  == Comment: #1 - Michael Neuling <michael.neuling@xxxxxxxxxxx> -  ==
  Fix is already upstream.  Need to pull these 4 patches patches from mainline.

  % git log --oneline bf19edd290..eb01d4c238
  eb01d4c cxl: Fix PSL error due to duplicate segment table entries
  03f5439 powerpc/mm: Use appropriate ESID mask in copro_calculate_slb()
  b03a7f5 cxl: Refactor cxl_load_segment() and find_free_sste()
  5100a9d cxl: Disable secondary hash in segment table

  Already fixed upstream, just need Canonical to cherry-pick the 4
  patches.
