Cover letter [PATCH] [0/7] Add noclflush option and related cleanup

I added a noclflush option because Ingo asked for it to make it possible to disable parts of the new CPA code.

While I was at it I did some generic cleanup in the area of cpuid disable options and generalized them a bit. That is where the other patches come from.
