** Description changed:

  4.3 will have a bunch of workarounds to fix silicon bugs and other
  bugfixes that need to be backported to both vivid and wily. Some are for
  gen8 chips which also allow cherry-picking the gen9 ones.
  
+  drm/i915/skl WaDisableSbeCacheDispatchPortSharing
+  drm/i915/skl: Don't expose the top most plane on gen9 display
   drm/i915/skl: revert duplicated WaBarrierPerformanceFixDisable:skl
   drm/i915:skl: Add WaEnableGapsTsvCreditFix
   drm/i915/gen9: Add WaSetDisablePixMaskCammingAndRhwoInCommonSliceChicken
   drm/i915/gen9: Add WaFlushCoherentL3CacheLinesAtContextSwitch workaround
   drm/i915: Update wa_ctx_emit() macro as per kernel coding guidelines
   drm/i915/gen9: Add WaDisableCtxRestoreArbitration workaround
   drm/i915: Enable WA batch buffers for Gen9
+  drm/i915/gen9: Implement WaDisableKillLogic for gen 9
   drm/i915: Update WaFlushCoherentL3CacheLinesAtContextSwitch
   drm/i915/gen8: Add WaClearSlmSpaceAtContextSwitch workaround
   drm/i915: Bail out early if WA batch is not available for given Gen
   drm/i915/gen8: Add WaFlushCoherentL3CacheLinesAtContextSwitch workaround
   drm/i915/gen8: Add WaDisableCtxRestoreArbitration workaround
   drm/i915/gen8: Re-order init pipe_control in lrc mode
   drm/i915/gen8: Add infrastructure to initialize WA batch buffers
-  drm/i915: Fix divide by zero on watermark update
