config DEBUG_STACK_USAGE
	bool "Enable 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 KPROBES
	bool "Kprobes"
	depends on DEBUG_KERNEL
	help
	  Kprobes allows you to trap at almost any kernel address and
	  execute a callback function.  register_kprobe() establishes
	  a probepoint and specifies the callback.  Kprobes is useful
	  for kernel debugging, non-intrusive instrumentation and testing.
	  If in doubt, say "N".

config DEBUG_DCFLUSH
	bool "D-cache flush debugging"
	depends on DEBUG_KERNEL

config STACK_DEBUG
	depends on DEBUG_KERNEL
	bool "Stack Overflow Detection Support"

config DEBUG_BOOTMEM
	depends on DEBUG_KERNEL
	bool "Debug BOOTMEM initialization"

config DEBUG_PAGEALLOC
	bool "Page alloc debugging"
	depends on DEBUG_KERNEL && !SOFTWARE_SUSPEND
	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 MCOUNT
	bool
	depends on STACK_DEBUG
	default y

config FRAME_POINTER
	bool
	depends on MCOUNT
	default y
