Merge tag 'drm-intel-fixes-2013-10-21' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes

Just an lvds clock gating fix and a pte clearing hack for hsw to avoid memory corruption when hibernating - something doesn't seem to switch off properly, we're still investigating. * tag 'drm-intel-fixes-2013-10-21' of git://people.freedesktop.org/~danvet/drm-intel: (96 commits) drm/i915: Disable GGTT PTEs on GEN6+ suspend drm/i915: Make PTE valid encoding optional drm/i915: disable LVDS clock gating on CPT v2
