arch/s390: teach arch_get_unmapped_area{_topdown} to handle hugetlb mappings

Browse source

We want to stop special casing hugetlb mappings and make them go through
generic channels, so teach arch_get_unmapped_area{_topdown} to handle
those.

s390 specific hugetlb function does not set info.align_offset, so do the
same here for compatibility.
