Subject: [S390] Replace nopav-message on VM.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dcd707b4bdc10b4fa20efa116dbaeded21513115;p=linux-beck.git

[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".
