Yes, a particular adaptor as identified by an OF pathname.  The
linux,pci-domain property was added because without it, it wasn't
possible to determine reliably the correspondence between OF pathnames
and Linux device names.

Now that we have the devspec entry in sysfs it's possible that we
don't need the linux,pci-domain property.  I'll talk to Martin about
it on Monday.
