drm: Restore double clflush on the last partial cacheline
...
This effectively reverts
commit afcd950cafchris@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.

drm/qxl: Remove deprecated create_singlethread_workqueue
...
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.
