| 111 | |
| 112 | For example, based on what ACPI exports as the supported revision, |

| 121 | ACPI revision via the "acpi_rev_override" command line switch. |

| 486 | Certain usages such as Predictive Failure Analysis (PFA) require |
| 487 | more information about the error than what can be described in |
| 488 | processor machine check banks. Most server processors log |
| 489 | additional information about the error in processor uncore |
| 490 | registers. Since the addresses and layout of these registers vary |
| 491 | widely from one processor to another, system software cannot |
| 492 | readily make use of them. To complicate matters further, some of |
| 493 | the additional error information cannot be constructed without |
| 494 | detailed knowledge about platform topology. |
