| 13 | * Just any arbitrary offset to the start of the vmalloc VM area: the |
| 14 | * current 8MB value just means that there will be a 8MB "hole" after the |
| 15 | * physical memory until the kernel virtual memory starts. That means that |
| 16 | * any out-of-bounds memory accesses will hopefully be caught. |
| 17 | * The vmalloc() routines leaves a hole of 4kB between each vmalloced |
| 18 | * area for the same reason. ;) |
