[IA64] eliminate race condition in smp_flush_tlb_mm
A race condition exists within smp_call_function_many() when called from
smp_flush_tlb_mm(). On rare occasions the cpu_vm_mask can be cleared
while smp_call_function_many is executing, occasionally resulting in a
hung process.
Make a copy of the mask prior to calling smp_call_function_many().
