I'm ok with returning 0 from s390's kvm_arch_vcpu_should_kick() until we sort out architecture-specific kicks. Adding kvm_vcpu_wake_up() in [6/6] is the reason why the other patches were included. Compile tested on s390, lightly tested and checked that kvm_*_request() uses are being optimized on x86.
