Intel posts a new "Xe" graphics driver

Intel's graphical processors have been well supported in the mainline for
years, but it seems that the i915 driver may be approaching the end of its
development life. Matthew Brost has just posted a new
driver called 'Xe' that looks to be (eventually) a replacement for
i915:

The intention of this new driver is to have a fresh base to work
from that is unencumbered by older platforms, whilst also taking
the opportunity to rearchitect our driver to increase sharing
across the drm subsystem, both leveraging and allowing us to
contribute more towards other shared components like TTM and
drm/scheduler.
