Andrew, I'd rather the ELF_ET_DYN_BASE changes not be in -mm yet. I think it's the wrong approach. Patch 1 (comment update) is fine. Patches 3 and 4 need some (minor?) adjustments, but the ELF_DYN_BASE patches need much more thought, IMO (I've sent a separate email about those.) And please add me to explicit the Cc list for this series. -Kees -- Kees Cook Pixel Security
