+config DEBUG_STACKOVERFLOW
+        bool "Check for stack overflows"
+        depends on DEBUG_KERNEL && PPC64
+        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 && PPC64
+        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 && PPC64
+        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 KGDB
+        bool "Include kgdb kernel debugger"
+        depends on DEBUGGER && (BROKEN || PPC_GEN550 || 4xx)
+        select DEBUG_INFO
+        help
+          Include in-kernel hooks for kgdb, the Linux kernel source level
+          debugger.  See <http://kgdb.sourceforge.net/> for more information.
+          Unless you are intending to debug the kernel, say N here.

+        depends on KGDB && 8xx || CPM2
+        help
+          If you enable this, all serial console messages will be sent
+          over the gdb stub.
+          If unsure, say N.
+
+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"
+        depends on PPC64
+        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.
+
+config BDI_SWITCH
+        bool "Include BDI-2000 user context switcher"
+        depends on DEBUG_KERNEL && PPC32
+        help
+          Include in-kernel support for the Abatron BDI2000 debugger.
+          Unless you are intending to debug the kernel with one of these
+          machines, say N here.
+
+config BOOTX_TEXT
+        bool "Support for early boot text console (BootX or OpenFirmware only)"
+        depends PPC_OF && !PPC_ISERIES
+        help
+          Say Y here to see progress messages from the boot firmware in text
+          mode. Requires either BootX or Open Firmware.
