917 | * The system reset requirements are driven by existing Linux and PowerVM | |

921 | * does not look at the error value). | |
922 | * | |
923 | * System reset interrupts are not subject to interlock like machine | |
924 | * check, so this memory area could be corrupted if the sreset is | |
925 | * interrupted by a machine check (or vice versa) if it was shared. To | |
926 | * prevent this, system reset uses per-CPU areas for the sreset save | |
927 | * area. A system reset that interrupts a system reset handler could | |
928 | * still overwrite this area, but Linux doesn't try to recover in that | |
929 | * case anyway. | |

1897 | * As such, we can avoid migrating the CAS-negotiated options if these | |
1898 | * are the only options available on the current machine/platform. | |
1899 | * Since these are the only options available for pseries-2.7 and | |

1901 | * compatibility. | |

1903 | * For QEMU 2.8+, there are additional CAS-negotiatable options available | |
