From 57f27cca7ab59cec05adc85cef97e9b4f7d28d78 Mon Sep 17 00:00:00 2001 From: "Srivatsa S. Bhat" Date: Thu, 22 Mar 2012 16:58:25 +0530 Subject: hexagon/CPU hotplug: Add missing call to notify_cpu_starting() The scheduler depends on receiving the CPU_STARTING notification, without which we end up into a lot of trouble. So add the missing call to notify_cpu_starting() in the bringup code. Signed-off-by: Srivatsa S.
