An easy first step would be to move the m68knommu stuff that are implemented differently over as _nommu files, similar to how the _32/_64 renames happened, and then set about converging the two little by little. This is what I've been doing with sh64->sh integration for example, despite fundamental differences like having a totally different register layout and instruction set. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
