Add percpu_rwsem_release() and percpu_rwsem_acquire() for the users which need to return to userspace with percpu-rwsem lock held and/or pass the ownership to another thread. TODO: change percpu_rwsem_release() to use rwsem_clear_owner(). We can either fold kernel/locking/rwsem.h into include/linux/rwsem.h, or add the non-inline percpu_rwsem_clear_owner().
