Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer updates from Ingo Molnar: "The main changes in this cycle were: - clockevents state machine cleanups and enhancements (Viresh Kumar) - clockevents broadcast notifier horror to state machine conversion and related cleanups (Thomas Gleixner, Rafael J Wysocki) - clocksource and timekeeping core updates (John Stultz) - clocksource driver updates and fixes (Ben Dooks, Dmitry Osipenko, Hans de Goede, Laurent Pinchart, Maxime Ripard, Xunlei Pang) - y2038 fixes (Xunlei Pang, John Stultz) - NMI-safe ktime_get_raw_fast() and general refactoring of the clock code, in preparation to perf's per event clock ID support (Peter Zijlstra) - generic sched/clock fixes, optimizations and cleanups (Daniel Thompson) - clockevents cpu_down() race fix (Preeti U Murthy)" * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (94 commits) timers/PM: Drop unnecessary braces from tick_freeze() timers/PM: Fix up tick_unfreeze() timekeeping: Get rid of stale comment clockevents: Cleanup dead cpu explicitely clockevents: Make tick handover explicit clockevents: Remove broadcast oneshot control leftovers sched/idle: Use explicit broadcast oneshot control function ARM: Tegra: Use explicit broadcast oneshot control function ARM: OMAP: Use explicit broadcast oneshot control function intel_idle: Use explicit broadcast oneshot control function ACPI/idle: Use explicit broadcast control function ACPI/PAD: Use explicit broadcast oneshot control function x86/amd/idle, clockevents: Use explicit broadcast oneshot control functions clockevents: Provide explicit broadcast oneshot control functions clockevents: Remove the broadcast control leftovers ARM: OMAP: Use explicit broadcast control function intel_idle: Use explicit broadcast control function cpuidle: Use explicit broadcast control function ACPI/processor: Use explicit broadcast control function ACPI/PAD: Use explicit broadcast control function ...
