Subject: [PATCH v2] m68k: Restore symbol versions for symbols exported from assembly
Date: Tue, 25 Jul 2017 09:09:35 +0200 [thread overview]
Message-ID: <1500966575-4136-1-git-send-email-geert@linux-m68k.org> (raw)
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"

[geert: Add warning messages, match actual prototypes]
Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

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.
