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.

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.
