  s390: Fix cpu shutdown for KVM
  s390: fix short kernel command lines
  s390: fix reset hypercall to reset the status
  s390x: implement SIGP restart and shutdown
  s390x: implement rrbe instruction properly
  s390x: update R and C bits in storage key
  s390x: make ipte 31-bit aware
  s390x: add ldeb instruction
