That's not a proper description of the problem and the solution. The 
same problem of lack of proper explanation permeates most of your 
patches as well and that's very far from the quality threshold that 
core IRQ patches need to meet.

Crappy descriptions and passive-aggressive responses where you pretend 
you don't understand our complaints and just minimally address the 
problems are not acceptable.

So I concur with Thomas and this series earns a big fat NAK from me. 
(Please Cc: me to all (if any) future resubmissions so I can track 
progress (or the lack thereof) and see whether I can lift my NAK.)

Thanks,
