Dual CPU MTX first boot

Fri Jan 22 18:58:18 EST 1999

Just to let you all know, I have managed to boot an MTX board with both
CPU's. This is 2.2.0-pre7, with my integrated version of Gabriel Paubert's
and Corey Minyard's patches.

Also, to start SMP, I have to access the residual data. Right now I've got
an ugly hack that does it in the bootloader, which sets MSR[IP] to zero,
then I use the OpenPIC to reset the CPU.

What would it take to map in the residual data so this could be cleaner
(and save a couple of uneeded copies of it also..)

(There is a problem with kswapd though.. ;)
