I very much appreciate the removal of the _syscallX macros.  FWIW, the
ia64 version of these macros never worked in userspace anyway.

The m68k changes look ok.

I wouldn't mind putting it into 2.4.

While it may break things in userspace it will hopefully ensure correctness
for userspace, so better kill 'em now than later.  _syscallX() has a too
long history of causing problems.
