From 6aed958978ba9e32301b131e1c5dcadcf952a1ed Mon Sep 17 00:00:00 2001 From: Alexander Yarygin Date: Tue, 21 Jul 2015 14:10:39 +0300 Subject: [PATCH] s390x/ipl: Provide ipl parameter block Right now we return the ipl parameter block only if the guest specified one. Let's fill in the parameter block when bootindex parameter is available and not booting from an external kernel.
