While GENMASK may do the job, the code is already quite obscure, so I'm going to stick with the minimal delta to get this right, namely - align_mask = 0xffffffffffffffffl >> (64 - align_order); + align_mask = ~0ul >> (BITS_PER_LONG - align_order); --Sowmini -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
