Maybe I'm stating something which is obvious to everybody, but note
that pci_assign_unassigned_resources is only called from

./arch/alpha/kernel/pci.c: pci_assign_unassigned_resources();
./arch/mips/ddb5074/pci.c: pci_assign_unassigned_resources();
./arch/arm/kernel/bios32.c: pci_assign_unassigned_resources();

so it looks like most archs don't use it anyway. (And that's supposedly
why pci_set_master helped people on x86)
