Merge remote-tracking branch 'remotes/borntraeger/tags/kvm-s390-20140131' into staging

This patch set contains the sclp defines and events for cpu hotplug,
the initial sclp defines (without code yet) for standby memory (some
sort of memory hotplug) as well as a cleanup of the kvm register
synchronization.
