Subject: [S390] Replace nopav-message on VM.

From: Peter Oberparleiter <[email protected]>

[S390] Replace nopav-message on VM.

Specifying kernel parameter "dasd=nopav" on systems running under VM
has no function but results in message "disable PAV mode". Correct
message is "'nopav' not supported on VM".
