Good point - i'll wait for v2. Or would you like to carry them in 
your kernel-doc tree?

This bit:

 include/trace/events/irq.h            |   46 ++++++++++++++++++++++++++++++---

Has changed in the tracing tree so it's probably better to carry it 
there - once your review feedback has been addressed and once your 
Acked-by is propagated into the patches.

Thanks,
