This is an overly simplified view of things. There exist syscalls where it's not just a matter of padding, but instead where the chosen argument order interacts with the ABI padding requirements to produce something which the syscall interface can't handle. There are two solutions to that: reorder the syscall arguments or split them up into 32-bit high/low quantities.
I just went back and looked specifically at this, and I wonder if you could be more concrete. In particular, this seems to imply a rule somewhere which could probably be improved reasonably easily.
