OK, thanks.

For me, it is not a real world issue, the user should not let it happen.
It is only about building test (COMPILE_TEST).

And for me, the root cause is:

- init section is the last section which can be dropped easily.

- but init section includes l1 section (which may also include sched
section).

- l1 section has fixed address. If the kernel is too big, l1 section
will be overwrite, so ld report "reloc overflow".

Welcome any other ideas, discussions or completions.


Thanks.
