I had been wondering about that.  You've convinced me.  It now reads:

    This bug was introduced in 3.1 and is suitable for any stable kernels
    from then onwards.
    As the offending commit was tagged for 'stable', any stable kernel
    that it was applied to should also get this patch.  That includes
    at least 2.6.32, 2.6.33 and 3.0. (Thanks to Ben Hutchings for
    providing that list).

Thanks,
NeilBrown
