I did this long time ago (on a 2.4 kernel), trying to avoid a hardware problem. I re-ordered the zones so that ZONE_DMA came after ZONE_NORMAL. Since the DMA memory was quite small (less than 1MB), I also put a "break" before "case ZONE_DMA" in the build_zonelists_node() functions to avoid the allocation fallback. -- Catalin - 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/
