    KVM: s390: Fix RUNNING flag misinterpretation · 9e6dabef
    Cornelia Huck authored
    CPUSTAT_RUNNING was implemented signifying that a vcpu is not stopped.
    This is not, however, what the architecture says: RUNNING should be
    set when the host is acting on the behalf of the guest operating
    system.
    
    CPUSTAT_RUNNING has been changed to be set in kvm_arch_vcpu_load()
    and to be unset in kvm_arch_vcpu_put().
    
    For signifying stopped state of a vcpu, a host-controlled bit has
    been used and is set/unset basically on the reverse as the old
    CPUSTAT_RUNNING bit (including pushing it down into stop handling
    proper in handle_stop()).
