Subject: [PATCH v2 0/1] cxl/cli: HPA-ordered destroy-region teardown

This is v2 of the series.

Changes since v1:
 - Rework teardown ordering to account endpoint decoders shared across
   regions under the same bus/port
 - This addresses scenario described by Alison when a memdev is
   targeted by regions under multiple root decoders.

Alison, if you have a chance, could you please retest this version
against your multi-root-decoder configuration to confim that the
teardown now behaves correctly in that scenario?

  cxl/cli: enforce HPA-descening teardown order for destroy-region
