[PATCH 0/5] [Maverick] SRU: Restore video from S3 resume on Sandybridge

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

BugLink: http://launchpad.net/bugs/663442

SRU Justification:
 
Impact: Resuming from S3 on Sandybridge laptops results in a blank display
and no video.

Fix: Attached 5 patches restore fence registers correctly, align the display
surface so to avoid tiling corruption and correctly check for sandybrige
chipset in resume path.

Testcase: Without the patches, resume from S3 results in a blank display with
no video being displayed. With the patches, S3 can be run multiple times and
video is restored correctly on each resume.

Chris Wilson (5):
  drm/i915: Silence sparse over duplicate members in static initializer
  drm/i915: Use 128k alignment for untiled display surface on i965 (v2)
  drm/i915: Include a generation number in the device info
  drm/i915: Fix Sandybridge fence registers
