    The first entry (devices/pci2/....) is wrong imho.

    With multiple domains, we can have several busses with the same bus number,
    one in each domain. So it's a matter of taking the current set of pciN
    entries and moving them below a "pci-domain" entry (or hose, or whatever
    Linus prefers).

    Also, the node name for individual PCI devices must include the domain
    number, the current bus:dev.fn notation isn't enough, that will break
    things like /sys/bus/pci/devices when you have several identical bus/devfn
    pairs on different domains
