When building with W=1: CC arch/m68k/68000/ints.o arch/m68k/68000/ints.c:77:6: warning: no previous prototype for ‘process_int’ [-Wmissing-prototypes] void process_int(int vec, struct pt_regs *fp) ^~~~~~~~~~~ arch/m68k/68000/ints.c:153:13: warning: no previous prototype for ‘trap_init’ [-Wmissing-prototypes] void __init trap_init(void) ^~~~~~~~~ Include linux/cpu.h to get the prototype for trap_init(). Create a local ints.h for prototype of process_int(). Also mark process_int() as asmlinkage, since it is called from the first level interrupt assembly handler.
