Lots.

I restored the patches and just dropped the hunk:

  static int has_mm(struct task_struct *p)
  {
-       return (p->mm && !(p->flags & PF_BORROWED_MM));
  }
  
  /**
--- 86,92 ----
  
  static int has_mm(struct task_struct *p)
  {
+       return (p->mm && !(p->flags & PF_KTHREAD));
  }

due to that function having been turned into:

static inline bool should_send_signal(struct task_struct *p)
{
        return !(p->flags & PF_FREEZER_NOSIG);
}

Please check the result?
