类型参数名称
boolon
160  raw_spin_lock_irqsave( & cmci_discover_lock protects against parallel discovery attempts* which could race against each other., flags)
161  owned等于this_cpu_ptr(CMCI can be delivered to multiple cpus that share a machine check bank* so we need to designate a single cpu to process errors logged in each bank* in the interrupt handler (otherwise we would have many races and potential)
163  rdmsrl(MSR_IA32_MCx_CTL2(bank), val)
165  如果on则val或等于CTL2 register defines
167  否则val与等于CTL2 register defines 的反
