[IA64] Fix another IA64 preemption problem
There's another problem shown up by Ingo's recent patch to make smp_processor_id() complain if it's called with preemption enabled. local_finish_flush_tlb_mm() calls activate_context() in a situation where it could be rescheduled to another processor. This patch disables preemption around the call. Signed-off-by: Peter Chubb <peterc@gelato.unsw.edu.au> Signed-off-by: Tony Luck <tony.luck@intel.com>
