Good question. The current systems which are commercial, already have
cpuid added in our list, so HWP will be enabled anyway.
The one system we know there is an issue, hope we can debug before
merge window start.
If I don't do, I have to add few more ids to the list.
Let's wait for few more weeks to review and merge this. I will let
anybody from the community comment, who are using Skylake.
Thanks,
Srinivas
