Aneesh Kumar K.V 023bdd0023 mm/hugetlb: add prot_modify_start/commit sequence for hugetlb update 
Architectures like ppc64 require to do a conditional tlb flush based on
the old and new value of pte.  Follow the regular pte change protection
sequence for hugetlb too.  This allows the architectures to override the
update sequence.
