[S390] dcssblk: add >2G DCSSs support and stacked contiguous DCSSs support.
The DCSS block device driver is modified to add >2G DCSSs support and allow a DCSS block device to map to a set of contiguous DCSSs. The extmem code is also modified to use new Diagnose x'64' subcodes for >2G DCSSs. Signed-off-by: Hongjie Yang <hongjie@us.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
