Two fairly useful bug fixes:

* Quirk for Lenovo U160 to prevent a black-screen when KMS starts up.
  We've gone round and round trying to make this hardware 'just work',
  it's time to give up and special case this box.

* Fix longstanding regression on old (pre-G33) hardware with tiled
  buffer alignment.

A few regression fixes:

 * eDP panels with too few lanes need 6bpc modes
 * older machine backlights going black
 * divide-by-zero crash when reading a /sys file

Quirks for a couple of machines:

 * No lvds panel on a desktop ASUS machine
 * Light up the second LVDS on the Libretto W105

Two more Ivybridge changes:

 * Use Multi-threaded force-wake where enabled by the BIOS
 * Light up eDP panels

Finally, this enables RC6 and semaphores, unconditionally on Ivybridge.
On Sandybridge, these are enabled when VTd isn't in use. We've been
wanting to do this for a long time, and instead of turning this on for
RC1 and hoping things worked out, we spent time working directly with
people who reported problems and discovered that RC6 and Semaphores
cannot be enabled when VTd is in use (even VTd for non-gfx devices).

There's a patch here which exports a value from the iommu code letting
us know when VTd is active so that RC6 and semaphores can be
disabled. That patch has been ok'd by David Woodhouse, although he's not
very happy about it. Matthew Garrett wanted to write a second patch that
disabled VTd by default on SNB machines, which would enable RC6 and
semaphores more often.

Two bug fixes, a new platform backlight driver and a bit of debug output
for IVB interrupts:

 * Dual-display mode setting manipulations on SNB machines would sometimes
   accidentally turn off all outputs.

 * Attempts to use UMS would segfault in the kernel and generate a pile
   of spurious kernel diagnostics. Detecting a few more KMS-only
   features in the general paths fixes this.

 * Expose a native backlight driver for machines that don't bother to
   have suitable platform or ACPI drivers.

 * Share an SNB interrupt debug function for IVB.

      drm/i915: Cannot set clock gating under UMS

Matthew Garrett (1):
      Not all systems expose a firmware or platform mechanism for changing the backlight intensity on i915, so add native driver support.

What have we got here: 

 * A list of DP fixes from Jesse to make the code conform more closely
   to the specification.

 * Making Ivybridge use the Sandybridge GPU reset path.

 * Recover from i915 load failure without causing a later panic
   when the shrinker ran.

 * Revert the RC6 enable patch -- there are at least two machines which
   mysteriously fail with RC6 enabled. We found lots of possible causes,
   none of which appear to help these last few hold-outs.

 * Fix an obvious typo -- the GPU idling code was using the wrong variable
   for the size of the ring. This may well cause spurious suspend
   failures as the GPU wouldn't have been reliably idled.

Another forcewake fix, a NULL pointer oops, some error-path cleanups, a
UMS for IRL fix and another IVB fix. The UMS for IRL fix (from Jesse)
contains a bunch of code motion, hence the fairly large
diffstat. Otherwise, these are all tiny fixes.
