I asked SO to recount arguments and we've come to a conclusion that
there're in fact 19 args not 18 as the name suggests. 19 args is
I-N-S-A-N-E.

It will be partially cleaned up by:
http://ozlabs.org/pipermail/linuxppc-dev/2006-July/024556.html
However it doesnt fix the fact someone has architected such a crazy
interface :(

well, just as background info, this is the wrapper around
a single assembly instruction which calls system firmware and takes
9 CPU registers for input and 9 CPU registers for output parameters.
This definition by platform architecture won't change in the near future,
but the good news is with Antons change the wrapper will look much nicer.

Returncode handling was reworked throughout the whole driver. Those assignments
were modified according to your suggestion.

Correct. They're returning void now.
