When building with W=1:
arch/m68k/kernel/ints.c:165:17: warning: no previous prototype for ‘handle_badint’ [-Wmissing-prototypes]
165 | asmlinkage void handle_badint(struct pt_regs *regs)
| ^~~~~~~~~~~~~
Fix this by introducing a new header file "ints.h" for holding the
prototypes of functions implemented in arch/m68k/kernel/ints.c.
