f4b4718b61 drm: ast,cirrus,mgag200: use drm_can_sleep
these 3 were checking in_interrupt but we have situations where
calling vunmap under this could cause a BUG to be hit in
smp_call_function_many. Use the drm_can_sleep macro instead,
which should stop this path from been taken in this case.

ec14ba4779 drm/i915: Fix the offset issue for the stolen GEM objects
The 'offset' field of the 'scatterlist' structure was wrongly
programmed with the offset value from the base of stolen area,
whereas this field indicates the offset from where the interested
data starts within the first PAGE pointed to by 'scattterlist'
structure. As a result when a new GEM object allocated from stolen
area is mapped to GTT, it could lead to an overwrite of GTT entries
as the page count calculation will go wrong, refer the function
'sg_page_count'.

v2: Modified the commit message. (Chris)

372fbb8e39 drm/i915: Decouple GPU error reporting from ring initialisation
Currently we report through our error state only the rings that have
been initialised (as detected by ring->obj). This check is done after
the GPU reset and ring re-initialisation, which means that the software
state may not be the same as when we captured the hardware error and we
may not print out any of the vital information for debugging the hang.

This (and the implied object leak) is a regression from

    drm/i915: Do a fuller init after reset

Note that we are already starting to get bug reports with incomplete
error states from 3.13, which also hampers debugging userspace driver
issues.

v2: Prevent a NULL dereference on 830gm/845g after a GPU reset where
    the scratch obj may be NULL.

85ba7b7d39 Revert "drm/i915: Mask reserved bits in display/sprite address registers"
This reverts commit 446f254566.

I've left the masking in the pageflip code since that seems to be some
useful piece of preemptive robustness.

Iirc I've merged this patch under the assumption that the BIOS leaves
some random gunk in the lower bits and gets unhappy if we trample on
them. We have quite a few case like this, so this made sense.

Now I've just learned that there's actual hardware features bits in
the low 12 bits, and the kernel needs to preserve them to allow a
userspace blob to do its job. Given Dave Airlie's clear stance on
userspace blob drivers I've quickly chatted with him and he doesn't
seem too happy. So let's revert this.

If there are indeed bits that we must preserve in this range then we
can ressurrect this patch, but with proper documentation for those
bits supplied. And we probably also need to think a bit about
interactions with our driver.

13411ddd31 drm/tegra: Obtain head number from DT
The head number of a given display controller is fixed in hardware and
required to program outputs appropriately. Relying on the driver probe
order to determine this number will not work, since that could yield a
situation where the second head was probed first and would be assigned
head number 0 instead of 1.

By explicitly specifying the head number in the device tree, it is no
longer necessary to rely on these assumptions. As a fallback, if the
property isn't available, derive the head number from the display
controller node's position in the device tree. That's somewhat more
reliable than the previous default but not a proper solution.

7f39e59772 drm/nve0/fb/gddr5: more 10f200 stuff
Seen on Titan.  NFI what the condition to switch this on is yet, and,
hardcoding it to on currently causes master to report unknown intr
with a mask of 0x08002000.

b655f2bb77 drm/nve0/fb/gddr5: parse bios data into struct rather than using directly
Still essentially a struct of magic values with magic names and unknown
purposes.  But, we will shortly need to be able to mix and match bits of
the previous and next configurations to do a transition reclock, as such,
we can no longer directly use the vbios data with any ease.

This is probably nicer anyway in the long run, for a few reasons.
