[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(). Signed-off-by: Dimitri Sivanich <sivanich@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
