* remotes/cohuck/tags/s390x-20141010:
  s390x/virtio-ccw: fix vhost-scsi intialization
  s390x/migration: migrate CPU state
  s390x/kvm: synchronize the cpu state after SIGP (INITIAL) CPU RESET
  s390x/kvm: reuse kvm_s390_reset_vcpu() to get rid of ifdefs
  s390x/kvm: propagate s390 cpu state to kvm
  s390x/kvm: proper use of the cpu states OPERATING and STOPPED
  s390x/kvm: introduce proper states for s390 cpus
  linux-headers: update to 3.17-rc7
