config DEBUG_STACKOVERFLOW

        bool "Check for stack overflows"

        depends on DEBUG_KERNEL

        help

          This option will cause messages to be printed if free stack space

          drops below a certain limit.

config DEBUG_STACK_USAGE

        bool "Stack utilization instrumentation"

        depends on DEBUG_KERNEL

        help

          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.

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.
