类型参数名称
const struct cpumask *cpumask
intvector
291  mask等于cpumask_bits - get the bits in a cpumask*@maskp: the struct cpumask ** You should only assume nr_cpu_ids bits of this mask are valid. This is* a macro so it's const-correct.(cpumask)[0]
294  如果非mask则返回
297  local_irq_save(flags)
298  WARN_ON(mask & ~cpumask_bits - get the bits in a cpumask*@maskp: the struct cpumask ** You should only assume nr_cpu_ids bits of this mask are valid. This is* a macro so it's const-correct.(cpu_online_mask)[0])
299  This is used to send an IPI with no shorthand notation (the destination is* specified in bits 56 to 63 of the ICR).
300  local_irq_restore(flags)
