The kernel uses it (pcpu_running()) to decide whether - To send an emergency call or an external call (external calls are faster when the CPU is already running - e.g., SIE HW assist) - In arch_vcpu_is_preempted(), for an heuristic So nothing actually breaks (as I explained, only used for performance optimizations) -- Thanks, David / dhildenb
