I look at this from the perspective of how much return do we get on investing effort into making it possible for every platform to be built as part of consolidated zImage. I don't expect distros (the main users of a single zImage IMHO) to spend many cycles on older platforms and those of us who still have some of them sitting around to use are generally developers who are going to be doing a lot of builds anyways... ~Deepak -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
