参数：

类型参数名称
unsigned inttype
struct pt_regs *regs
127  desc等于nmi_to_desc(type)
129  handled等于0
131  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
143  delta等于Do not use outside of architecture code which knows its limitations.* sched_clock() has no promise of monotonicity or bounded drift between* CPUs, use (which you should not) requires disabling IRQs.* Please use one of the three interfaces below.
144  thishandled等于handler(type, regs)
145  handled加等于thishandled
146  delta等于Do not use outside of architecture code which knows its limitations.* sched_clock() has no promise of monotonicity or bounded drift between* CPUs, use (which you should not) requires disabling IRQs.* Please use one of the three interfaces below.减delta
147  trace_nmi_handler(handler, (int)delta, thishandled)
149  nmi_check_duration(a, delta)
152  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
