powerpc/mm/radix: Add missing tlb flush
This should not have any impact on hash, because hash does tlb invalidate with every pte update and we don't implement flush_tlb_* functions for hash. With radix we should make an explicit call to flush tlb outside pte update. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
