>From Dan Williams:
Here is another occasion where we want special-case hugetlbfs enabling
to also apply to device-dax. I started to wonder what other hstate
conversions we might do beyond ->split() and ->pagesize(), but this
appears to be the last of the usages of hstate_vma() in
generic/non-hugetlbfs specific code paths.

I fixed up the powerpc build issue that Michal reported by restoring the
original location of the function and making the symbol weak.

      mm, hugetlbfs: introduce ->pagesize() to vm_operations_struct
      device-dax: implement ->pagesize() for smaps to report MMUPageSize
