Merge branch 'timers/nohz-for-tip' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks into timers/nohz

Pull NOHZ updates from Frederic Weisbecker:

  - Fix some jiffies based cputime assumptions. No real harm because the
    concerned code isn't used by full dynticks.

  - Simplify jiffies <-> usecs conversions. Remove dead code.

  - Remove early hacks on nohz full code that avoided messing up idle
    nohz internals. Now nohz integrates well full and idle and such hack
    have become needless.

  - Restart nohz full tick from irq exit. A simplification and a
    preparation for future optimization on scheduler kick to nohz full.

  - Simple code cleanups.

  - Tile driver isolation enhancement on top of nohz.
