Re: [PATCH] PPC: PCI: Fix pcibios_io_space_offset() so it works for 32-bit ptr/64-bit rsrcs

Without the fix that I sent, it ends up looking like:

pci_bus 0000:00: root bus resource [io  0xffbed000-0xffbfcfff] (bus
address [0x0000-0xffff])

And that's when some devices fail to be assigned valid bar 0's and the
kernel complains because of it.

Note that oddly, the second range of bus addresses looks -more- correct
than the first one...

Cheers,
