Public bug reported:

There are a few bugfixes upstream that our backport lacks:

 drm/i915: Fix CSR MMIO address check
 drm/i915: Limit the number of loops for reading a split 64bit register
 drm/i915: Always mark the object as dirty when used by the GPU
 drm/i915: Allow DSI dual link to be configured on any pipe
 drm/i915: Preserve SSC earlier
 drm/i915: Check DP link status on long hpd too

the bottom one fixes one OEM bug which also got a BIOS workaround, but a
code fix would be in order for other platforms.
