10 drops below a certain limit.

16 Enables the display of the minimum amount of free stack which each

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.

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.
