+ This option tells the compiler NOT to build the code under
+ arch/powerpc with the -Werror flag (which means warnings
+ are treated as errors).

+ This option allows you to set the stack depth that the kernel
+ prints in stack traces. This can be useful if your display is
+ too small and stack traces cause important information to
+ scroll off the screen.

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.
