The practice shows both might be resolved in generic kernels. If you
want save 4k and drop other-platform-specific parts at run-time, put
platform specific parts in their own sections (like initfunc/initdata).
Also, Ralf showed it's possible to fix the code at run-time to have fast
kernels. I agree the sources become much uglier but it works.
