Except for a bunch of constants defined there. Are you sure that they
are not exposed to userland?

A userspace program that has OSS ac97 specific code?
I didn't find one.

BTW: OSS and ALSA managed to give different names to several of these
constants...

Such relative includes should be avoided. Set CFLAGS_xxx.o in Makefile instead.
And move include down under #include <asm/xxx>

OSS never really exposed raw AC97 to user space. Probably it should have
for the whacky corner cases and for stuff like AC97 digitizers.

The reason why ac97_codec.h is in include/linux is because it provides a
__public interface__.
Adrian's change
(a) makes it difficult to work on OSS drivers outside sound/oss
(b) increases the pain level of keeping 2.4 and 2.6 drivers in sync --
something that I am doing to i810_audio at least.
ac97_codec.h should stay where it is, until OSS drivers are removed from
the tree.
