The patch just fixes pci_iomap to use resource_size_t, which fixes bugs with MMIO addresses/size being cropped. It doesn't fix some limitations we still, I think, have in the PCI code with 64 bits BARs on 32 bits platforms (that we could, in fact, probably remove when resource_size_t is 64 bits but we haven't done it yet, at least as far as I remember).
