bool "Debug page memory allocations"
depends on DEBUG_KERNEL && BROKEN
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.
bool "Compile the kernel with frame pointers"
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.
