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.
