Yes, the byteswapping stuff (CONFIG_SWAP_IO_SPACE) also got lost.

Not as is - the kernel has changed, so your patch wouldn't apply anymore.
Aside of that I don't think we'll have any alternative to do something
along the lines of your patch. There are for example systems where the
high 8 bits of the I/O or memory address on the ISA bus are supplied in
a separate register of the chipset, not as part of the memory address
itself. It's really remarkable how much bad taste some hardware designers
