函数名称：probe_xeon_phi_r3mwait

函数原型：static void probe_xeon_phi_r3mwait(struct cpuinfo_x86 *c)

返回类型：void

参数：

类型参数名称
struct cpuinfo_x86 *c
110  如果CPU family 不等于6则返回
113  当:x86_model恒等于Knights Landing
114  当:x86_model恒等于Knights Mill
115  退出
116  默认
117  返回
120  如果ring3mwait_disabled则返回
123  set_cpu_cap(c, Ring 3 MONITOR/MWAIT instructions )
124  this_cpu_or(msr_misc_features_shadow, 1UL << MSR_MISC_FEATURES_ENABLES_RING3MWAIT_BIT)
127  如果c恒等于common cpu data for all cpus 则HWCAP2 supplies mask with kernel enabled CPU features, so that* the application can discover that it can safely use them.* The bits are defined in uapi/asm/hwcap2.h.或等于MONITOR/MWAIT enabled in Ring 3
