  [i915_bpo] Sync to v4.2.2

Status in linux package in Ubuntu:

  In Progress

Bug description:
  There are a few bugfixes upstream that our backport lacks:

   drm/i915: Fix CSR MMIO address check
   drm/i915: Limit the number of loops for reading a split 64bit register
   drm/i915: Always mark the object as dirty when used by the GPU
   drm/i915: Allow DSI dual link to be configured on any pipe
   drm/i915: Preserve SSC earlier
   drm/i915: Check DP link status on long hpd too

  the bottom one fixes one OEM bug which also got a BIOS workaround, but
  a code fix would be in order for other platforms.

As it's a test Kernel testing, I will invalid this issue but leave the

Bug description:
  There are a few bugfixes upstream that our backport lacks:

   drm/i915: Fix CSR MMIO address check
   drm/i915: Limit the number of loops for reading a split 64bit register
   drm/i915: Always mark the object as dirty when used by the GPU
   drm/i915: Allow DSI dual link to be configured on any pipe
   drm/i915: Preserve SSC earlier
   drm/i915: Check DP link status on long hpd too

  the bottom one fixes one OEM bug which also got a BIOS workaround, but
  a code fix would be in order for other platforms.

[Vanessa Chang]

Verified Passed below by KH0916-0 build with proposed kernel 3.19.0-29

- Screen can be passed with rotation test
- Switch to VT and logging out does not cause flicker

  [BDW] VGA output regression on 4.2 (was: Migrate Broadwell to use
  i915_bpo)

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Vivid:
  Fix Committed

Bug description:
  There are several bugs affecting Broadwell generation graphics in the
  vivid kernel (3.19), but not found in 4.2rc which i915_bpo module is
  based on. In order to support our OEM partners (and other BDW users)
  it would make sense to migrate BDW to use i915_bpo instead.

  The known (public) bugs this would fix are:

  - screen is black after xrandr rotate command
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1446979

  - changing the VT causes flicker
  https://bugs.freedesktop.org/show_bug.cgi?id=85583
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1450557

  - GPU hangs on resume
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1468232
  (and dupes, which I believe there are several of)

  - and some OEM machines can't always hotplug the HDMI output (no
  public bug AIUI)

  the migration should not be too risky, since i915_bpo is already used
  for Braswell which is same generation as (=based on) BDW.

Bug description:
  This is a long-standing bug for some Haswell, Broadwell and most

  When the HDA audio controller is in D3, a hotplug event (i e, HDMI or

  never registers that something has happened.

  By having the i915 driver call directly into the hda driver, the HDA
