[IA64] pcibus_to_node implementation for IA64
pcibus_to_node provides a way for the Linux kernel to identify to which node a certain pcibus connects to. Allocations of control structures for devices can then be made on the node where the pci bus is located to allow local access during interrupt and other device manipulation. This patch provides a new "node" field in the the pci_controller structure. The node field will be set based on ACPI information (thanks to Alex Williamson <alex.williamson@hp.com for that piece).
