+       depends on DEBUG_KERNEL
+       help
+         If you say Y here the kernel will use a 4Kb stacksize for the
+         kernel stack attached to each process/thread. This facilitates
+         running more threads on a system and also reduces the pressure
+         on the VM subsystem for higher order allocations. This option
+         will also use IRQ stacks to compensate for the reduced stackspace.

+config METAG_FUNCTION_TRACE
+       bool "Output Meta real-time trace data for function entry/exit"
+       help
+         If you say Y here the kernel will use the Meta hardware trace
+         unit to output information about function entry and exit that
+         can be used by a debugger for profiling and call-graphs.
+
+config METAG_POISON_CATCH_BUFFERS
+       bool "Poison catch buffer contents on kernel entry"
+       help
+         If you say Y here the kernel will write poison data to the
+         catch buffer registers on kernel entry. This will make any
+         problem with catch buffer handling much more apparent.
