Did you try building without CONFIG_HUGETLB_PAGE defined?  I'm guessing

Yes I did for multiple platforms (s390, arm64, ia64, x86, powerpc etc).

that you need a stub for is_hugepage_only_range().  Or, perhaps add this
to asm-generic/hugetlb.h?

There is already a stub (include/linux/hugetlb.h) when !CONFIG_HUGETLB_PAGE.

Thanks!  I missed that stub in the existing code.  I like the removal of
redundant code.
