[patch 05/18] metag: Adjust system_state check
From: Thomas Gleixner
Date: Sun May 14 2017 - 14:39:36 EST
To enable smp_processor_id() and might_sleep() debug checks earlier, it's
required to add system states between SYSTEM_BOOTING and SYSTEM_RUNNING.
Adjust the system_state check in stop_this_cpu() to handle the extra states.
