I have used the second patch of the series for the past two years with
no problems. Without the patch, the reliability of PCI passthrough of the
Intel IGD to a Xen HVM guest is very poor, and in some cases the guest
fails to start without the patch.

Intel specifies that the Intel IGD must occupy slot 2 on the PCI bus,
as noted in docs/igd-assign.txt in the Qemu source code.

This is a series of two patches:
The first fixes FTBFS when --enable-xen and --disable-xen-pci-passthrough
configure options are set with when building for the linux target os.
The second fixes a regression that was introduced many years ago with the

that the vendor be Intel,
because only Intel IGD devices have an Intel OpRegion. These are the
same checks hvmloader and libxl do to determine if the Intel OpRegion
needs to be mapped into the guest's memory.
