Subject: [PATCH] m68k: Add forward declaration for show_registers()

There are several forward declarations for show_registers() in C source
files.  Replace these by a single common forward declaration in
<asm/processor.h>, and include <asm/processor.h> where needed.

Signed-off-by: Geert Uytterhoeven <geert@...ux-m68k.org>

To be queued in the m68k tree for v5.20.
