Merge tag 'kvm-s390-next-4.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into HEAD
KVM: s390: fixes and features - more kvm stat counters - virtio gpu plumbing. The 3 non-KVM/s390 patches have Acks from Bartlomiej Zolnierkiewicz, Heiko Carstens and Greg Kroah-Hartman but all belong together to make virtio-gpu work as a tty. So I carried them in the KVM/s390 tree. - document some KVM_CAPs - cpu-model only facilities - cleanups

This capability indicates if the flic device will be able to get/set the
AIS states for migration via the KVM_DEV_FLIC_AISM_ALL attribute and allows
to discover this without having to create a flic device.
