Aneesh Kumar K.V bd5050e38a powerpc/mm/radix: Change pte relax sequence to handle nest MMU hang ... When relaxing access (read -> read_write update), pte needs to be marked invalid to handle a nest MMU bug. We also need to do a tlb flush after the pte is marked invalid before updating the pte with new access bits. We also move tlb flush to platform specific __ptep_set_access_flags. This will help us to gerid of unnecessary tlb flush on BOOK3S 64 later. We don't do that in this patch. This also helps in avoiding multiple tlbies with coprocessor attached.
