- 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.

- 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.
