Subject: [PATCH 8/9] pc-bios/s390x: Initialize machine loadparm before probing
IPL devices
RH-Author: Thomas Huth <thuth@redhat.com>
RH-MergeRequest: 297: [c10s] Fixes for the new s390x "boot order" feature
RH-Jira: RHEL-68444
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
RH-Commit: [7/8] 7513fec6ef170ab0c2068a7641a79b77537f1608 (thuth/qemu-kvm-cs9)
Commit bb185de423 ("s390x: Add individual loadparm assignment to
CCW device") allowed boot devices to be assigned a loadparm value independent
of the machine value, however, when no boot devices are defined, the machine
loadparm becomes ignored. Therefore, let's check the machine loadparm
prior to probing the devices.
