When building with W=1:
arch/m68k/kernel/signal.c:756:18: warning: no previous prototype for ‘do_sigreturn’ [-Wmissing-prototypes]
756 | asmlinkage void *do_sigreturn(struct pt_regs *regs, struct switch_stack *sw)
| ^~~~~~~~~~~~
arch/m68k/kernel/signal.c:783:18: warning: no previous prototype for ‘do_rt_sigreturn’ [-Wmissing-prototypes]
783 | asmlinkage void *do_rt_sigreturn(struct pt_regs *regs, struct switch_stack *sw)
| ^~~~~~~~~~~~~~~
arch/m68k/kernel/signal.c:1112:17: warning: no previous prototype for ‘do_notify_resume’ [-Wmissing-prototypes]
1112 | asmlinkage void do_notify_resume(struct pt_regs *regs)
| ^~~~~~~~~~~~~~~~
Fix this by introducing a new header file "signal.h" for holding the
prototypes of functions implemented in arch/m68k/kernel/signal.c.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
