| 409 | * match the expected length. In other words, the length of the |
| 410 | * FADT is the bottom line as to what the version really is. |

| 413 | * version was used only for prototyping and testing during the |
| 414 | * 32-bit to 64-bit transition. V3 was the first official 64-bit |
| 415 | * version of the FADT. |
| 416 | * |
| 417 | * Update this list of defines when a new version of the FADT is |
| 418 | * added to the ACPI specification. Note that the FADT version is |
| 419 | * only incremented when new fields are appended to the existing |
| 420 | * version. Therefore, the FADT version is competely independent |
