various s390x updates:
- cpu state handling in qemu and migration
- vhost-scsi-ccw bugfix

# gpg: Signature made Fri 10 Oct 2014 14:01:34 BST using RSA key ID C6F02FAF
# gpg: Can't check signature: public key not found

* 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
