-
-	  This option will slow down process creation somewhat.
-
-config DEBUGGER

-	  intending to debug the kernel, say N here.

-	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.

-	  If you say Y here the kernel will use separate kernel stacks
-	  for handling hard and soft interrupts.  This can help avoid
