Page migration is a little iffier, but that can be turned off. Embedded platforms with multiple memories (and a different cost per memory) are quite common, and they're getting large enough to offset the overhead of a pgdat + bootmem map. We have them on nommu also, but that's not been hacked up generically yet. - 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/
