+
+Yes, I do. The MIT-licensed patch is posted below. After I finish here, I will 
+also post this material on the VBox forum.
+
+The API changes are as follows:
+
+1. The for_ifa() and endfor_ifa() macros are removed. They are so simple that it 
+is better to turn then into in-line code.
+
+2. Routine smp_call_function() is changed from type int to void.
