pci_bus_add_devices - insert newly discovered PCI devices : bus to check for new devices
Add newly discovered PCI devices (which are on the bus->devices list) to the global PCI device list, add the sysfs and procfs entries. Where a bridge is found, add the discovered bus to the parents list of child buses, and recurse (breadth-first to be compatible with 2.4)
Call hotplug for each new devices.

pci_bus_alloc_resource - allocate a resource from a parent bus : PCI bus : resource to allocate : size of resource to allocate : alignment of resource to allocate : minimum /proc/iomem address to allocate : IORESOURCE_* type flags : resource alignment function : data argument for resource alignment function
Given the PCI bus a device resides on, the size, minimum address, alignment and type, try to find an acceptable resource allocation for a specific device resource.
pci_walk_bus - walk devices on/under bus, calling callback. bus whose devices should be walked callback to be called for each device found arbitrary pointer to be passed to callback.
Walk the given bus, including any bridged devices on buses under this bus. Call the provided callback on each device found.
We check the return of each time. If it returns anything other than 0, we break out.
