From 59871bcd1197014aacdf8e398c407cab70ab74e7 Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Mon, 7 Nov 2005 14:12:08 -0800 Subject: [PATCH] [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.
