      Pull compute express link (cxl) fixes from Dan Williams:
       "Several fixes for driver startup regressions that landed during the
        merge window as well as some older bugs.
      
        The regressions were due to a lack of testing with what the CXL
        specification calls Restricted CXL Host (RCH) topologies compared to
        the testing with Virtual Host (VH) CXL topologies. A VH topology is
        typical PCIe while RCH topologies map CXL endpoints as Root Complex
        Integrated endpoints. The impact is some driver crashes on startup.
      
        This merge window also added compatibility for range registers (the
        mechanism that CXL 1.1 defined for mapping memory) to treat them like
        HDM decoders (the mechanism that CXL 2.0 defined for mapping
        Host-managed Device Memory). That work collided with the new region
        enumeration code that was tested with CXL 2.0 setups, and fails with
        crashes at startup.
      
        Lastly, the DOE (Data Object Exchange) implementation for retrieving
        an ACPI-like data table from CXL devices is being reworked for v6.4.
        Several fixes fell out of that work that are suitable for v6.3.
      
        All of this has been in linux-next for a while, and all reported
        issues [1] have been addressed.
      
        Summary:
      
         - Fix several issues with region enumeration in RCH topologies that
           can trigger crashes on driver startup or shutdown.
      
         - Fix CXL DVSEC range register compatibility versus region
           enumeration that leads to startup crashes
      
         - Fix CDAT endiannes handling
      
         - Fix multiple buffer handling boundary conditions
      
         - Fix Data Object Exchange (DOE) workqueue usage vs
           CONFIG_DEBUG_OBJECTS warn splats"

      Pull iommufd fixes from Jason Gunthorpe:
      
       - An invalid VA range can be be put in a pages and eventually trigger
         WARN_ON, reject it early
      
       - Use of the wrong start index value when doing the complex batch carry
         scheme
      
       - Wrong store ordering resulting in corrupting data used in a later
         calculation that corrupted the batch structure during carry
      
      * tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd:
