PATCH 1/1 s390 c/r: fix up v14 (v2)

Uh, discard the previous version :)

Make a few changes to the s390 c/r code to reflect v14 changes. CONFIG_CHECKPOINT_RESTART is now CONFIG_CHECKPOINT, and 'parent' is gone.

Compiler missed another use of parent. This version actually is tested with a working c/r :)
