And yet x86_64 has this code implemented in assembly even in the
slowpath.  Go figure.

There is way too much assembly in entry_64.S probably because things
have been grafted on, ahem, "organically".  It is darn nigh impossible
to even remotely figure out what goes on in that file.

Always warn your family and give them an estimate return hour before opening that file.
