Linus Torvalds 0c66a95c7e cxl for 5.14
- Add support for the CXL Fixed Memory Window Structure, a recent
   extension of the ACPI CEDT (CXL Early Discovery Table)
 
 - Add infrastructure for component registers
 
 - Add HDM (Host-managed device memory) decoder definitions
 
 - Define a device model for an HDM decoder tree
 
 - Bridge CXL persistent memory capabilities to an NVDIMM bus /
   device-model
 
 - Switch to fine grained mapping of CXL MMIO registers to allow
   different drivers / system software to own individual register blocks
 
 - Enable media provisioning commands, and publish the label storage area
   size in sysfs
 
 - Miscellaneous cleanups and fixes

Pull CXL (Compute Express Link) updates from Dan Williams:
 "This subsystem is still in the build-out phase as the bulk of the
  update is improvements to enumeration and fleshing out the device
  model. In terms of new features, more mailbox commands have been added
  to the allowed-list in support of persistent memory provisioning
  support targeting v5.15.

  The critical update from an enumeration perspective is support for the
  CXL Fixed Memory Window Structure that indicates to Linux which system
  physical address ranges decode to the CXL Host Bridges in the system.
  This allows the driver to detect which address ranges have been mapped
  by firmware and what address ranges are available for future hotplug.

  So, again, mostly skeleton this round, with more meat targeting v5.15.

  Summary:

   - Add support for the CXL Fixed Memory Window Structure, a recent
     extension of the ACPI CEDT (CXL Early Discovery Table)

   - Add infrastructure for component registers

   - Add HDM (Host-managed device memory) decoder definitions

   - Define a device model for an HDM decoder tree

   - Bridge CXL persistent memory capabilities to an NVDIMM bus /
     device-model

   - Switch to fine grained mapping of CXL MMIO registers to allow
     different drivers / system software to own individual register
     blocks

   - Enable media provisioning commands, and publish the label storage
     area size in sysfs

   - Miscellaneous cleanups and fixes"
