From 38db3faa86115d76cc9df29b3706cb90d6583a77 Mon Sep 17 00:00:00 2001 From: Ekaterina Tumanova Date: Tue, 3 Mar 2015 09:54:41 +0100 Subject: KVM: s390: Zero out current VMDB of STSI before including level3 data. commit b75f4c9afac2604feb971441116c07a24ecca1ec upstream. s390 documentation requires words 0 and 10-15 to be reserved and stored as zeros. As we fill out all other fields, we can memset the full structure.
