Hi Tony,

I'm having trouble replicating this error.  With the latest linux-2.6.git
plus the patch I just sent, I get the following errors:

drivers/input/mouse/psmouse-base.c:45: error: __param_proto causes a section type conflict
drivers/md/md.c:5881: error: __param_start_ro causes a section type conflict

(plenty of warnings too, but no vmlinux)

I copied arch/ia64/configs/tiger_defconfig to .config, ran menuconfig to
turn off SMP and built with this line:

make ARCH=ia64 CROSS_COMPILE=ia64-linux-gnu- -i -j10

Could this be a problem with:

#ifdef HAVE_MODEL_SMALL_ATTRIBUTE
# define PER_CPU_ATTRIBUTES     __attribute__((__model__ (__small__)))
#endif

This is only defined for !__ASSEMBLY__

Thanks,
Mike
