If a fault on hugetlb ever got as far as do_no_page() on ia32, the
kernel would oops on the bogus struct page it gets out of the bogus
pte. I believe the way faults are handled in out-of-tree patches if by
calling hugetlb-specific fault handling stacks instead of
handle_mm_fault() if hugetlb vmas are found by arch code.
