Linus Torvalds d104e3d17f CXL changes for v6.18
Misc changes:
 - Use str_plural() instead of open code for emitting strings.
 - Use str_enabled_disabled() instead of ternary operator
 - Fix emit of type resource_size_t argument for validate_region_offset()
 - Typo fixup in CXL driver-api documentation
 - Rename CFMWS coherency restriction defines
 - Add convention doc describe dealing with x86 low memory hole and CXL
 
 Poison Inject support series:
 - Move hpa_to_spa callback to new reoot decoder ops structure
 - Define a SPA to HPA callback for interleave calculation with XOR math
 - Add support for SPA to DPA address translation with XOR
 - Add locked variants of poison inject and clear functions
 - Add inject and clear poison support by region offset
 
 CXL access coordinates update fix series:
 - A comment update for hotplug memory callback prority defines
 - Add node_update_perf_attrs() for updating perf attrs on a node
 - Update cxl_access_coordinates() to use the new node update function
 - Remove hmat_update_target_coordinates() and related code
 
 CXL delayed downstream port enumeration and initialization series
 - Add helper to detect top of CXL device topology and remove open coding
 - Add helper to delete single dport
 - Add a cached copy of target_map to cxl_decoder
 - Refactor decoder setup to reduce cxl_test burden
 - Defer dport allocation for switch ports
 - Add mock version of devm_cxl_add_dport_by_dev() for cxl_test
 - Adjust the mock version of devm_cxl_switch_port_decoders_setup() due to
   cxl core usage

Pull CXL updates from Dave Jiang:
 "The changes include adding poison injection support, fixing CXL access
  coordinates when onlining CXL memory, and delaing the enumeration of
  downstream switch ports for CXL hierarchy to ensure that the CXL link
  is established at the time of enumeration to address a few issues
  observed on AMD and Intel platforms.

  Misc changes:
   - Use str_plural() instead of open code for emitting strings.
   - Use str_enabled_disabled() instead of ternary operator
   - Fix emit of type resource_size_t argument for
     validate_region_offset()
   - Typo fixup in CXL driver-api documentation
   - Rename CFMWS coherency restriction defines
   - Add convention doc describe dealing with x86 low memory hole
     and CXL

  Poison Inject support:
