 The linker will only generate function tables, it will not generate code to
 call these functions. If you're using the feature in some other than the
 existing C environments, you have to write code to call all functions in a
-linker generated table yourself. See the <tt>/condes/ and <tt/callirq/ modules
+linker generated table yourself. See the <tt/condes/ and <tt/callirq/ modules
 in the C runtime for an example on how to do this.
