Subject: [PATCH v3] KVM: remove #ifndef CONFIG_S390 around kvm_vcpu_wake_up

The #ifndef was protecting a missing halt_wakeup stat, but that is no
longer necessary.  The #ifndef around kvm_vcpu_kick is still necessary
as s390 does not export smp_send_reschedule.

 v3: kept kvm_vcpu_kick() under the #ifndef and compile tested with kvm
     configured as module too ...
