ah, that's Peter's stuff:
4cd4c1b: timers: split process wide cpu clocks/timers
32bd671: signal: re-add dead task accumulation stats.
The discussion with Oleg resulted in the conclusion i
think that the warning is spurious and should be removed.
I've commited the minimal fix below to tip:master. There's
more fixes needed too but this should solve the warning
flood at least.
