Daniel Vetter 85ba7b7d39 Revert "drm/i915: Mask reserved bits in display/sprite address registers" ... This reverts commit 446f254566. I've left the masking in the pageflip code since that seems to be some useful piece of preemptive robustness. Iirc I've merged this patch under the assumption that the BIOS leaves some random gunk in the lower bits and gets unhappy if we trample on them. We have quite a few case like this, so this made sense. Now I've just learned that there's actual hardware features bits in the low 12 bits, and the kernel needs to preserve them to allow a userspace blob to do its job. Given Dave Airlie's clear stance on userspace blob drivers I've quickly chatted with him and he doesn't seem too happy. So let's revert this. If there are indeed bits that we must preserve in this range then we can ressurrect this patch, but with proper documentation for those bits supplied. And we probably also need to think a bit about interactions with our driver.
