CFT: drm/i915 update to Linux 3.11

[Francois Tigeot]

Hi,

I have updated the drm/i915 driver to its Linux 3.11 version.

It is available from this git branch on leaf:
http://gitweb.dragonflybsd.org/~ftigeot/dragonfly.git/shortlog/refs/heads/drm_i915_linux_3_11_rebased

Or as a small series of patches to be applied with git am:
http://dl.wolfpond.org/drm_i915_linux_3_11/

The code requires a very recent version of master and a full buildkernel.

It would be nice if this could be tested on a wide range of hardware.
