Add the function prototype of show_stack() in <asm/processor.h> header file so that it is visible before its definition in traps.c.
Although show_stack() is referenced only in traps.c, it is declared with external linkage because, during development, it is often called also by other files for debugging purposes. Declaring it static would increase development effort.
