Pull timer fixes from Thomas Gleixner: "This update brings along: - Two fixes for long standing bugs in the hrtimer code, one which prevents remote enqueuing and the other preventing arbitrary delays after a interrupt hang was detected - A fix in the timer wheel which prevents math overflow - A fix for a long standing issue with the architected ARM timer related to the C3STOP mechanism. - A trivial compile fix for nspire SoC clocksource" * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: timer: Prevent overflow in apply_slack hrtimer: Prevent remote enqueue of leftmost timers hrtimer: Prevent all reprogramming if hang detected clocksource: nspire: Fix compiler warning clocksource: arch_arm_timer: Fix age-old arch timer C3STOP detection issue
