David Hildenbrand ea5f496925 KVM: s390: only one external call may be pending at a time ... Only one external call may be pending at a vcpu at a time. For this reason, we have to detect whether the SIGP externcal call interpretation facility is available. If so, all external calls have to be injected using this mechanism. SIGP EXTERNAL CALL orders have to return whether another external call is already pending. This check was missing until now. SIGP SENSE hasn't returned yet in all conditions whether an external call was pending. If a SIGP EXTERNAL CALL irq is to be injected and one is already pending, -EBUSY is returned.
