[IA64] SMP systems may not have SRAT, still need to mark node0 online.
This only causes a problem in the -mm tree now, but Zou Nan hai and
Shaohua Li sent me this fix so that SMP systems compiled with the
generic kernel (which turns on NUMA and CPUSETS in -mm) won't hit
a BUG_ON in kernel/cpuset.c guarantee_online_mems() which is called
from acpi_early_init()
