2018-08-02tick/broadcast-hrtimer: Use cpu_possible_mask for ce_broadcast_hrtimerSudeep Holla
This is the last instance of cpu_all_mask usage in the core framework. Replace it with cpu_possible_mask like all other instances in the clockevent drivers. This makes it possible to add a warning in the core clockevents_register_device on usage of cpu_all_mask from any clockevent drivers in the future.

2018-08-02timers: Clear timer_base::must_forward_clk with timer_base::lock heldGaurav Kohli
timer_base::must_forward_clock is indicating that the base clock might be stale due to a long idle sleep. The forwarding of the base clock takes place in the timer softirq or when a timer is enqueued to a base which is idle. If the enqueue of timer to an idle base happens from a remote CPU, then the following race can happen: CPU0 CPU1 run_timer_softirq mod_timer base = lock_timer_base(timer); base->must_forward_clk = false if (base->must_forward_clk) forward(base); -> skipped enqueue_timer(base, timer, idx); -> idx is calculated high due to stale base unlock_timer_base(timer); base = lock_timer_base(timer); forward(base); The root cause is that timer_base::must_forward_clk is cleared outside the timer_base::lock held region, so the remote queuing CPU observes it as cleared, but the base clock is still stale. This can cause large granularity values for timers, i.e. the accuracy of the expiry time suffers. Prevent this by clearing the flag with timer_base::lock held, so that the forwarding takes place before the cleared flag is observable by a remote CPU.
