fixup for drm/i915: Add vma to list at creation
Since the active/inactive lists are per VM, we need to modify the error
capture code to be aware of this, and also extend it to capture the
buffers from all the VMs. For now all the code assumes only 1 VM, but it
will become more generic over the next few patches.
NOTE: If the number of VMs in a real world system grows significantly
we'll have to focus on only capturing the guilty VM, or else it's likely
there won't be enough space for error capture.

The mm_list is used for the active/inactive LRUs. Since those LRUs are
per address space, the link should be per VMx .
Because we'll only ever have 1 VMA before this point, it's not incorrect
to defer this change until this point in the patch series, and doing it
here makes the change much easier to understand.
Shamelessly manipulated out of Daniel:
"active/inactive stuff is used by eviction when we run out of address
space, so needs to be per-vma and per-address space. Bound/unbound otoh
is used by the shrinker which only cares about the amount of memory used
and not one bit about in which address space this memory is all used in.
Of course to actual kick out an object we need to unbind it from every
address space, but for that we have the per-object list of vmas."

drm/i915/hsw: Set correct Haswell PTE encodings.
On the surface it would seem setting a default age wouldn't matter
because all GEM BOs are aged similarly, so the order in which objects
are evicted would not be subject to aging. The current working theory as
to why this caused a regression though is that LLC is a bit special in
that it is shared with the CPU. Presumably (not verified) the CPU
fetches cachelines with age 3, and therefore recently cached GPU objects
would be evicted before similar CPU object first when the LLC is full.
It stands to reason therefore that this would negatively impact CPU
bound benchmarks - but those seem to be low on the priority list.
eLLC OTOH does not have this same property as LLC. It should be used
entirely for the GPU, and so the age really shouldn't matter.
Furthermore, we have no evidence to suggest one is better than another
on eLLC. Since we've never properly supported eLLC before no, there
should be no regression. If the GPU client really wants "younger"
objects, they should use MOCS.

Get rid of the WARN by making the polarity setting explicit in the

drm/i915: clean up crtc timings computation
In the old days of the crtc helpers we've only had the encoder and
crtc ->mode_fixup callbacks. So when the lvds connector wanted to
adjust the crtc timings it had to set a driver-private mode flag to
tell the crtc mode fixup code to not overwrite them with the generic
ones.
When converting things to the new infrastructure I've kept the entire
logic and only moved the flag to pipe_config->timings_set. But this
logic is pretty tricky and already caused regressions:
drm/i915: fix pfit regression for non-autoscaled resolutions
So take advantage of the flexibility our own modeset infrastructure
affords us and prefill default crtc timings. This allows us to rip out
->timings_set. Note that we overwrite things again when retrying the
pipe config computation due to bandwidth constraints to avoid bogus
crtc timings if the encoder only does relative adjustments (which is
how the pfit code works). Only a theoretical concern though since
platforms where we retry (pch-split platforms) do not need
adjustements (since only the old gmch pfit needs that). But let's
better be safe than sorry.
Since we now initialize the crtc timings before calling the
encoder->compute_config functions the crtc initialization in the gmch
pfit code is now redudant and so can be removed.
