no problem - I've done worse.

Why not? I added it because I didn't like assumption the caller
to *io_pdir_entry was passing KERNEL_SPACE argument. If that's going
to forever be true, then we may as well hardcode KERNEL_SPACE
in both ccio and sba io_pdir_entry() routines instead of
taking a space_id parameter. Would save us a few cycles.

That's what it looked like to me too.
It now uses %r0.

Like I said, this isn't a problem that bothers me.
thanks!
