#     arch/powerpc/mm/hugetlb: NestMMU workaround for hugetlb mprotect RW upgrade
#     
#     NestMMU requires us to mark the pte invalid and flush the tlb when we do a
#     RW upgrade of pte. We fixed a variant of this in the fault path in commit
#     Fixes: bd5050e38aec ("powerpc/mm/radix: Change pte relax sequence to handle nest MMU hang")
