5255e2f8d1 drm/i915: Replace vbt edp.support with int_lvds_support 
Replace dev_priv->vbt.edp.support with
dev_priv->vbt.int_lvds_support. We'll want to extend its
use beyond the LVDS vs. eDP case in the future.

v2: Nuke the edp.support from parse_edp() (Jani)
    Only clear int_lvds_support for gen5+ to preserve
    the current behaviour (Jani)

1abb70f595 drm/i915/gtt: Allow pagedirectory allocations to fail 
As we handle the allocation failure of the page directory and tables by
propagating the failure back to userspace, allow it to fail if direct
reclaim is unable to satisfy the request (i.e. disable the oomkiller).
The premise being that if we are unable to allocate a single page for
the pagetable, we will not be able to handle the multitude of pages
required for the gfx operation and we should back off to allow the
system to recover.

d93fa1b47b Revert "drm/i915/edp: Allow alternate fixed mode for eDP if available." 
This reverts commit dc911f5bd8.

Per the report, no matter what display mode you select with xrandr, the
i915 driver will always select the alternate fixed mode. For the
reporter this means that the display will always run at 40Hz which is
quite annoying. This may be due to the mode comparison.

But there are some other potential issues. The choice of alt_fixed_mode
seems dubious. It's the first non-preferred mode, but there are no
guarantees that the only difference would be refresh rate. Similarly,
there may be more than one preferred mode in the probed modes list, and
the commit changes the preferred mode selection to choose the last one
on the list instead of the first.

(Note that the probed modes list is the raw, unfiltered, unsorted list
of modes from drm_add_edid_modes(), not the pretty result after a
drm_helper_probe_single_connector_modes() call.)

Finally, we already have eerily similar code in place to find the
downclock mode for DRRS that seems like could be reused here.

Back to the drawing board.

Note: This is a hand-crafted revert due to conflicts. If it fails to
backport, please just try reverting the original commit directly.

c7cbed560c drm/gma500: Fix Medfield for drm_framebuffer move 
Commit bc61c97502 ("drm/gma500: Move GEM BO to drm_framebuffer") moved
the gtt_range structure, from being in psb_framebuffer and embedding the
GEM object, to being placed in the drm_framebuffer with the gtt_range
being derived from the GEM object.

The conversion missed out the Medfield subdriver, which was not being
built in the default drm-misc config. Do the trivial fixup here.

drm/tegra: Changes for v4.18-rc1

This set enables IOMMU support in the gr2d and gr3d drivers and adds
support for the zpos property on older Tegra generations. It also
enables scaling filters and incorporates some rework to eliminate a
private wrapper around struct drm_framebuffer.

The remainder is mostly a random assortment of fixes and cleanups, as
well as some preparatory work for destaging the userspace ABI, which
is almost ready and is targetted for v4.19-rc1.

643ca198aa drm: rcar-du: lvds: Fix crash in .atomic_check when disabling connector 
The connector .atomic_check() handler can be called with a NULL crtc
pointer in the connector state when the connector gets disabled
explicitly (through performing a legacy mode set or setting the
connector's CRTC_ID property to 0). This causes a crash as the crtc
pointer is dereferenced without any check.

Fix it by returning from the .atomic_check() handler when then crtc
pointer is NULL, as there is no check to be performed when the connector
gets disabled.

39d3cc03e9 drm/i915/selftests: Wait longer for the old active request 
When testing reset, we wait for 1s on the main thread for the hang to
start. Meanwhile, we continue submitting requests on all the background
threads, and we may have more threads than cores and so potentially
starve the waiter from being woken within the timeout. As the hang
timeout and the active timeouts are the same, it is hard to distinguish
which caused the timeout. Bump the active thread timeouts to 5s,
compared to the 1s timeout for the hang, so that we preferentially
report the hang timing out, while hopefully ensuring that we do at least
wake up the hang thread first before declaring the background active
timeout.

fe0c493538 drm/i915/execlists: Handle copying default context state for atomic reset 
We want to be able to reset the GPU from inside a timer callback
(hardirq context). One step requires us to copy the default context
state over to the guilty context, which means we need to plan in advance
to have that object accessible from within an atomic context. The atomic
context prevents us from pinning the object or from peeking into the
shmemfs backing store (all may sleep), so we choose to pin the
default_state into memory when the engine becomes active. This
compromise allows us to swap out the default state when idle, when
required.

dd0cf235d8 drm/i915: Speed up idle detection by kicking the tasklets 
We rely on ksoftirqd to run in a timely fashion in order to drain the
execlists queue. Quite frequently, it does not. In some cases we may see
latencies of over 200ms triggering our idle timeouts and forcing us to
declare the driver wedged!

Thus we can speed up idle detection by bypassing ksoftirqd in these
cases and flush our tasklet to confirm if we are indeed still waiting
for the ELSP to drain.

v2: Put the execlists.first check back; it is required for handling
reset!

a944744ba5 drm/amd/display: Clear underflow status for debug purposes 
We want to keep underflow sticky bit on for the longevity tests outside
of test environment. For debug purposes it is, however, useful to clear
underflow status after the test that caused it so that the following
tests are not affected. This change fullfils both requirements by clearing
the underflow only from within Windows or Diags test environment.
