Change that exception and make it a "bool". The "lookup_still_valid" field is used as a "bool". Make it one. Convert vm_fault_hold()'s Boolean variables that are only used internally to "bool". Add a comment describing why the one remaining "boolean_t" was not converted. Merge and sort vm_fault_hold()'s "int" variable definitions. END
