You have a knack for confusing changelogs.. so basically you say: Restart the tick when we switch to idle.Now all that needs is an explanation of why..Also, please drop the whole cpuset_nohz_ stuff, this really isn't aboutcpusets, cpusets simly provide the interface, the functionality lives inthe tick_nohz_ namespace.
