  s390x/mmu: don't overwrite pending exception in mmu translate
  vfio-ccw: fix memory leaks in vfio_ccw_realize()
  pc-bios/s390: update images
  s390: Do not pass inofficial IPL type to the guest
  s390: Ensure IPL from SCSI works as expected
  s390: Refactor IPL parameter block generation
  s390x/kvm: call cpu_synchronize_state() on every kvm_arch_handle_exit()
