[PATCH] PCI: NUMA-Q PCI config access arg validation
Fix NUMA-Q PCI config access bus validation. "bus" indexes
into BUS2QUAD, which is mp_bus_id_to_node[MAX_MP_BUSSES].
This depends on the "pci_raw_ops should use unsigned args"
patch I posted earlier today (no functional dependency; it
just happens to be very close textually).
