From c816be7b5f24585baa9eba1f2413935f771d6ad6 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 9 Mar 2011 13:00:47 -0800 Subject: [PATCH] sparc32: Fix might-be-used-uninitialized warning in do_sparc_fault(). When we try to handle vmalloc faults, we can take a code path which uses "code" before we actually set it. Amusingly gcc-3.3 notices this yet gcc-4.x does not.
