参数：

类型参数名称
const struct cpumask *cpumask
intvector
70  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]
71  cpu等于当前cpu ID()
73  如果cpu小于BITS_PER_LONG则__clear_bit - Clears a bit in memory*@nr: the bit to clear*@addr: the address to start counting from* Unlike clear_bit(), this function is non-atomic. If it is called on the same* region of memory concurrently, the effect may be that only one operation
