See my reply to Wil. The code to allocate gigantic pages from CMA depends on the arch independent definition of gigantic page which is 'order >= MAX_ORDER'. -- Mike Kravetz _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
