Subject: [PATCH 05/15] x86: use initial_code for i386
Date: Mon, 9 Jun 2008 11:16:48 -0300 [thread overview]
Message-ID: <1213021018-14159-6-git-send-email-gcosta@redhat.com> (raw)
In-Reply-To: <1213021018-14159-5-git-send-email-gcosta@redhat.com>
x86_64 jumps to whatever is written in "initial_code" symbol,
instead of a fixed address. Do it for i386 too. It will allow us
to integrate more of the smp boot code.
