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

| 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. | |
