Message-Id: <47610C0C.76E4.0078.0@novell.com>
Date: Thu, 13 Dec 2007 09:40:12 +0000
From: "Jan Beulich" <jbeulich@...ell.com>

Cc: <linux-kernel@...r.kernel.org>
Subject: [PATCH] x86: make __{save,restore}_processor_state static
.. allowing to remove their declarations from a global include file
(the symbols don't exist for anything but x86).
Likewise for 64-bits' fix_processor_context(), just that that one was
properly declared in an arch-specific header.
