我们一定听说过有关Linux向新体系架构的移植的新闻，这是因为它做了很多工作来在新体系架构上启动内核（更不要说编译器工具链和其他东西了）。
We hear about ports of Linux to new architectures because it takes some work to bring up a kernel (not to mention the compiler toolchain, and everything else) on a new architecture.

为了在两种截然不同的环境下工作，它们把Forth分别移植到两 种系统上，这样一来就会相对容易些，因为Forth只有一小段内核是属于机器专有的(34:53)。
To work in this hostile environment, they ported Forth to both systems, which was relatively easy because only a very small core of Forth is machine specific (34:53).
如果Linux内核的可移植性和效率还不够好，Linux还提供了其他一些特性，它们无法划分到上面的分类中。
If the portability and efficiency of the Linux kernel weren't enough, it provides some other features that could not be classified in the previous decomposition.

Kernel extensions are not very easy to write and may not be easily portable across various architectures where Linux is supported.
因为很难碰到一个很好的例子，它需要很多没有明显的错误、做作或低级之处的可移植性代码，只有这样才能很好地应用于非内核开发。
Because it's hard to come up with an example of code that requires much porting that isn't either obviously bad, contrived, or too low-level to apply well to non-kernel development.
GPFS可移植层(PL)是一组二进制文件，需要从源代码开始进行本地编译，以便匹配作为GPFS集群一部分的计算机上的Linux内核和配置。
