If we had linker support for this, however, we might end up
with a patchable kernel. To do this we'd have to store all
needed information in some kernel data section.

While this might increase the size of the kernel by a factor
2, it might be worth it for high-availability sites to compile
their kernel with CONFIG_LIVE_UPDATE...
