For some strange reason I had RCU_TORTURE_TEST defined in my config. This
caused my compile to blow up because kernel/rcu/rcutorture.c wanted to test the
(now ifdef'ed out) rcu_bh routines. This fixes the compile issue but is
untested for actually *running* rcutorture. I'll try that on a test box
tomorrow.
