| 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. | |
