      Pull cxl fixes from Dan Williams:
       "Several fixes for CXL region creation crashes, leaks and failures.
      
        This is mainly fallout from the original implementation of dynamic CXL
        region creation (instantiate new physical memory pools) that arrived
        in v6.0-rc1.
      
        Given the theme of "failures in the presence of pass-through decoders"
        this also includes new regression test infrastructure for that case.
      
        Summary:
      
         - Fix region creation crash with pass-through decoders
      
         - Fix region creation crash when no decoder allocation fails
      
         - Fix region creation crash when scanning regions to enforce the
           increasing physical address order constraint that CXL mandates
      
         - Fix a memory leak for cxl_pmem_region objects, track 1:N instead of
           1:1 memory-device-to-region associations.
      
         - Fix a memory leak for cxl_region objects when regions with active
           targets are deleted
      
         - Fix assignment of NUMA nodes to CXL regions by CFMWS (CXL Window)
           emulated proximity domains.
      
         - Fix region creation failure for switch attached devices downstream
           of a single-port host-bridge
      
         - Fix false positive memory leak of cxl_region objects by recycling
           recently used region ids rather than freeing them
      
         - Add regression test infrastructure for a pass-through decoder
           configuration
      
         - Fix some mailbox payload handling corner cases"

       "Fix two regressions:
      
         - Commit 54cc3dbf ("hwmon: (pmbus) Add regulator supply into
           macro") resulted in regulator undercount when disabling regulators.
           Revert it.
      
         - The thermal subsystem rework caused the scmi driver to no longer
           register with the thermal subsystem because index values no longer
           match. To fix the problem, the scmi driver now directly registers
           with the thermal subsystem, no longer through the hwmon core"
