RE: Compiling kernel with -g option.

Relocation truncated to fit errors are typically caused by
your executable exceeding 16Mbytes (24 bits) in size (assuming
it isn't caused by missing modules and thus unresolved references).

In this case, however, it was clear that the problem WAS due to
unresolved references -- specifically, the "copy_to_user" refs.
That's always going to happen if you turn off optimization, because
those are inlined functions, and you have to use at least -O1 to
get those to be compiled as inlines (at least with gcc).

I've never seen a 16 MB linux kernel, even with -g turned on; I
guess you might be able to do it if you enabled every driver and
option, but my mid-sized vmlinux, with -g, is 8 MB.
