The simple fix still leaves ample room for overflows in calculating start
address and size of a RDB partition, though such overflows should only be 
seen in rather unusual cases. To address these potential overflows, checks
are added in the second patch of this series. Comments by Geert have been   
addressed in full. 

Reviewed-by tags by Geert and Christoph added. Fixes and prerequisites
for stable backport added. 

Cheers,

        Michael
