Revision 1.9 changes the delivery mode from the magic constant 0
(i.e. fixed delivery) to SAPIC_DELMODE_LOWPRI. While the commit
log doesn't mention the change in behaviour, it is believed to be
deliberate. In the last 5.5 years this hasn't been a problem. Nor
do I think did it make any difference, but who knows. However, I
do know that it break SMP support for Montecito-based machines.
Switch back to fixed-CPU delivery so that SMP works again. This
gives me some time to look more closely at the problem, as well
as make sure the I-cache validation as it's implemented currently
is sufficient in SMP configurations...
