cpuhp_issue_call

函数名称：Call the startup/teardown function for a step either on the AP or* on the current CPU.

函数原型：static int cpuhp_issue_call(int cpu, enum cpuhp_state state, bool bringup, struct hlist_node *node)

返回类型：int

参数：

类型	参数	名称
int	cpu
enum cpuhp_state	state
bool	bringup
struct hlist_node *	node
