I've found the right set of constants and argument parameters.
Those are now committed to include/asm-parisc/pdc.h.

I just realized the comments are incomplete...I only
included ARG0-ARG5 - there can be 8 args depending on
the call...hmm...I'll omit and document in the code
where it's used.

thanks,
