Anything using symbol_get is by intent very deeply internal for tightly
coupled modules working together, and thus not a non-GPL export.

In fact the current series is just a stepping stone.  Once some mess
in the kvm/vfio integration is fixed up we'll require a new explicit
EXPORT_SYMBOL variant as symbol_get wasn't ever intended to be used
on totally random symbols not exported for use by symbol_get.
