From b1cffebf1029c87e1f1984d48463ee21093a6bc7 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Mon, 26 Nov 2012 15:05:48 -0600 Subject: ARM: GIC: remove direct use of gic_raise_softirq In preparation of moving gic code to drivers/irqchip, remove the direct platform dependencies on gic_raise_softirq. Move the setup of smp_cross_call into the gic code and use arch_send_wakeup_ipi_mask function to trigger wake-up IPIs.
