[PATCH 1/1] Use cachable mapping for i915 opregion.

2011-01-24 Thread Michael Karcher
The opregion is a shared memory region between ACPI and the graphics driver. As the ACPI mapping has been changed to cachable in commit 6d5bbf00d251cc73223a71422d69e069dc2e0b8d, mapping the intel opregion non-cachable now fails. As no bus-master hardware is involved in the opregion, cachable map sh
