It looks like it is caused by 6e2ca7d1802bf8ed9908435e34daa116662e7790 and sticking uninitialized_var() around the ptep_user declaration looks like the easiest solution. But the code should still be audited by someone who's familiar with it whether shutting up the compiler doesn't cause an actual bug.
