This was somehow lost between v3 and the merged version in Maarten's
patch merged as:
commit f2d580b9a8149735cbc4b59c4a8df60173658140
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date: Wed May 4 14:38:26 2016 +0200
drm/core: Do not preserve framebuffer on rmfb, v4.
Actual code copied from Maarten's patch, but with the slight change to
just use dev->mode_config.funcs->atomic_commit to decide whether to
use the atomic path or not.

This effectively reverts
commit afcd950cafea6e27b739fe7772cbbeed37d05b8b
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date: Wed Jun 10 15:58:01 2015 +0100
drm: Avoid the double clflush on the last cache line in drm_clflush_virt_range()
as we have observed issues with serialisation of the clflush operations
on Baytrail+ Atoms with partial updates. Applying the double flush on the
last cacheline forces that clflush to be ordered with respect to the
previous clflush, and the mfence then protects against prefetches crossing
the clflush boundary.
The same issue can be demonstrated in userspace with igt/gem_exec_flush.
Fixes: afcd950cafea6 (drm: Avoid the double clflush on the last cache...)

System workqueues have been able to handle high level of concurrency
for a long time now and there's no reason to use dedicated workqueues
just to gain concurrency. Since the workqueue in the QXL graphics device
driver is involved in freeing and processing the release ring
(workitem &qdev->gc_workqxl, maps to gc_work which calls
qxl_garbage_collect) and is not being used on a memory reclaim path,
dedicated gc_queue has been replaced with the use of system_wq.
Unlike a dedicated per-cpu workqueue created with create_workqueue(),
system_wq allows multiple work items to overlap executions even on
the same CPU; however, a per-cpu workqueue doesn't have any CPU
locality or global ordering guarantees unless the target CPU is
explicitly specified and thus the increase of local concurrency
shouldn't make any difference.
flush_work() has been called in qxl_device_fini() to ensure that there
are no pending tasks while disconnecting the driver.

Consolidate the _DRM_VBLANK_NEXTONMISS handling between drm_wait_vblank
and drm_queue_vblank_event.
This is a cleanup spotted while working on other changes.
(The way it was previously handled could also theoretically result in
drm_queue_vblank_event unnecessarily bumping vblwait->request.sequence,
if the vblank counter happened to increment between the
drm_vblank_count(_and_time) calls in each function, but that's unlikely)

One of the numerous VT-d workarounds we require is that the display
hardware reads past the end of the buffer triggering VT-d faults. This
is acknowledged in the code as being safe "since we fill the unused
portions of the GGTT with the scratch page". Alas, that is no longer
always true and so we trigger DMAR read faults.
Skylake also requires another workaround to avoid mixing VT-d and
unpopulated PTE, and so there we also need to ensure we fill unused
entries with the scratch page.
