This is enabled only with radix translation and 1G hugepage size. This will be used with devdax device memory with a namespace alignment of 1G. Anon transparent hugepage is not supported even though we do have helpers checking pud_trans_huge(). We should never find that return true. The only expected pte bit combination is _PAGE_PTE | _PAGE_DEVMAP. Some of the helpers are never expected to get called on hash translation and hence is marked to call BUG() in such a case.
