Subject: [PATCH 3/4] s390-tools-1.8.1-zipl-kdump-man
Description: Add kdump kernel installation instruction to zipl man page.
Symptom: User wants to prepare SCSI disk for dump, but has not installed
the kdump kernel rpm.
Problem: The installation of the kdump kernel rpm is prereq for preparing
a SCSI dump disk for dump.
Solution: Document that in the zipl man page.

Subject: [PATCH 4/4] Support for new storage device on System z (rhbz#847086)
Allow Linux to access a new storage device as a block device using a new interface.
That includes the adaption of common IO functions to allow to attach, configure
and operate the new subchannels.
