在系统中真正被所有进程都使用的内核通信方式是系统调用，例如当进程请求内核服务
时，就使用的是系统调用。一般情况下，进程是不能够存取系统内核的，它不能存取内核使
用的内存段，也不能调用内核函数，CPU 的硬件结构保证了这一点，只有系统调用是一个例
外。-In the system, the real core of communication are all processes using a system call, such as when a process requests kernel services, we are using a system call. Under normal circumstances, the process is not able to access the system kernel, it can not access the memory segment used by the kernel, we can not call the kernel function, the hardware structure of the CPU ensures that only the system call is an exception.
