      drm/i915: Add GEN7_PCODE_MIN_FREQ_TABLE_GT_RATIO_OUT_OF_RANGE to SNB · fc2780b6
      Chris Wilson authored
      According to the CI test machines, SNB also uses the
      GEN7_PCODE_MIN_FREQ_TABLE_GT_RATIO_OUT_OF_RANGE value to report a bad
      GEN6_PCODE_MIN_FREQ_TABLE request.

      drm/imx: Add active plane reconfiguration support · c6c1f9bc
      Liu Ying authored
      We don't support configuring active plane on-the-fly for imx-drm.
      The relevant CRTC should be disabled before the plane configuration.
      Of course, the plane itself should be disabled as well.
      This patch adds active plane reconfiguration support by forcing CRTC
      mode change and disabling-enabling plane in plane's ->atomic_update
      callback.

      drm/i915/dvo: Remove dangling call to drm_encoder_cleanup() · 8a07fed4

       "Round one of 4.8 rc fixes.
      
        This should be the bulk of the -rc fixes for 4.8.  I only have a few
        things that are still outstanding (two ipoib bugs for which the
        solution is not yet fully known, and a few queued items that came in
        after my last push and I didn't want to delay this pull request for
        late comers again).
      
        Even though the patch count is kind of high, everything is minor fixes
        so the overall churn is pretty low.
      
        Summary:
      
         - minor fixes to cxgb4
         - minor fixes to mlx4
         - one minor fix each to core, rxe, isert, srpt, mlx5, ocrdma, and usnic
         - six or so fixes to i40iw fixes
         - the rest are hfi1 fixes"

      mm: silently skip readahead for DAX inodes · 11bd969f
      Ross Zwisler authored
      For DAX inodes we need to be careful to never have page cache pages in
      the mapping->page_tree.  This radix tree should be composed only of DAX
      exceptional entries and zero pages.
      
      ltp's readahead02 test was triggering a warning because we were trying
      to insert a DAX exceptional entry but found that a page cache page had
      already been inserted into the tree.  This page was being inserted into
      the radix tree in response to a readahead(2) call.
      
      Readahead doesn't make sense for DAX inodes, but we don't want it to
      report a failure either.  Instead, we just return success and don't do
      any work.
