Pull CXL (Compute Express Link) updates from Dan Williams:
 "The main new functionality this time is work to allow Linux to
  natively handle CXL link protocol errors signalled via PCIe AER for
  current generation CXL platforms. This required some enlightenment of
  the PCIe AER core to workaround the fact that current generation RCH
  (Restricted CXL Host) platforms physically hide topology details and
  registers via a mechanism called RCRB (Root Complex Register Block).

  The next major highlight is reworks to address bugs in parsing region
  configurations for next generation VH (Virtual Host) topologies. The
  old broken algorithm is replaced with a simpler one that significantly
  increases the number of region configurations supported by Linux. This
  is again relevant for error handling so that forward and reverse
  address translation of memory errors can be carried out by Linux for
  memory regions instantiated by platform firmware.

  As for other cross-tree work, the ACPI table parsing code has been
  refactored for reuse parsing the "CDAT" structure which is an
  ACPI-like data structure that is reported by CXL devices. That work is
  in preparation for v6.8 support for CXL QoS. Think of this as dynamic
  generation of NUMA node topology information generated by Linux rather
  than platform firmware.

  Lastly, a number of internal object lifetime issues have been resolved
  along with misc. fixes and feature updates (decoders_committed sysfs
  ABI).

  Summary:

   - Add support for RCH (Restricted CXL Host) Error recovery

   - Fix several region assembly bugs

   - Fix mem-device lifetime issues relative to the sanitize command and
     RCH topology.

   - Refactor ACPI table parsing for CDAT parsing re-use in preparation
     for CXL QOS support"
