Subject: [PATCH] [4/20] x86: Move nop declarations into separate include file
Date: Thu, 3 Jan 2008 01:49:59 +0100 (CET) [thread overview]
Message-ID: <20080103004959.54D6314D40@wotan.suse.de> (raw)
In-Reply-To: <20080103149.088038000@suse.de>
Moving things out of processor.h is always a good thing.
Also needed to avoid include loop in later patch.
