From: Suzuki K Poulose <suzuki.poulose@arm.com> commit fce6361fe9b0caeba0c05b7d72ceda406f8780df upstream. This patch moves cpu_die_early to smp.c, where it fits better. No functional changes, except for adding the necessary checks for CONFIG_HOTPLUG_CPU.

Done, thanks. -- viresh _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
