| 16 | Unmap pages from the kernel linear mapping after free_pages(). |
| 17 | This results in a large slowdown, but helps to find certain types |

| 23 | If you say Y here the resulting kernel image will be slightly larger |
| 24 | and slower, but it will give very useful debugging information. |
| 25 | If you don't debug the kernel, you can say N, but we may not be able |
| 26 | to solve problems without frame pointers. |
