| bool "Check for stack overflows" |

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

| config DEBUG_STACK_USAGE |
| bool "Stack utilization instrumentation" |
| depends on DEBUG_KERNEL |
| help |
| Enables the display of the minimum amount of free stack which each |
| task has ever had available in the sysrq-T and sysrq-P debug output. |

| This option will slow down process creation somewhat. |

| config DEBUG_PAGEALLOC |

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

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