| 9 | This option will cause messages to be printed if free stack space | |
| 10 | drops below a certain limit. | |

| 16 | Enables the display of the minimum amount of free stack which each | |
| 17 | task has ever had available in the sysrq-T and sysrq-P debug output. | |

| 19 | This option will slow down process creation somewhat. | |

| 25 | Unmap pages from the kernel linear mapping after free_pages(). | |
| 26 | This results in a large slowdown, but helps to find certain types | |
| 27 | of memory corruptions. | |

| 31 | help | |
| 32 | If you say Y here the resulting kernel image will be slightly larger | |
| 33 | and slower, but it will give very useful debugging information. | |
| 34 | If you don't debug the kernel, you can say N, but we may not be able | |
| 35 | to solve problems without frame pointers. | |
