Gerald Schaefer 1a6baaa0db s390/hugetlb: switch to generic version of follow_huge_pud() 
When pud-sized hugepages were introduced for s390, the generic version of
follow_huge_pud() was using pte_page() instead of pud_page().  This would
be wrong for s390, see also commit 9753412701 ("mm/hugetlb: use
pmd_page() in follow_huge_pmd()").  Therefore, and probably because not
all archs were supporting pud_page() at that time, a private version of
follow_huge_pud() was added for s390, correctly using pud_page().

Since commit 3a194f3f8a ("mm/hugetlb: make pud_huge() and
follow_huge_pud() aware of non-present pud entry"), the generic version of
follow_huge_pud() is now also using pud_page(), and in general behaves
similar to follow_huge_pmd().

Therefore we can now switch to the generic version and get rid of the
s390-specific follow_huge_pud().
