From ac61d143ffe2a6db4d4bcf47c21a5159d6a1b644 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 6 Dec 2010 10:38:14 +0000 Subject: ARM: GIC: move enablement of PPI interrupts to gic.c Avoid adding nasty genirq-specific code to local timers to enable PPI interrupts. Instead, provide a gic function to do this.
