prefer_mwait_c1_over

函数名称：Intel Core2 and older machines prefer MWAIT over HALT for C1.* We can't rely on cpuidle installing MWAIT, because it will not load* on systems that support only C1 -- so the boot default must be MWAIT.

函数原型：static int prefer_mwait_c1_over_halt(const struct cpuinfo_x86 *c)

返回类型：int

参数：
