From: Cedric Le Goater <clg@xxxxxxxxxx> 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.
