But the ELF image must be laid out with certain expectations regarding the maximum support page size. Otherwise, something (kernel or dynamic linker) needs to perform copies or upgrade conflicting permissions within one page to a superset of all permissions. I don't think we have code for that today, and we wouldn't necessarily want to implement that, I think. Thanks, Florian
