Pull CXL (Compute Express Link) updates from Dan Williams:
 "The highlight is initial support for CXL memory hotplug. The static
  NUMA node (ACPI SRAT Physical Address to Proximity Domain) information
  known to platform firmware is extended to support the potential
  performance-class / memory-target nodes dynamically created from
  available CXL memory device capacity.

  New unit test infrastructure is added for validating health
  information payloads.

  Fixes to module reload stress and stack usage from exposure in -next
  are included. A symbol rename and some other miscellaneous fixups are
  included as well.

  Summary:

   - Rework ACPI sub-table infrastructure to optionally be used outside
     of __init scenarios and use it for CEDT.CFMWS sub-table parsing.

   - Add support for extending num_possible_nodes by the potential
     hotplug CXL memory ranges

   - Extend tools/testing/cxl with mock memory device health information

   - Fix a module-reload workqueue race

   - Fix excessive stack-frame usage

   - Rename the driver context data structure from "cxl_mem" since that
     name collides with a proposed driver name

   - Use EXPORT_SYMBOL_NS_GPL instead of -DDEFAULT_SYMBOL_NAMESPACE at
     build time"
