Subject: [PATCH v5 1/4] PCI: Export symbols of PCI functions

Export symbols of the following PCI functions so they can be referenced
by a PCI driver compiled as a kernel loadable module:

pci_common_swizzle
pci_create_root_bus
pci_stop_root_bus
pci_remove_root_bus
pci_assign_unassigned_bus_resources
pci_fixup_irqs
