signal/mips: Report FPE_FLTUNK for undiagnosed floating point exceptions
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). Fixes: f43a54a0d916 ("signal/mips: Use force_sig_fault where appropriate") Cc: linux-mips@linux-mips.org Cc: Eric W.
