Pull Compute Express Link (CXL)  updates from Dave Jiang:

 - Add support for Global Persistent Flush (GPF)

 - Cleanup of DPA partition metadata handling:
     - Remove the CXL_DECODER_MIXED enum that's not needed anymore
     - Introduce helpers to access resource and perf meta data
     - Introduce 'struct cxl_dpa_partition' and 'struct cxl_range_info'
     - Make cxl_dpa_alloc() DPA partition number agnostic
     - Remove cxl_decoder_mode
     - Cleanup partition size and perf helpers

 - Remove unused CXL partition values

 - Add logging support for CXL CPER endpoint and port protocol errors:
     - Prefix protocol error struct and function names with cxl_
     - Move protocol error definitions and structures to a common location
     - Remove drivers/firmware/efi/cper_cxl.h to include/linux/cper.h
     - Add support in GHES to process CXL CPER protocol errors
     - Process CXL CPER protocol errors
     - Add trace logging for CXL PCIe port RAS errors

 - Remove redundant gp_port init

 - Add validation of cxl device serial number

 - CXL ABI documentation updates/fixups

 - A series that uses guard() to clean up open coded mutex lockings and
   remove gotos for error handling.

 - Some followup patches to support dirty shutdown accounting:
     - Add helper to retrieve DVSEC offset for dirty shutdown registers
     - Rename cxl_get_dirty_shutdown() to cxl_arm_dirty_shutdown()
     - Add support for dirty shutdown count via sysfs
     - cxl_test support for dirty shutdown

 - A series to support CXL mailbox Features commands.

   Mostly in preparation for CXL EDAC code to utilize the Features
   commands. It's also in preparation for CXL fwctl support to utilize
   the CXL Features. The commands include "Get Supported Features", "Get
   Feature", and "Set Feature".

 - A series to support extended linear cache support described by the
   ACPI HMAT table.

   The addition helps enumerate the cache and also provides additional
   RAS reporting support for configuration with extended linear cache.
   (and related fixes for the series).

 - An update to cxl_test to support a 3-way capable CFMWS

 - A documentation fix to remove unused "mixed mode"
