Anyhow, yes thats fine with me. I'll send out a new version here today renamed to CONFIG_SPARSEMEM. This also has a few fixes as a result of futher testing. -mhp seems as good a place as any for the moment. -apw -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
