[PATCH] s390: cio non-unique path group ids
From: Peter Oberparleiter <peter.oberparleiter@de.ibm.com>
The path grouping can fail due to non-unique pathgroup-IDs. The source for
the CPU-ID part of the ID was incorrectly specified on 64 bit systems.
Additionally, the length of the ID was too large due to incorrect data packing
declaration. Fix CPU-ID lowcore address and add missing packing declaration.
