---Summary---
Mainstream Intel processors have been using Family 6 for a couple of decades.
This series is an audit of all the arch/x86 Intel Family-model checks to get
ready for the upcoming Family 18 and 19 models. It also converts the last
reamaining Intel x86_model checks to VFM ones.

Patch 1-8 : Include Dave Hansen's Acked-by.
Patch 9-15: Almost ready to merge but don't have review tags yet.

---v3 changes---
* Reordered the patches and moved the Acked ones to the front since they are
  likely to get applied sooner.
* Patches 11 and 14 have a slightly different approach now. 
* Improved commit messages overall.
* Dropped the drivers/ fixes. Will post them separately.

---Previous versions---
Refer the v2 cover letter for more background.
