From: Paolo 'Blaisorblade' Giarrusso <blaisorblade_spam@yahoo.it>
UML has his own initcall mechanism to handle his special userspace
initialization (they are called in different moments, so they are indeed
It must also duplicate some definition for the benefit of userspace code - but
those definition weren't in sync with the main code. Also, the UML own macros
missed __attribute_used__. Both problems are fixed by this patch.
