Way back in v3.19 Intel and AMD shared the same machine check severity grading code. So it made sense to add a case for AMD DEFERRED errors in commit e3480271f592 ("x86, mce, severity: Extend the the mce_severity mechanism to handle UCNA/DEFERRED error")
But later in v4.2 AMD switched to a separate grading function in commit bf80bbd7dcf5 ("x86/mce: Add an AMD severities-grading function") Belatedly drop the DEFERRED case from the Intel rule list.
