[PATCH 2/12] UML - non-void functions should return something

[PATCH 2/12] UML - non-void functions should return something

[Jeff Dike]

There are a few functions which are declared to return something,
but don't.  These are actually infinite loops which are forced to be
declared as non-void.  This makes them all return 0.
