And the reason that it built on 32-bit x86 was that I mistakenly
built only the RCU files, not the whole kernel.  So I am guessing
that there is something I need to merge into tip/smp/hotplug.

On the other hand, removing the __GFP_NOTRACE allows this patchset to
pass modest rcutorture testing on Power.  ;-)
