Cover letter [PATCH 00/12] Broadwell 3.14 backports

The following patches are the backported "simple" fixes for 3.14. Some of these already had Cc: stable on them, but required conflict resolution which I've provided (presumably they canbe dropped if it's easier for upstream). There will be another series of backports which has fixes that require more than a single patch.

I will not have a machine to test these on until Monday, but I am mailing them out now in case our QA can get it tested sooner.
