Ingo, Thomas,

Please pull the timers/nohz-v3 branch that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	timers/nohz-v3

Changes since v2:

* Add Acks from Peter Zijlstra

* Only bother to fetch task's CPU if the task is queued in
	"tick/nohz: Kick only _queued_ task whose tick dependency is updated"
  (reported by Peter Zijlstra)

* Correctly indent comment in
  "tick/nohz: Kick only _queued_ task whose tick dependency is updated"
  (reported by Peter Zijlstra)

* Add Peter's SoB in "tick/nohz: Evaluate the CPU expression after the static key"

* Add "tick/nohz: Call tick_nohz_task_switch() with interrupts disabled"
  (from Peter Zijlstra)

* Add "MAINTAINERS: Add myself as context tracking maintainer"

---
Summary:

* Further reduce ticks and IPIs in full dynticks mode.

* Optimize static key based test for a CPU's nohz_full mode
  and also tick nohz probe on context switch.

* A few cleanups, Kconfig documentation and maintainership clarification.

HEAD: 380b68819eed62264ad8e54467481ca7003248c3

Thanks,
	Frederic
