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
