there's at least three problems here :-)
1. do we want to do SMP of any kind in CAR? I think not, but I'd like
to hear Marc's opinion
2. There are techniques from the oldest days of PCI (cf8/cfc) that we
use that don't work well in a multicore world.
MMCONF, it seems, can help here. Using MMCONF for config cycles
may only work for newer CPUs,
but we really ought to move to something that doesn't require a
shared resource such as cf8/cfc for more modern
CPUs.
3. we need smp style locking code for printk.
Any more :-)
