64-bit args are passed as a pair of 32-bit args, so PAE set_pte_at*
functions end up with 5 args. They're used often, so they may be worth
patching, but I'm not sure if they're worth exporting. They are
implicitly exported in a non-PARAVIRT build by the fact that they're
inline functions/macros in a header. I don't know if any modules
actually use them.
