wang <wei.wang2@xxxxxxx>]

Hi Jan,
I found that recent dom0 (e.g 3.4 pv_ops) disables iommu msi capability 
for some reasons and iommu cannot generate any interrupts in this case.
Attached patch re-enables it in device assignment.

Thanks,
Wei
