  14          If you say Y here you will confirm the start and the end of
  15          decompressing Linux seeing "Uncompressing Linux... " and
  16          "Ok, booting the kernel.\n" on console.

  20        depends on DEBUG_KERNEL
  21        help
  22          Kprobes allows you to trap at almost any kernel address and
  23          execute a callback function.  register_kprobe() establishes
  24          a probepoint and specifies the callback.  Kprobes is useful
  25          for kernel debugging, non-intrusive instrumentation and testing.
  26          If in doubt, say "N".

  33        help
  34          If you say Y here, it will be possible to remotely debug the kernel
  35          using gdb. This enlarges your kernel ELF image disk size by several
  36          megabytes and requires a machine with more than 16 MB, better 32 MB
  37          RAM to avoid excessive linking time. This is only useful for kernel
  38          hackers. If unsure, say N.

  44          If you say Y here, GDB stub will break into the program as soon as
  45          possible, leaving the program counter at the beginning of
  46          start_kernel() in init/main.c.

  52          If you are using GDB for remote debugging over a serial port and
  53          would like kernel messages to be formatted into GDB $O packets so
  54          that GDB prints them as program output, say 'Y'.

  61          during execution of the GDB stub routines. Such messages will be
  62          displayed on ttyS0 if that isn't the GDB stub's port, or ttySM0
