When building with W=1:
arch/m68k/mm/fault.c:22:5: warning: no previous prototype for ‘send_fault_sig’ [-Wmissing-prototypes]
22 | int send_fault_sig(struct pt_regs *regs)
| ^~~~~~~~~~~~~~
arch/m68k/mm/fault.c:68:5: warning: no previous prototype for ‘do_page_fault’ [-Wmissing-prototypes]
68 | int do_page_fault(struct pt_regs *regs, unsigned long address,
| ^~~~~~~~~~~~~
Fix this by introducing a new header file "fault.h" for holding the
prototypes of functions implemented in arch/m68k/mm/fault.c.
