When building one ARM configuration, I'm getting this very very useful
error message:
LD .tmp_vmlinux1
`.devexit.text' referenced in section `.data' of drivers/built-in.o: defined in discarded section `.devexit.text' of drivers/built-in.o
`.devexit.text' referenced in section `.data' of drivers/built-in.o: defined in discarded section `.devexit.text' of drivers/built-in.o
make[1]: *** [.tmp_vmlinux1] Error 1
Wow. How much more useful information can it give me? Anyway, let's
try and work out what's going on.
$ arm-linux-objdump --section=.data -r ../build/ixp4xx/drivers/built-in.o |grep '\.devexit\.text'
00002d10 R_ARM_ABS32 .devexit.text
00003038 R_ARM_ABS32 .devexit.text
Okay, now we know where in the .data section these references are. Let's
try to find what's responsible.
$ arm-linux-nm -n ../build/ixp4xx/drivers/built-in.o | grep ' d '|less
00002c8c d driver
00002cfc d driver
00002d6c d hpt37x_timings
...
00003014 d xfer_speeds
00003024 d driver
00003094 d pdc_quirk_drives
How. Very. Informative. They're both in a structure called 'driver'.
$ grep 'struct.* driver *=' drivers -r | wc -l
62
Yes. Well, 62 structures called 'driver'. How about someone deciding
to prefix such a generic name with something specific to the actual
driver in question?
However, you can take a guess that it might be in IDE. Thankfully,
there aren't that many IDE drivers selected, so it's a choice of
three. If there were more, finding this would be a BIG problem.
Can we please change this silly policy of using stupidly generic names
like 'driver'?
In any case, this fixes the breakage. Referencing discarded exit
sections from .data sections is Bad News. And no, the kernels static
checker doesn't find this because 'driver' structures are exempted.
