Merge tag 'v3.6-rc7' into drm-intel-next-queued

Manual backmerge of -rc7 to resolve a silent conflict leading to compile failure in drivers/gpu/drm/i915/intel_hdmi.c. This is due to the bugfix in -rc7: commit b98b601 Author: Wang Xingchao <xingchao.wang@intel.com> Date: Thu Sep 13 07:43:22 2012 +0800 drm/i915: HDMI - Clear Audio Enable bit for Hot Plug Since this code moved around a lot in -next git put that snippet at the wrong spot. I've tried to fix this by making the conflict explicit by merging a version for next with: commit 3cce574 Author: Wang Xingchao <xingchao.wang@intel.com> Date: Thu Sep 13 11:19:00 2012 +0800 drm/i915: HDMI - Clear Audio Enable bit for Hot Plug unconditionally But that failed to solve the entire problem. To avoid pushing out further -nightly branch to our QA where this is broken, do the backmerge and manually add the stuff git adds to -next from the patch in -fixes. Note that this doesn't show up in git's merge diff (and hence is also not handled by git rerere), which adds to the reasons why I'd like to fix this with a verbose backmerge. The git merge diff only shows a bunch of trivial conflicts of the "code changed in lines next to each another" kind. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
