[IA64-SGI] fix bte_copy() calling get_nasid() while preemptible
bte_copy() calls calls get_nasid(), which will get flagged if preemption if enabled. raw_smp_processor_id() is used instead. It is OK if we migrate off node. Signed-off-by: Russ Anderson (rja@sgi.com) Signed-off-by: Tony Luck <tony.luck@intel.com>
