And exactly this change wants to be a separate patch. We do not make whole
sale changes this way. You should know that already and someone pointed
that out to you in some of the earlier versions.

The function name sucks. The first time I read it, it meant request the per
cpu irq flags, which is not what you aim at, right?

Please make that __request_percpu_irq() for now and on -rc1 time provide a
patch set to convert all current request_percpu_irq() users to have the
extra argument and then remove the __request_percpu_irq() intermediate.

Thanks,
