The patch "sched: cpuacct: Use bigger percpu counter batch values for stats
counters" in tip (43f85eab1411905afe5db510fbf9841b516e7e6a) would fail to
build without this if CONFIG_SMP is not set.

Thanks

Which is why it got reverted (e2dfc8a0356ee7e065bd5ec8a2ca0f9b61c2daef),
Anton also posted a new version that actually does build on UP.
