From: Aravind Gopalakrishnan <Aravind.Gopalakrishnan@amd.com> Deferred errors indicate errors that hardware could not fix. But it still does not cause any interruption to program flow. So it does not generate any #MC and UC bit in MCx_STATUS is not set. Correct comment. Signed-off-by: Aravind Gopalakrishnan <Aravind.Gopalakrishnan@amd.com> Cc: "H.
