loop-aes 3.2b and AMD64_ASM build problem

[Thorsten Peter <thorsten.peter@xxxxxxxxxxxxxx>]

Hey all,

I have been trying to build latest loop-aes from source today on my 
AMD64 (Athlon 64 3000+) machine today and ran into these errors:

$ make AMD64_ASM=y X86_ASM=n
rm -r -f *.ko tmp-d-kbuild
mkdir tmp-d-kbuild
echo 'obj-m:=' >>tmp-d-kbuild/Makefile
cd tmp-d-kbuild && ln -s ../loop.c-2.6.patched patched-loop.c && ln -s 
../glue.c ../aes.h ../md5.h .
echo 'obj-m += loop.o' >>tmp-d-kbuild/Makefile
cd tmp-d-kbuild && ln -s ../aes-amd64.S ../md5-amd64.S .
echo 'loop-y:=patched-loop.o glue.o aes-amd64.o md5-amd64.o' 
>>tmp-d-kbuild/Makefile
echo 'EXTRA_CFLAGS:=      -DAMD64_ASM' >>tmp-d-kbuild/Makefile

Build was started using:

make X86_ASM=n AMD64_ASM=y

Without giving those command line parameters build uses the X86 config, 
though my kernel (2.6.23.1) is configured for Athlon K8 in Processor 
Type and Features.

Anyone here using loop-aes with those AMD64 optimizations?

thanks for any help.

Thorsten
