参数：

类型参数名称
struct tsc_adjust *cur
s64bootval

boolbootcpu
99  如果bootcpu且bootval不等于0则
100  如果此条件成立可能性大(为编译器优化)(!tsc_async_resets)则
101  打印警告信息(FW_BUG* Add this to a message where you are sure the firmware is buggy or behaves* really stupid or out of spec"TSC ADJUST: CPU%u: %lld force to 0\n", cpu, bootval)
103  wrmsrl(MSR_IA32_TSC_ADJUST, 0)
104  bootval等于0
105  否则
106  打印信息("TSC ADJUST: CPU%u: %lld NOT forced to 0\n", cpu, bootval)
110  adjusted等于bootval
