+#define cpu_online_map		(*(cpumask_t *)cpu_online_mask)

This bit seems to be the reason why linux-next isn't building for ia64
(tag next-20081029
and next-20081030). With this error:

>   CC      arch/ia64/kernel/asm-offsets.s

> arch/ia64/include/asm/smp.h:60: error: expected ')' before 'cpu_online_mask'

Fix is trivial ... delete the declaration of cpu_online_map from
arch/ia64/include/asm/smp.h
