函数名称：__rdmsr() and __wrmsr() are the two primitives which are the bare minimum MSR* accessors and should not have any tracing or other functionality piggybacking* on them - those are *purely* for accessing MSRs and nothing more

函数原型：static inline unsigned long long notrace __rdmsr(unsigned int msr)

返回类型：unsigned long long

参数：
