Date: Mon, 21 May 2012 14:00:05 +0800 From: Yong Zhang <yong.zhang0@...il.com> To: linux-mips@...ux-mips.org, linux-kernel@...r.kernel.org Cc: ralf@...ux-mips.org, sshtylyov@...sta.com, david.daney@...ium.com Subject: [PATCH 5/8] MIPS: call ->smp_finish() a little late From: Yong Zhang <yong.zhang@...driver.com> We have move irq enable to ->smp_finish. Place ->smp_finish() a little late to prepare for move set_cpu_online() into start_secondary. And it's not necessary to call cpu_set(cpu, cpu_callin_map) and synchronise_count_slave() with irq enabled.
