parent[PARISC] Fix uniprocessor build by dummying smp_send_all_nop() (diff)
[PARISC] Add IRQ affinities
This really only adds them for the machines I can check SMP on, which is CPU interrupts and IOSAPIC (so not any of the GSC based machines). With this patch, irqbalanced can be used to maintain irq balancing. Unfortunately, irqbalanced is a bit x86 centric, so it doesn't do an incredibly good job, but it does work.
