This commit:
commit 3e9704739daf46a8ba6593d749c67b5f7cd633d2 Author: Glauber Costa <gcosta@redhat.com> Date: Wed May 28 13:01:54 2008 -0300
x86: boot secondary cpus through initial_code
removed the use of initialize_secondary. However, it didn't update voyager, so the secondary cpus no longer boot. Fix this by adding the initial_code switch to voyager as well.
