Yes.

And before, the actual warnings depended a lot on the kernel
configuration, so making the build break was less of an option.
If Sam's improved section mismatch detection turns out to work fine, we
can fix the issues and start to enable breaking of the build in case of
warnings.

BTW, on m68k I get ca. 160 of them. Most seem to originate in
drivers/isdn/. Doesn't look unsurmountable compared to the number of
other compile warnings fixed during the last few years ;-)
