Heh. So looking at that patch, I can't but help to react that this: #define IOMMU_ERROR_CODE (~(unsigned long) 0) is still pretty ridiculous. Maybe just (-1ul), or for those people who don't understand C unsigned long arithmetic and think that a negative unsigned long looks odd, (~0ul)? Not that this *matters*, but it's a bit odd to have to cast constants to perfectly regular C types.
