+ * Name: sim_smp_hook
+ *
+ * Description:
+ *   This is a mindless little hook between sim_idle_trampoline() and the
+ *   real IDLE task logic.  This is only needed because we need to access
+ *   elements of the TCB in the simulation domain but sim_idle_trampoline()
+ *   lies in the host domain.
+ *
+ * Input Parameters:
+ *   None
+ *
+ * Returned Value:
+ *   None (should not return)
+ *
