+config DEBUG_STACKOVERFLOW
+       bool "Check for stack overflows"

+       help
+         This option will cause messages to be printed if free stack space
+         drops below a certain limit.
+
+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

+       depends on DEBUGGER && (BROKEN || PPC_GEN550 || 4xx)
+       select DEBUG_INFO

+         over the gdb stub.

+config XMON

+         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

+       depends on XMON
+       help
+         xmon is normally disabled unless booted with 'xmon=on'.

+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.
+

+         Unless you are intending to debug the kernel with one of these
+         machines, say N here.
