+		Enable support for prioritized interrupts.
+
+		NOTE: The use of interrupt priorities implies that you also have
+		support for nested interrupts.  Most architectures do not support
+		nesting of interupts or, if they do, they only supported nested
+		interrupts with certain configuration options.  So this selection
+		should be used with caution.
