/*
* Xen PCI Frontend Stub - puts some "dummy" functions in to the Linux
* x86 PCI core to support the Xen PCI Frontend
* Xen PCI - handle PCI (INTx) and MSI infrastructure calls for PV, HVM and
* initial domain support. We also handle the DSDT _PRT callbacks for GSI's
* used in HVM and initial domain mode (PV does not parse ACPI, so it has no
* concept of GSIs). Under PV we hook under the pnbbios API for IRQs and
* 0xcf8 PCI configuration read/write.
