Aneesh Kumar K.V 5b323367ef arch/powerpc/mm: Nest MMU workaround for 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 bd5050e38a ("powerpc/mm/radix: Change pte relax sequence to handle nest MMU hang"). Do the same for mprotect upgrades. Hugetlb is handled in the next patch.
