-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 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_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 DEBUGGER
-	bool "Enable debugger hooks"
-	depends on DEBUG_KERNEL
-	help
-	  Include in-kernel hooks for kernel debuggers. Unless you are
-	  intending to debug the kernel, say N here.
-
-config XMON
-	bool "Include xmon kernel debugger"
-	depends on DEBUGGER && !PPC_ISERIES
-	help
-	  Include in-kernel hooks for the xmon kernel monitor/debugger.
-	  Unless you are intending to debug the kernel, say N here.
-	  Make sure to enable also CONFIG_BOOTX_TEXT on Macs. Otherwise
-	  nothing will appear on the screen (xmon writes directly to the
-	  framebuffer memory).
-	  The cmdline option 'xmon' or 'xmon=early' will drop into xmon very
-	  early during boot. 'xmon=on' will just enable the xmon debugger hooks.
-	  'xmon=off' will disable the debugger hooks if CONFIG_XMON_DEFAULT is set.
-
-config XMON_DEFAULT
-	bool "Enable xmon by default"
-	depends on XMON
-	help
-	  xmon is normally disabled unless booted with 'xmon=on'.
-	  Use 'xmon=off' to disable xmon init during runtime.
-
-config IRQSTACKS
-	bool "Use separate kernel stacks when processing interrupts"
-	help
-	  If you say Y here the kernel will use separate kernel stacks
-	  for handling hard and soft interrupts.  This can help avoid
-	  overflowing the process kernel stacks.
