One could say the abilities allowed a powerpc pci_controller is neither subset nor a superset of the abilities of a Freescale PCIe controller. Thankfully, the most useful bits are in the intersection of the two abilities.
That sign issue shouldn't be too hard to fix if there's a real need by making sure everything is unsigned and of the same width, in which case, an addition with the unsigned pci_mem_offset will properly result in a substraction of the later is negative, even when everybody is unsigned :-) But I don't see any pressing need for that.
