That is how Linus wanted hugepages to be done initially. Otherwise
we would have never gotten the separate hugetlbfs.
If you want a complete second VM that does everything in variable page
sizes then please redesign the original VM instead instead of recreating
all its code in mm/hugetlb.c. Thank you.
