From mboxrd@z Thu Jan 1 00:00:00 1970 From: 21cnbao@gmail.com (Barry Song) Date: Wed, 7 May 2014 14:46:44 +0800 Subject: [PATCH] clocksource: marco: fix the affinity set for local timer of CPU1 Message-ID: <1399445204-22159-1-git-send-email-21cnbao@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Zhiwu Song 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.
