The handling of PCI domains (or PCI segments in ACPI speak) is usually a straightforward affair but its implementation is currently left to the architectural code, with pci_domain_nr(b) querying the value of the domain associated with bus b. This patch introduces CONFIG_PCI_DOMAINS_GENERIC as an option that can be selected if an architecture wants a simple implementation where the value of the domain associated with a bus is stored in struct pci_bus. The architectures that select CONFIG_PCI_DOMAINS_GENERIC will then have to implement pci_bus_assign_domain_nr() as a way of setting the domain number associated with a root bus. All child buses except the root bus will inherit the domain_nr value from their parent.
