From 0bb0a1149e6fb6d8cfdcbcb2dc54d9a7b37db718 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Tue, 15 May 2018 06:50:47 -0700 Subject: [PATCH] signal/mips: Report FPE_FLTUNK for undiagnosed floating point exceptions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Most mips builds fail with arch/mips/kernel/traps.c: In function ‘force_fcr31_sig’: arch/mips/kernel/traps.c:732:2: error: ‘si_code’ may be used uninitialized in this function Fix the problem by initializing si_code with FPE_FLTUNK (undiagnosed floating point exception).
