I hope someday s390 will start to include asm-generic/hugetlb.h like all the rest archs, because that's really from the gut feeling of how it should happen.. or the dir should be renamed to asm-generic-without-s390/. :( An expected fix patch attached (to be squashed into patch "mm: Introduce PTE_MARKER swap entry").
