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.
