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

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. | |
