I didn't look at this closely, but sounds like disabling vgacon on
microblaze made sound drivers fail because they or microblaze does not
enable something in the kernel config.

Looking at this shortly, the reason is that EXPORT_SYMBOL() of
isa_io_base is missing for microblaze. I don't know, though, why the
mentioned commit triggers the bug, too...

I think that the commit in question did not introduce the isa_io_base
link failer but rather revealed it in that the make process now proceeds
to the module linking phase.

>From the commit message in question:

Fix an allmodconfig link failer on microblaze:
drivers/built-in.o: In function `vgacon_save_screen':
drivers/video/console/.tmp_vgacon.o:(.text+0x8fc10):
undefined reference to `screen_info'

Thus, it seems to me, that before that commit, the linking of vmlinux
failed. AFAICT, module linking always comes after vmlinux has been built,
justifying my above statement.


In my opinion, the best thing to do here is simply to EXPORT_SYMBOL() the
isa_io_base as Takashi said.

Who sends a patch? Takashi, do you want to?
If you don't, I'd gladly do it.

Thanks,

Nicolai
