this patch set implements hibernation support for s390. All s390
specific buses grow pm callbacks and all the s390 device drivers
are modified to make use of the callbacks. This allows to do

echo disk > /sys/power/state

to save the state of the running linux image to swap. A normal
ipl (alias boot) of the same kernel will detect the stored image
on swap and resume the save image. Works for guests under z/VM
and for LPARs.

The patches are meant to be applied on top of the s390 tree found
	git:// features

Have fun..
