[PATCH] suspend-to-{RAM,disk}
Here's suspend-to-{RAM,disk} combined patch for
2.5.17. Suspend-to-disk is pretty stable and was tested in
2.4-ac. Suspend-to-RAM is little more experimental, but works for me,
and is certainly better than disk-eating version currently in kernel.
Major parts are: process stopper, S3 specific code, S4 specific
code.
