From 0157141ae29d7a0998b9f040e577895980430d89 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Tue, 6 Jan 2009 12:52:41 -0800 Subject: [PATCH] sparc: refactor code in fault_32.c The sparc allmodconfig build broke due to enabling of the branch_tracer that does some very clever things with all if conditions. This caused my gcc 3.4.5 to be so confused that it emitted a warning: arch/sparc/mm/fault_32.c: In function `do_sparc_fault': arch/sparc/mm/fault_32.c:176: warning: 'fixup' might be used uninitialized in this function And with -Werror this broke the build. Refactor code so it: 1) becomes more readable 2) no longer emit a warning with the branch_tracer enabled Signed-off-by: Sam Ravnborg Signed-off-by: David S.
