The per-entry could result in a much smaller range, there's no point in flushing tlbs for unpopulated pages. Anyway, I don't think even think we'd need to change the API for that, you could track the entire range through tlb_start_vma() if you wanted (although nobody does that IIRC). -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
