[PATCH] ia64: export cpu_core_map

[Ben Hutchings <bhutchings@solarflare.com>]

cpu_core_map is referenced by the topology_core_siblings() macro, which is
now used by the sfc driver.  Matthew Wilcox reported that the driver failed
to link because that symbol is not exported.

I have not yet tested this as we have limited ia64 kit here.  Matthew,
please could you check that this builds at least?

Ben.
