It's a _second_ kernel running on the system on top of the
original kernel. It's compiled just like any other program; it is loaded
from the command line, initializes itself, and exits.

The original kernel is left just as it is. We take a complete
secnd copy of the kernel sources, apply this patch, and compile that into
the UML executable.
Take a look at some of the UML documentation; it explains this
stuff pretty well.
