From 2374d0af29c154d6d989987a94278caed8c13be5 Mon Sep 17 00:00:00 2001 From: LEROY Christophe Date: Tue, 20 Jan 2015 10:57:33 +0100 Subject: [PATCH] powerpc/8xx: remove remaining unnecessary code in FixupDAR Since commit 33fb845a6f01 ("powerpc/8xx: Don't use MD_TWC for walk"), MD_EPN and MD_TWC are not writen anymore in FixupDAR so saving r3 has become useless.
