From d1640130cda146ed925f12434bfe579ee7d80a1c Mon Sep 17 00:00:00 2001 From: "Srivatsa S. Bhat" Date: Thu, 22 Mar 2012 16:59:11 +0530 Subject: tile/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.

Extend the #ifdef to cover all the code and data for now.
