Indeed so - I just sent u one hunk to give an idea. There's other code too where
CONFIG_SMP will be replaced by CONFIG_ISS_SMP_EXTN as I'm decoupling SMP support
from this SMP extension.

I'll push a patch later today - which will hopefully hit mainline within this
merge window - if not in one of the rcs.
