This little recidivist is still using gcc-2.91.66.  It is not
placing the percpu data in the correct section.  It is not 
entirely obvious why.

I downgraded to 2.95.3 (build time went from 2:45 to 3:15, giving
nothing in return) and Brian's patch worked OK.

ho hum.  So.  2.91.66, rest in peace.  I shall miss you.
