mainline inclusion from mainline-v5.1-rc1 commit 8a5dd2cd2f2e94878cacc969655a69ca214795ab category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4MKP4 CVE: NA
--------------------------------
Some SMCA bank types on future systems will report new error types even though the bank type is not treated as a new version. These new error types will reported by bits that are reserved in past systems.
Add the new error descriptions to the lists in edac_mce_amd.
