Right. I don't know why it fails for `phys_to_virt' where `address' is of the `unsigned long' type, but there are other places where the macros themselves are cast to `void *'. We may want to rework that stuff, but not necessarily on this occasion. Use an explicit cast of the macro to `s64' here then, as my other suggestion was. Anything is better than hardcoded magic numbers. Maciej
