#1695826 — [PATCH v2] m68k: Restore symbol versions for symbols exported from assembly

From: Ben Hutchings <ben@decadent.org.uk>

WARNING: EXPORT symbol "__divsi3" [vmlinux] version generation failed, symbol will not be versioned.
WARNING: EXPORT symbol "__umodsi3" [vmlinux] version generation failed, symbol will not be versioned.
WARNING: EXPORT symbol "__mulsi3" [vmlinux] version generation failed, symbol will not be versioned.
WARNING: EXPORT symbol "__modsi3" [vmlinux] version generation failed, symbol will not be versioned.
WARNING: EXPORT symbol "__udivsi3" [vmlinux] version generation failed, symbol will not be versioned.

Add <asm/asm-prototypes.h> so that genksyms knows the types of these
symbols and can generate CRCs for them.

Fixes: d13ffb563044 ("m68k: move exports to definitions"

Based on gccint.info

Several prototypes in the kernel disagree w.r.t. signedness of the
second parameter, and use e.g.

    signed int __divsi3(signed int, unsigned int);

v2:
  - Add warning messages, match actual prototypes.
