Ingo, Thomas,
This starts the basic code that allow accounting of cputime spent tickless
outside idle, which is a first step to prepare for the adaptive nohz
infrastructure.
I hope we can set a tree in -tip for that. If you're fine with it
this is pullable from:
git://github.com/fweisbec/linux-dynticks.git
nohz-for-tip
Thanks.
