In the commit method of the login module, a privileged code clears up the current subject and replaces the principals, and the public and private credentials.
在登录模块的commit方法中，可以使用特权代码清除当前主题并替换相应的主体、公开的和私有的凭据。
Kernel space is flagged in the page tables as exclusive to privileged code (ring 2 or lower), hence a page fault is triggered if user-mode programs try to touch it.
系统内核所使用的内存空间通过特权码（privileged code，2级或者更低）来标记，以防止用户模式的程序访问到内核空间而发生页面错误。
As expected, the program has received a SIGILL (signal number 4) with an si code of 5, which is set when a privileged opcode is executed by a user-space program.
正如我们期望的一样，这个程序会接收到一个SIGILL(信号编号为4)信号，其si代码为5，这是在用户空间的程序执行特权操作时产生的。
Some kernel code is needed to use the SPUs from a Linux application, since the controlling registers are only accessible from the PPE in privileged mode.
在Linux程序中使用SPU需要使用一部分内核代码，因为控制寄存器只能从PPE中使用特权模式进行访问。
A similar example is runtime code scanning used by full virtualization solutions to find and redirect privileged instructions (to work around issues in certain processor instruction sets).
类似的一个例子是完全虚拟化解决方案通过运行时代码扫描来查找和重定向特权指令(用来解决特定处理器指令集的一些问题)。
Recall that kernel mode represents the privileged mode for code execution, while user mode represents the non-privileged mode (for programs running outside the kernel).
回想一下内核模式表示代码执行的特权模式，而用户模式则表示非特权模式（用于那些运行在内核之外的程序）。
