On powerpc 8xx huge_ptep_get() will need to know whether the given
ptep is a PTE entry or a PMD entry. This cannot be known with the
PMD entry itself because there is no easy way to know it from the
content of the entry.
So huge_ptep_get() will need to know either the size of the page
or get the pmd.
In order to be consistent with huge_ptep_get_and_clear(), give
mm and address to huge_ptep_get().

v2: Add missing changes in arch implementations
v3: Fixed a comment in ARM and missing changes in S390
v4: Fix missing or bad changes in mm/hugetlb.c and rebased on v6.10-rc1
