Note: This patch can be applied after the patch titled: "[PATCH] mips irq cleanups" in lmo linux-queue tree (or 2.6.19-rc5-mm1) and the patch titled: "[PATCH] do_IRQ cleanup" (http://www.linux-mips.org/archives/linux-mips/2006-10/msg00348.html) Further incorporation of generic irq framework. Replacing __do_IRQ() by proper flow handler would make the irq handling path a bit simpler and faster. * use generic_handle_irq() instead of __do_IRQ(). * use handle_level_irq for obvious level-type irq chips. * use handle_percpu_irq for irqs marked as IRQ_PER_CPU. * setup .eoi routine for irq chips possibly used with handle_percpu_irq.
