I think this error showed up the first time that the sysdev removal stuff
was included in linux-next i.e. after the other errors/warnings had been
dealt with.

The tracing code is obscure and I suspect that there may be some ordering
issue in there. What seems to have triggered this is the include of
device.h instead of sysdev.h in cpu.h. This has caused a whole lot more
tracepoints(?) to be defined.
So it is a side effect and needs the tracing guys to track it down :-(
