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

[Serge E. Hallyn]

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  :)
