Since\nthe cpu_mask parameter passed to irq_set_affinity_hit() has\nonly temporary storage (it's on the stack memory), later\naccesses to it are illegal. Thus reads from the corresponding\nprocfs affinity_hint file can result in paging request oops.\n\nThe issue is fixed by the get_cpu_mask() helper, which provides\na permanent storage for the cpumask_t parameter."
