kernel: mips_disable_fpu: initialize fault_addr in fpu_emulator_cop1Handler
Code calling fpu_emulator_cop1Handler will pass on fault_addr, making gcc complain about it not being initialized when the FPU emulator is disabled. Fixes: arch/mips/kernel/traps.c: In function 'do_fpe': arch/mips/kernel/traps.c:864:22: error: 'fault_addr' may be used uninitialized in this function [-Werror=maybe-uninitialized] process_fpemu_return(sig, fault_addr, fcr31); ^ arch/mips/kernel/traps.c: In function 'do_ri': arch/mips/kernel/traps.c:806:22: error: 'fault_addr' may be used uninitialized in this function [-Werror=maybe-uninitialized] process_fpemu_return(sig, fault_addr, fcr31); ^ arch/mips/kernel/traps.c:763:15: note: 'fault_addr' was declared here void __user *fault_addr; ^ arch/mips/kernel/traps.c: In function 'do_cpu': arch/mips/kernel/traps.c:1421:28: error: 'fault_addr' may be used uninitialized in this function [-Werror=maybe-uninitialized] if (!process_fpemu_return(sig, fault_addr, fcr31) && !err) ^ cc1: all warnings being treated as errors make[7]: *** [arch/mips/kernel/traps.o] Error 1 Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 46184
