ia64 doesn't seem to care ... I changed the one use of .text.head
to be just .text.  There are a couple of new "section mismatches"
(start_ap -> start_secondary and start_ap -> start_kernel), but
it still boots.

The start_ap code is still needed for hotplug cpu on ia64. So .text.init
won't work for me.
