From 1417836e81c0ab8f5a0bfeafa90d3eaa41b2a067 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Tue, 14 Nov 2006 01:13:18 +0900 Subject: [MIPS] use generic_handle_irq, handle_level_irq, handle_percpu_irq 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.
