Ok.

I do not understand your meaning clearly.
Do you mean the follow-up patch ( XSTATE_XSAVES_ONLY derived from cpuid)
will not into 4.7 ? If so, when is best/proper time to send out the
follow-up patch ? I am not sure whether add the follow-up patch in this 
patchset or in a sperate patch which one is ok ?
In either case I will keep working on this.
