| Unmap pages from the kernel linear mapping after free_pages(). |

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