    KVM: s390: Inject machine check into the guest · 4d62fcc0
    QingFeng Hao 提交于
    If the exit flag of SIE indicates that a machine check has happened
    during guest's running and needs to be injected, inject it to the guest
    accordingly.
    But some machine checks, e.g. Channel Report Pending (CRW), refer to
    host conditions only (the guest's channel devices are not managed by
    the kernel directly) and are therefore not injected into the guest.
    External Damage (ED) is also not reinjected into the guest because ETR
    conditions are gone in Linux and STP conditions are not enabled in the
    guest, and ED contains only these 8 ETR and STP conditions.
    In general, instruction-processing damage, system recovery,
    storage error, service-processor damage and channel subsystem damage
    will be reinjected into the guest, and the remain (System damage,
    timing-facility damage, warning, ED and CRW) will be handled on the host.
