config DEBUG_PAGEALLOC
	bool "Debug page memory allocations"
	depends on DEBUG_KERNEL && BROKEN
	help
	  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.
