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

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

21 | help | |
22 | Unmap pages from the kernel linear mapping after free_pages(). | |
23 | This results in a large slowdown, but helps to find certain types | |
24 | of memory corruptions. | |

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