Merge tag 'kvm-s390-master-4.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux
KVM: s390: Fixes
- Fix random memory corruption when running as guest2 (e.g. KVM in
LPAR) and starting guest3 (nested KVM) with many CPUs (e.g. a nested
guest with 200 vcpu)
- io interrupt delivery counter was not exported
