drm/exynos: fix size check in g2d_check_buf_desc_is_valid()
The size check was incomplete. It only computed the
size of area of the drawing rectangle and checked if
the size still fit inside the buffer.
The correct check is to compute the position of the
last byte that the G2D engine is going to access and
then check if that position is still contained in the
buffer. In particular we need the stride information
to determine this.
The DP MST encoder config function never sets ddi_pll_sel, even though
its value is programmed in its ->pre_enable() hook. That used to work
because a new pipe_config was kzalloc'ed at every modeset, and the value
of zero selects the highest clock for the PLL. Starting with the commit
below, the value of ddi_pll_sel is preserved through modesets, and since
the correct value wasn't properly setup by the MST code, it could lead
to warnings and blank screens.

Commit 92122789b2d6 ("drm/i915: preserve SSC if previously set v3")
added code to intel_modeset_gem_init to override the SSC status read
from VBT with the SSC status set by BIOS.
However, intel_modeset_gem_init is invoked *after* intel_modeset_init,
which calls intel_setup_outputs, which *modifies* SSC status by way of
intel_init_pch_refclk. So unlike advertised, intel_modeset_gem_init
doesn't preserve the SSC status set by BIOS but whatever
intel_init_pch_refclk decided on.
This is a problem on dual gpu laptops such as the MacBook Pro which
require either a handler to switch DDC lines, or the discrete gpu
to proxy DDC/AUX communication: Both the handler and the discrete
gpu may initialize after the i915 driver, and consequently, an LVDS
connector may initially seem disconnected and the SSC therefore
is disabled by intel_init_pch_refclk, but on reprobe the connector
may turn out to be connected and the SSC must then be enabled.
Due to 92122789b2d6 however, the SSC is not enabled on reprobe since
it is assumed BIOS disabled it while in fact it was disabled by
intel_init_pch_refclk.
Also, because the SSC status is preserved so late, the preserved value
only ever gets used on resume but not on panel initialization:
intel_modeset_init calls intel_init_display which indirectly calls
intel_panel_use_ssc via multiple subroutines, *before* the BIOS value
overrides the VBT value in intel_modeset_gem_init (intel_panel_use_ssc
is the sole user of dev_priv->vbt.lvds_use_ssc).
Fix this by moving the code introduced by 92122789b2d6 from
intel_modeset_gem_init to intel_modeset_init before the invocation
of intel_setup_outputs and intel_init_display.

Merge branch 'linux-4.3' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
Rather large pull request this time around, due to the long-pending
cleanup of the kernel driver being here. There's a stupidly large
number of commits for that, as I wanted to have the series be
bisectable at a fairly fine-grained level. That said, a very large
portion of the churn in the rework was automated, and a very large
number of boards from right across the whole range we support have
been tested. I'm fairly confident there shouldn't be (too many)
issues from this.
Beyond correcting some not-so-great design decisions and making the
code a lot easier to work with, there's not much exciting (lower
memory usage, GPU VM should be a lot faster, etc) to be gained by the
end-user as a result of the cleanup, it mostly lays the groundwork for
future improvements.
A big thanks goes to Alexandre Courbot for testing/debugging the GK20A
codepaths for me :)
Highlights:
- A heap of perfmon work, providing a more useful userspace interface
and specifying counters for a bunch of boards
- Support for GT200 reclocking + other misc pm improvements
- Initial patches towards supporting GM20B (Tegra X1)
- Maxwell DisplayPort fixes
- Cleanup of the kernel driver
- The usual collection of random fixes

drm/nouveau/tegra: merge platform setup from nouveau drm
The copyright header in nvkm/engine/device/platform.c has been replaced
with the NVIDIA one from drm/nouveau_platform.c, as most of the actual
