No. I'm referring to in tree archs which do not use the clock events at all yet. The MIGR symbol allows them to do a step by step conversion which builds the generic clock events stuff first before switching over to use them. That's why it was created in the first place and it has been proven useful when doing such work. So I'd rather see it stay until all archs actually use the generic framework. But yes, we can apply your patch and just let them select GENERIC_CLOCKEVENTS_BUILD instead. Thanks, tglx
