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.
