[PATCH 5/8] MIPS: call ->smp_finish() a little late

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yong Zhang <yong.zhang@xxxxxxxxxxxxx>

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.
