Merge tag 'timers-v6.11-rc7' of https://git.linaro.org/people/daniel.lezcano/linux into timers/urgent
Pull clocksource driver fixes from Daniel Lezcano:
- Remove percpu irq related code in the timer-of initialization
routine as it is broken but also unused (Daniel Lezcano)
- Fix return -ETIME when delta exceeds INT_MAX and the next event not
taking effect sometimes (Jacky Bai)
