Let's do that.

You should be pretty aware of 95d6c0857e54b788982746071130d822a795026b ;)

Depending if we have or not this patch, intel_pstate engage itself or not.

When engaged, we have to perform some configuration that the other state
doesn't imply.


I'm updating the patch this way than send a v6.

I just let intel_pstate_msrs_not_valid() in pr_warn() as this one is not
supposed to be a "normal" case.


Thanks for your time & reviews.

My pleasure !

Erwan,
