The PCI MMCONFIG area is usually reserved via the E820 so the Xen hypervisor is aware of these regions. But they can also be enumerated in the ACPI DSDT which means the hypervisor won't know of them until the initial domain informs it of via PHYSDEVOP_pci_mmcfg_reserved. This is what this patch does for all of the MCFG regions that the initial domain is aware of (E820 enumerated and ACPI).
