Given that the last patch killed the last previously existing
user of on_each_cpu_cond_mask there are now the only users.

 	if (info->freed_tables) {
-		smp_call_function_many(cpumask, flush_tlb_func,
-			       (void *)info, 1);
+		on_each_cpu_cond_mask(NULL, flush_tlb_func, (void *)info, true,
+				      cpumask);

.. 

+		on_each_cpu_cond_mask(NULL, flush_tlb_func, (void *)info, true,
+				      cpumask);

Which means the cond_func is unused, and thus on_each_cpu_cond_mask can
go away entirely in favor of on_each_cpu_cond.
