Bug Description

Problem Description
CXL: Fix PSL error due to duplicate segment table entries

---uname output---

Machine Type = POWER8 + CAPI card

 stress test surelock application with HTX

== Comment: #1 - Michael Neuling <email address hidden> - ==
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.
