+#### The loader needs to have some way to know the kernel's entry
+#### point, that is, the address to which it should jump to start the
+#### kernel.  We handle this by writing the linker script kernel.lds.S
+#### so that this module appears at the very beginning of the kernel
+#### image, and then using that as the entry point.
