Hm, the first patch does not apply to tip:timers/core, as it conflicts
with:

fb82fe2fe858 clocksource: Add 'max_cycles' to 'struct clocksource'
362fde041037 clocksource: Simplify the logic around clocksource wrapping safety margins

Mind resending your latest queue as patches, on top of tip:timers/core
or tip:master?

Thanks,

Ingo
