Linus Torvalds e62f81bbd2 CXL for v6.11 merge window
New Changes:
 - Refactor to a common struct for DRAM and general media CXL events
 - Add abstract distance calculation support for CXL
 - Add CXL maturity map documentation to detail current state of CXL enabling
 - Add warning on mixed CXL VH and RCH/RCD hierachy to inform unsupported config
 - Replace ENXIO with EBUSY for inject poison limit reached via debugfs
 - Replace ENXIO with EBUSY for inject poison cxl-test support
 - XOR math fixup for DPA to SPA translation. Current math works for MODULO arithmetic
   where HPA==SPA, however not for XOR decode.
 - Move pci config read in cxl_dvsec_rr_decode() to avoid unnecessary acess
 
 Fixes:
 - Add a fix to address race condition in CXL memory hotplug notifier
 - Add missing MODULE_DESCRIPTION() for CXL modules
 - Fix incorrect vendor debug UUID define

Pull CXL updates from Dave Jiang:
 "Core:

   - A CXL maturity map has been added to the documentation to detail
     the current state of CXL enabling.

     It provides the status of the current state of various CXL features
     to inform current and future contributors of where things are and
     which areas need contribution.

   - A notifier handler has been added in order for a newly created CXL
     memory region to trigger the abstract distance metrics calculation.

     This should bring parity for CXL memory to the same level vs
     hotplugged DRAM for NUMA abstract distance calculation. The
     abstract distance reflects relative performance used for memory
     tiering handling.

   - An addition for XOR math has been added to address the CXL DPA to
     SPA translation.

     CXL address translation did not support address interleave math
     with XOR prior to this change.

  Fixes:

   - Fix to address race condition in the CXL memory hotplug notifier

   - Add missing MODULE_DESCRIPTION() for CXL modules

   - Fix incorrect vendor debug UUID define

  Misc:

   - A warning has been added to inform users of an unsupported
     configuration when mixing CXL VH and RCH/RCD hierarchies

   - The ENXIO error code has been replaced with EBUSY for inject poison
     limit reached via debugfs and cxl-test support

   - Moving the PCI config read in cxl_dvsec_rr_decode() to avoid
     unnecessary PCI config reads

   - A refactor to a common struct for DRAM and general media CXL
     events"
