unmapped memory

基本解释

Dynamic stack growth is the only situation in which access to an unmapped memory region, shown in white above, might be valid.
动态栈增长是唯一的情况中，接触到一个映射的内存区域，在白色上面所示，可能是有效的。
Past that is unmapped memory -- memory for which no corresponding physical location has been assigned either in RAM or on disk.
该地址之后是未被映射的内存 —— 用于在 RAM 或者硬盘中没有分配相应物理位置的内存。

The processor also supports the memory translation process by tapping into the hypervisor (host kernel) when an unmapped memory location is accessed.
处理器也可以通过在访问未经映射的内存位置时使用系统管理程序（主机内核）来支持内存转换进程。
