linux64.ko fails to load in -CURRENT

[R. Tyler Croy]

I have noticed this over the past couple weeks with my -CURRENT laptop that
64-bit linux compatibility is failing to load, and I'm not entirely sure why.
My current kernel is based off of r321626.

When I run `kldload linux64` it fails with the following:

    link_elf_obj: symbol elf64_linux_vdso_fixup undefined
    linker_load_file: /boot/kernel/linux64.ko - unsupported file type


It's unclear to me whether this is old cruft sitting around, a regression, or
something else entirely floating around my system. Any pointer would help :)


Cheers
