Subject: [Qemu-devel] [PATCH 2/4] target-i386: Introduce x86_cpuid_version_set_model()
Date: Fri, 17 Feb 2012 17:46:02 +0100 [thread overview]
Message-ID: <1329497164-20086-3-git-send-email-afaerber@suse.de> (raw)
In-Reply-To: <1329497164-20086-1-git-send-email-afaerber@suse.de>
Move the logic for setting the model and extended model fields
into a helper function.
To make the function self-contained and to prepare for future
unordered/multiple uses, mask out any previous model values first.
