+From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
+From: Prarit Bhargava <prarit@redhat.com>
+Date: Thu, 11 Jun 2020 21:03:36 -0400
+Subject: [PATCH] arch/x86: Remove vendor specific CPU ID checks
+
+Upstream Status: RHEL only
+
+After discussions with Devel, QE, Support, and Certification we have
+decided to drop the CPU specific checks in rh_check_supported().
+Certification is adopting a new process in which CPU certifications will
+be tracked on https://catalog.redhat.com.
+
+Remove the vendor specific CPU ID checks from rh_check_supported().
+
