Looks sane, and makes sense. I feel that the old "mixed C and asm" was
much worse.

My only comment is that I think you should remove the ENTRY() one,
because you don't actually want that symbol to be global any more,
because I think it's all from inside copy_user_64.S now.

So just

     ALIGN
     copy_user_handle_tail:
          .. code goes here..

Hmm?
