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.
