[IA64] Avoid overflowing ia64_cpu_to_sapicid in acpi_map_lsapic()
acpi_map_lsapic tries to stuff a long into ia64_cpu_to_sapicid[], which can only hold ints, so let's fix that. We need to update the signature of acpi_map_cpu2node() too. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
