ACPI 6.5 added six new error types for CXL. See chapter 18 table 18.30. Add strings for the new types so that Linux will list them in the /sys/kernel/debug/apei/einj/available_error_types file. It seems no other changes are needed. Linux already accepts the CXL codes (on a BIOS that advertises them).
