Message

Changes for introducing the quick test on the device memory range and
also a test of detailed validation for each addr of the range with read
and write.

Detailed testing is optionally enabled with a modparam i915.memtest=1

And third patch fixes the driver accessible stolen memory.

v2: Adding a wrapper for the memtest [Chris]

Chris Wilson (3):
  drm/i915: Exclude reserved stolen from driver use
  drm/i915: Sanitycheck device iomem on probe
  drm/i915: Test all device memory on probing
