Hi all,
Accidentally added v2 tag. Please ignore it, this is version 1.

This series provides few bug fixes for emulated AMD IOMMU. The series is based
on top of qemu upstream master commit d922088eb4ba.
Patch 1: The code was using wrong DTE field to determine interrupt passthrough.
Hence replaced it with correct field according to [1].
Patch 2: Current code sets the PCI capability BAR low and high to the
lower and upper 16 bits of AMDVI_BASE_ADDR respectively, which is
wrong. Instead use 32 bit mask to set the PCI capability BAR low and
high.
The guest IOMMU driver works with current qemu code because it uses
base address from the IVRS table and not the one provided by
PCI capability.
