From f214be50f317d78c47532d4ca8aa0ba5e79fc1ca Mon Sep 17 00:00:00 2001 From: Zhiwu Song <Zhiwu.Song@csr.com> Date: Wed, 7 May 2014 14:46:44 +0800 Subject: [PATCH] clocksource: marco: Fix the affinity set for local timer of CPU1 irqchip will reject the affinity set to CPUs which is not online yet. but in the CPU1 wakeup stage, OS only sets CPU1 to be online after local timer is set, so that causes the irq_set_affinity not work. this patch moves to irq_force_affinity() for the low level boot stage.
