Ok but what happens if s.o. configures its system with HUGE PAGE support? https://wiki.debian.org/Hugepages

The user-visible page size is 4K, 16K or 64K (according to https://wiki.debian.org/ArchitectureSpecificsMemo, which has similar information for a lot of different architectures). I think we're talking about generating an object file here, which might be used on a different system, so we have to assume the largest size.
