_mmx_memcpy and module symbol versioning in 2.4.x
It seems that _mmx_memcpy is exported incorrectly in 2.4.x kernels if module symbol versioning is turned on - modules that use it fail to load and tell that the function is undefined; /proc/ksyms shows the versioned name as _mmx_memcpy_R__ver__mmx_memcpy (so that __ver__mmx_memcpy remains undefined during kernel compilation).
It seems that the problem appeared in 2.4.0 -

I experience it on 2.4.19 . Problem appears when kernel is compiled with CONFIG_MODVERSIONS=y and CONFIG_MK7=y
