[RFC GIT PULL] nohz: Basic cputime accounting for adaptive tickless

[Frederic Weisbecker]

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:

Thanks.
