[SPARC64] mm: Do not flush TLB mm in tlb_finish_mmu()
It isn't needed any longer, as noted by Hugh Dickins. We still need the flush routines, due to the one remaining call site in hugetlb_prefault_arch_hook(). That can be eliminated at some later point, however. Signed-off-by: David S. Miller <davem@davemloft.net>
