ia64: cpumask fix for is_affinity_mask_valid()
Impact: cleanup
The function prototype should use 'struct cpumask *' to declare
cpumask arguments (instead of cpumask_var_t).
Note: arch/ia64/kernel/irq.c still had the following "old cpumask_t" usages:
105: cpumask_t mask = CPU_MASK_NONE;
107: cpu_set(cpu_logical_id(hwid), mask);
110: irq_desc[irq].affinity = mask;
... replaced with a simple "cpumask_of(cpu_logical_id(hwid))".
161: new_cpu = any_online_cpu(cpu_online_map);
194: time_keeper_id = first_cpu(cpu_online_map);
... replaced with cpu_online_mask refs.
