node_to_cpumask x86_64 broken

[YhLu]

I add some printk in k8_bus.c

node id = 0, node_to_cpumask = f
i= 0 ldtbus = 0
i= 1 ldtbus = 40100
i= 2 ldtbus = 0
node id = 1, node_to_cpumask = 0
i= 0 ldtbus = 0
i= 1 ldtbus = 0
i= 2 ldtbus = 70500
node id = 2, node_to_cpumask = 0
i= 0 ldtbus = 0
i= 1 ldtbus = 0
i= 2 ldtbus = 0
node id = 3, node_to_cpumask = 0
i= 0 ldtbus = 0
i= 1 ldtbus = 0
i= 2 ldtbus = 0
k8-bus.c: bus 5 has empty cpu mask
k8-bus.c: bus 6 has empty cpu mask
k8-bus.c: bus 7 has empty cpu mask

it seems node_to_cpu_mask broken.

I'm using 2.6.11-RC4.
