The commit 5dfc54e087c15f823ee9b6541d2f0f314e69cbed
("ARM: GIC: avoid routing interrupts to offline CPUs")
prevents routing interrupts to offline CPUs. But in
case of timer on EXYNOS4, the irq_set_affinity() method
is called in percpu_timer_setup() before CPU1 becomes
online. So this patch fixes routing timer interrupt to
offline CPU.Reported-by: Changhwan Youn <[email protected]> Signed-off-by: Kukjin Kim <[email protected]> --- Hi Russell and all, I'm not sure it's safe to call set_cpu_online() here... arch/arm/mach-exynos4/platsmp.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-) diff --git a/arch/arm/mach-exynos4/platsmp.c b/arch/arm/mach-exynos4/platsmp.c index 96cc651..a3346e3 100644 --- a/arch/arm/mach-exynos4/platsmp.c +++ b/arch/arm/mach-exynos4/platsmp.c @@ -109,6 +109,8 @@ void __cpuinit platform_secondary_init(unsigned int cpu) */ spin_lock(&boot_lock); spin_unlock(&boot_lock); + + set_cpu_online(cpu, true); } int __cpuinit boot_secondary(unsigned int cpu, struct task_struct *idle) -- 1.7.1 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
