I think that's good for normal things, but it's not unreasonable to want to map > 4 GB of memory at once for an Infiniband device. So maybe we would want some heuristics about the size of the mapping being requested or the amount of 32-bit space left to decide whether a mapping should be below 4 GB. - R. - 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/
