[RFC] Genirq and CPU isolation

2008-02-22 Thread Max Krasnyansky
Hi Thomas, While reviewing CPU isolation patches Peter pointed out that instead of changing arch specific irq handling I should be extending genirq code. Which makes perfect sense. Why didn't I think of that before :) Basically the idea is that by default isolated CPUs must not get HW irqs routed
