Subject: [PATCH 10/12] i386: Introduce head32.c
Date: Mon, 30 Apr 2007 10:32:56 -0600 [thread overview]
Message-ID: <m1647d4ybr.fsf_-_@ebiederm.dsl.xmission.com> (raw)
In-Reply-To: <m1abwp4yd9.fsf_-_@ebiederm.dsl.xmission.com> (Eric W. Biederman's message of "Mon, 30 Apr 2007 10:32:02 -0600")
Copy x86_64 and add a head32.c so we can start moving early
architecture initialization out of assembly.
