Subject: KVM: s390: Zero out current VMDB of STSI before including level3 data.
From: Ekaterina Tumanova <tumanova@xxxxxxxxxxxxxxxxxx>
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.
