+         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.
