test13-preX: DRM (tdfx.o) unresolved symbols fixed?

[Dieter Nützel]

Hello to all of you,

I got this since test13-pre1 (pre4, now):

SunWave1>depmod -e
depmod: *** Unresolved symbols in 
/lib/modules/2.4.0-test13-pre4/kernel/drivers/char/drm/tdfx.o

Something missing in the 'new' drm/Makefile?

If I do `nm tdfx.o|grep printk`, with test12 I get only this:

         U printk_R1b7d4074

with test13-pre4 on my home machine, I get the mangled symbol name plus a
non-mangled one, both unresolved, maybe that causes problems.

Yep, I saw this, too.

dito
SunWave1>cd ../../../../../2.4.0-test12-pre7/kernel/drivers/char/drm/
SunWave1>nm tdfx.o | grep printk
         U printk_R1b7d4074

SunWave1>cd ../../../../../2.4.0-test13-pre4/kernel/drivers/char/drm/
SunWave1>nm tdfx.o | grep printk
         U printk
         U printk_R1b7d4074

But the strange thing is this:

SunWave1>depmod -e
depmod: *** Unresolved symbols in 
/lib/modules/2.4.0-test13-pre4/kernel/drivers/char/drm/tdfx.o
depmod:         remap_page_range
depmod:         _mmx_memcpy
depmod:         __wake_up
depmod:         mtrr_add
depmod:         __generic_copy_from_user
depmod:         schedule

If I compile agpgart and tdfx directly into the kernel, it works for me, too.

Thanks!
