I think it should in general work for the kernel too, since as far as
I can tell, it fundamentally fixes the issue that linker scripts will
set symbol addresses to possibly alias other symbols.
So from a compiler standpoint, I think our "begin/end" linker script
symbols can be seen as interposing a larger array and give bounds for
it. No>
