The patch titled
Subject: arch/ia64: remove references to cpu_*_map
has been removed from the -mm tree. Its filename was
arch-ia64-remove-references-to-cpu__map.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: arch/ia64: remove references to cpu_*_map
This was marked as obsolete for quite a while now.. Now it is time to
remove it altogether. And while doing this, get rid of first_cpu() as
well. Also, remove the redundant setting of cpu_online_mask in
smp_prepare_cpus() because the generic code would have already set cpu 0
in cpu_online_mask.
