The last thing we agreed on was to remove the macros entirely for 2.6.19,
on all architectures. Unfortunately, I think nobody actually _did_ that,
so they are still there.

- * shift all parameters down one register to maintain the original
- * order.
- *
- * At best case (zero arguments), we just write the syscall number to
- * a2.  At worst case (1 to 6 arguments), we move the argument in a2
- * to the next available register, then write the syscall number to
