[PATCH] x86_64: fix the BP node_to_cpumask

Fix the BP node_to_cpumask.  2.6.14-rc* broke the boot cpu bit as the
cpu_to_node(0) is now not setup early enough for numa_init_array.
cpu_to_node[] is setup much later at srat_detect_node on acpi srat based
em64t machines.  This seems like a problem on amd machines too, Tested on
em64t though.  /sys/devices/system/node/node0/cpumap shows up sanely after
this patch.
