I have to check what the new, fully implemented genirq does. But I realized, that the common IRQ structure is used now (resulting in some name changes, w.g. ->handler ->chip). Likely, PPC and PowerPC already use the new genirq. > Anyway, there is an unreleased work-in-progress patch for x86 over -rc6 > by Philippe.
