Athlon + Athlon optimized kernel => _mmx_mmcpy problems

Athlon + Athlon optimized kernel => _mmx_mmcpy problems

[Clemens Schwaighofer]

Hi,

I thought, as I have an Athlon, I should recompile my 2.4.18-ac3 kernel 
for Athlon optimzied ... yadda ... but this causes serious problems.

After booting, it has quite a lot of depmod problems, with depmod -e it 
shows all are '_mmx_mmcpy' and vmware can't compile, cause of the same 
error.

so I had to go back to PIII style ... or I wouldn't have been able to 
update vmware ... sad thing

I had this same problem untill I did a make mrproper and re-built from
scratch.  Some part of the build system seems to be the problem (make clean
does not help)

Known problem. Arch and SMP changes are not handled right. This is fixed
in kbuild 2.5 but that isnt merged into 2.4 (and probably wont be) or 
2.5 (where some of the ideas seem to be getting in bit by bit)
