[Qemu-devel] [PATCH for-2.7 5/9] s390x/ipl: Provide ipl parameter block |
Date: |

From: Alexander Yarygin <address@hidden>
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.
