Subject: [PATCH 0/1] Fixing lost and mess up of Kernel messages while
 restarting or shutting down

This change is to fix lost and mess up of Kernel messages while restarting or
shutting down.
If the console lock is held by other CPU running while the system is restarting
or shutting down, the Kernel messages in the printk log buffer can not be
printed out to the console drivers. The Kernel messages can be lost or
messed up.
This change calls console_unlock after SMP stopped to flush the kernel messages
in the printk log buffer to the console drivers.
