Subject: [PATCH 4.9 83/83] x86/kbuild: enable modversions for symbols exported from asm
Date: Wed,  4 Jan 2017 21:07:15 +0100	[thread overview]
Message-ID: <20170104200449.888148415@linuxfoundation.org> (raw)
In-Reply-To: <20170104200446.541604386@linuxfoundation.org>

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Adam Borowski <kilobyte@angband.pl>

commit 334bb773876403eae3457d81be0b8ea70f8e4ccc upstream.

Commit 4efca4ed ("kbuild: modversions for EXPORT_SYMBOL() for asm") adds
modversion support for symbols exported from asm files. Architectures
must include C-style declarations for those symbols in asm/asm-prototypes.h
in order for them to be versioned.

Add these declarations for x86, and an architecture-independent file that
can be used for common symbols.

With f27c2f6 reverting 8ab2ae6 ("default exported asm symbols to zero") we
produce a scary warning on x86, this commit fixes that.
