Chris? Max, I think you are right that in an earlier attempt to support cache aliasing, we tried to allocate pages with the correct 'color', and cached pages locally (if I remember correctly). The approach we use now doesn't require that so the suggested patches are fine. (Note that cache aliasing support hasn't been committed to mainline yet) Thanks, -Chris -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
