H A Dtypes.hdiff 468d01be Thu Feb 02 12:40:15 MST 2017 Paul E. McKenney <paulmck@kernel.org> types: Update obsolete callback_head comment

The comment header for callback_head (and thus for rcu_head) states that
the bottom two bits of a pointer to these structures must be zero. This
is obsolete: The new requirement is that only the bottom bit need be
zero. This commit therefore updates this comment.
