erm, i mean, actually i do:

#define IOMEM_PCIPROXY (5 << IO_MEM_SHIFT)

cpu_register_io_memory(IOMEM_PCIPROXY >> IO_MEM_SHIFT,
                       pciproxy_readl,
                       pciproxy_writel);

cpu_register_phys_mem(addr, len, IOMEM_PCIPROXY);

And can i still make the change to cpu_register_io_memory to pass down
an opaque pointer? Actually this would be nicer on the
cpu_register_phys_mem, but that'd be an impact on hot-paths i guess so
I'll just have to work around it in pciproxy.
