From 292b293ceef2eda1f96f0c90b96e954d7bdabd1c Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Wed, 20 Jul 2011 16:24:14 +0100 Subject: ARM: gic: consolidate PPI handling PPI handling is a bit of an odd beast. It uses its own low level handling code and is hardwired to the local timers (hence lacking a registration interface). Instead, switch the low handling to the normal SPI handling code. PPIs are handled by the handle_percpu_devid_irq flow. This also allows the removal of some duplicated code.
