Thanks for posting this, it fixes quite some issues in the posted IRQ
implemention. I skimmed through the AMD IOMMU changes and besides some
small things didn't spot anything worrisome.

Adding Suravee and Vasant from AMD to this thread for deeper review
(also of the KVM parts) and testing.

Thanks,
