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.

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.

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.
