I don't see that PPC is converted to genirq, that new API. And I'm not
sure (while not being a PPC expert) if it ever will be, specifically as
PowerPC is already on genirq and should obsolete PPC one day, right?

Anyway, there is an unreleased work-in-progress patch for x86 over -rc6
by Philippe. I recently had the chance to test it and hack a bit on the
SMP IO-APIC part. It seems to work fine under UP, but SMP had some
issues that are identified, but still need to be addressed - thanks to
genirq, now in a widely arch-independent way.

Philippe, I know you are very busy, but shouldn't we make a pre-release
available already, also to discuss further how to deal best with genirq
on other platforms beyond x86?
