^~~~~~~~~~~~~ I originally ran into this last year when the patches were part of linux-next, and tried to work around it by using the proper 'pteval_t' types consistently, but that caused additional problems. This takes a much simpler approach, and makes the argument type of the dummy helper always 64-bit, which is wide enough for any page table layout and won't hurt since this call is just an empty stub anyway.
