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. |

24 | help |
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. |

29 | config FRAME_POINTER |
30 | bool "Compile the kernel with frame pointers" |
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. |
