[PATCH 5.10 543/575] x86/mce: Add errata workaround for Skylake SKX37

[Greg Kroah-Hartman]

From: Dave Jones <davej@xxxxxxxxxxxxxxxxx>

commit e629fc1407a63dbb748f828f9814463ffc2a0af0 upstream.

Errata SKX37 is word-for-word identical to the other errata listed in
this workaround.   I happened to notice this after investigating a CMCI
storm on a Skylake host.  While I can't confirm this was the root cause,
spurious corrected errors does sound like a likely suspect.

Fixes: 2976908e4198 ("x86/mce: Do not log spurious corrected mce errors")
