From: Cedric Le Goater <clg@fr.ibm.com>

This patch is the first step in making the refrigerator() available 
to all architectures, even for those without power management. 

The purpose of such a change is to be able to use the refrigerator() 
in a new container subsystem which will implement a container freezer.

The TIF_FREEZE value should be checked by each arch MAINTAINER.
