+          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 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".

+        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.
+
+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 GDB_CONSOLE

+        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.
