+config DEBUG_DECOMPRESS_KERNEL
+	bool "Using serial port during decompressing kernel"
+	depends on DEBUG_KERNEL
+	default n
+	help
+	  If you say Y here you will confirm the start and the end of
+	  decompressing Linux seeing "Uncompressing Linux... " and
+	  "Ok, booting the kernel.\n" on console.
+
+config TEST_MISALIGNMENT_HANDLER
+	bool "Run tests on the misalignment handler"
+	depends on DEBUG_KERNEL
+	default n
+	help
+	  If you say Y here the kernel will execute a list of misaligned memory
+	  accesses to make sure the misalignment handler deals them with
+	  correctly.  If it does not, the kernel will throw a BUG.
+
+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 GDBSTUB
+	bool "Remote GDB kernel debugging"
+	depends on DEBUG_KERNEL && DEPRECATED
+	select DEBUG_INFO
+	select FRAME_POINTER
+	help
+	  If you say Y here, it will be possible to remotely debug the kernel
+	  using gdb. This enlarges your kernel ELF image disk size by several
+	  megabytes and requires a machine with more than 16 MB, better 32 MB
+	  RAM to avoid excessive linking time. This is only useful for kernel
+	  hackers. If unsure, say N.
+
+	  This is deprecated in favour of KGDB and will be removed in a later
+	  version.
+
+config GDBSTUB_IMMEDIATE
+	bool "Break into GDB stub immediately"
+	depends on GDBSTUB
+	help
+	  If you say Y here, GDB stub will break into the program as soon as
+	  possible, leaving the program counter at the beginning of
+	  start_kernel() in init/main.c.
+
+config GDBSTUB_ALLOW_SINGLE_STEP
+	bool "Allow software single-stepping in GDB stub"
+	depends on GDBSTUB && !SMP && !PREEMPT
+	help
+	  Allow GDB stub to perform software single-stepping through the
+	  kernel.  This doesn't work very well on SMP or preemptible kernels as
+	  it uses temporary breakpoints to emulate single-stepping.
+
+config GDB_CONSOLE
+	bool "Console output to GDB"
+	depends on GDBSTUB
+	help
+	  If you are using GDB for remote debugging over a serial port and
+	  would like kernel messages to be formatted into GDB $O packets so
+	  that GDB prints them as program output, say 'Y'.
+
+config GDBSTUB_DEBUGGING
+	bool "Debug GDB stub by messages to serial port"
+	depends on GDBSTUB
+	help
+	  This causes debugging messages to be displayed at various points
+	  during execution of the GDB stub routines. Such messages will be
+	  displayed on ttyS0 if that isn't the GDB stub's port, or ttySM0
+	  otherwise.
+
+config GDBSTUB_DEBUG_ENTRY
+	bool "Debug GDB stub entry"
+	depends on GDBSTUB_DEBUGGING
+	help
+	  This option causes information to be displayed about entry to or exit
+	  from the main GDB stub routine.
+
+config GDBSTUB_DEBUG_PROTOCOL
+	bool "Debug GDB stub protocol"
+	depends on GDBSTUB_DEBUGGING
+	help
+	  This option causes information to be displayed about the GDB remote
+	  protocol messages generated exchanged with GDB.
+
+config GDBSTUB_DEBUG_IO
+	bool "Debug GDB stub I/O"
+	depends on GDBSTUB_DEBUGGING
+	help
+	  This option causes information to be displayed about GDB stub's
+	  low-level I/O.
+
+config GDBSTUB_DEBUG_BREAKPOINT
+	bool "Debug GDB stub breakpoint management"
+	depends on GDBSTUB_DEBUGGING
+	help
+	  This option causes information to be displayed about GDB stub's
+	  breakpoint management.
