Oh, wait, no, I remember: the reason it's not a separate patch is
that stack_user is statically initialized, so next == 0 never
occurred.  But, changing it to __stack_user changed how it has to
be initialized, so next == 0 can now occur.

So it should be the same patch (but maybe it needs documenting!)

Cheers,
Gary
