Since tip:timers/nohz only contains these commits:

 fc1781cc66b1 Merge branch 'timers/nohz-ipi-for-tip-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks into timers/nohz
 72aacf0259bb nohz: Move full nohz kick to its own IPI
 55d77c215c74 smp: Non busy-waiting IPI queue

we can zap them all, or even keep 55d77c215c74.

Frederic, which one would you prefer?

Thanks,

	Ingo
