I guess that a part of the answer stands there:

http://cvs.parisc-linux.org/linux-2.5/include/asm-parisc/Attic/gsc.h
Revision 1.5 , Fri Nov 1 01:04:30 2002 UTC (8 months, 1 week ago) by willy
Move gsc_read,write[bwl] to asm/io.h.  Move drivers/parisc/busdevice.h
to drivers/parisc/gsc.h.  Move the rest of include/asm-parisc/gsc.h
to drivers/parisc/gsc.h.  Edit dozens of files to remove the include
of <asm/gsc.h>

I tried to reproduce, correcting the path to gsc.h, and here's what
happened:

  CC      sound/parisc/harmony.o
sound/parisc/harmony.c: In function `snd_card_harmony_playback_open':
sound/parisc/harmony.c:712: structure has no member named `dma_private'

sound/parisc/harmony.c: At top level:
include/sound/initval.h:140: warning: `get_id' defined but not used
make[2]:***[sound/parisc/harmony.o] Error 1

Since I've not closely followed the last change made to 2.5, I cannot tell
right now what's wrong. Maybe willy can give us some hints there? ;)
Laurent Canet, which is the author of this driver, is currently on
vacation (as I'm supposed to be, btw ;P) so don't expect any help from him
before a little while.

I'll have a closer look and try to find out what's wrong.
