Can you make a patch to clean this up too? The right parts of it need
to get moved to the uapi header and it should work similarly to the
ib_uverbs_wr_opcode / ib_wr_opcode thing.

You'll also need to do something about the 32 bit compatability that
kbuild detected - I suppose this can't work on 32 bit platforms? So
IS_ENABLED() it off or something?
