[Trusty][PULL]: ubuntu/i915 rebase to v3.16

[Timo Aaltonen]

	Hi,

  Here we go again, hopefully for the last time for this kernel.. 

git://kernel.ubuntu.com/tjaalton/ubuntu-trusty.git i915-bdw

The branch rebases i915_bdw backport driver to v3.16, pulling some core drm changes again which only add new features for this driver, not changing original v3.13 drivers. Some drm churn got reverted from the driver instead. There are 41 commits in total, but it's not that scary, really :) 

More detailed explanations of the commits:

- backport aid

786ba57a36209fc ACPI / i915: ignore firmware requests for backlight change
- this could be avoided, but is actually useful to have backported anyway

1f012b75bb6eae8 drm/i915: Kick out vga console

- the backport needs these exported

- revert smaller and some bigger changes from the driver, still manageable


I guess there will be comments :)
