[SPARC64] mm: simpler tlb_flush_mmu
Minor simplification to the sparc64 tlb_flush_mmu: tlb_remove_page set need_flush only after handling the tlb_fast_mode case, then tlb_flush_mmu need not consider whether it's tlb_fast_mode. Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: David S. Miller <davem@davemloft.net>
