| 19 | * | ||
| 20 | * This structure was historically called systemcfg and exposed to | ||
| 21 | * userland via /proc/ppc64/systemcfg. Unfortunately, this became an | ||
| 22 | * ABI issue as some proprietary software started relying on being able | ||
| 23 | * to mmap() it, thus we have to keep the base layout at least for a | ||
| 24 | * few kernel versions. | ||
| 25 | * | ||
| 26 | * However, since ppc32 doesn't suffer from this backward handicap, | ||
| 27 | * a simpler version of the data structure is used there with only the | ||
| 28 | * fields actually used by the vDSO. | ||
