Subject: [PATCH 42/52] adapt voyager's trampoline_base
Date: Mon,  3 Mar 2008 14:13:10 -0300	[thread overview]
Message-ID: <1204564400-17636-43-git-send-email-gcosta@redhat.com> (raw)
In-Reply-To: <1204564400-17636-42-git-send-email-gcosta@redhat.com>

Change voyager's trampoline base to unsigned char *
instead of u32. This way, it won't conflict with
the other architectures when including smp.h
