here is the first s390 pull request for 4.5. It also contains the
remaining vcpu lookup changes and an improved cleanup of the kvm_stat
exit path.
I have deferred the kvm_stat per VM patches.

The s390 changes are:
- ESCA support (up to 248 CPUs)
- detection if KVM works (e.g. for nested virtualization)
- cleanups

The following changes since commit bb11c6c96544737aede6a2eb92e5c6bc8b46534b:

  KVM: x86: MMU: Remove unused parameter parent_pte from kvm_mmu_get_page()

  KVM: s390: remove redudant assigment of error code (2015-11-30 12:47:13 +0100)

KVM: s390 features, kvm_get_vcpu_by_id and stat

Several features for s390
1. ESCA support (up to 248 vCPUs)
2. KVM detection: we  can now detect if we support KVM (e.g. does KVM
   under KVM work?)

1. cleanup

1. Use kvm_get_vcpu_by_id where appropriate
2. Apply a heuristic to optimize for ID VCPU == No. VCPU
