Subject: [PATCH 01/10] MCE: fixes for mce severity table
Date: Thu, 09 Jun 2011 14:29:41 -0700 [thread overview]
Message-ID: <4df13b45272441cfb0@agluck-desktop.sc.intel.com> (raw)
In-Reply-To: <4df13a522720782e51@agluck-desktop.sc.intel.com>
From: Tony Luck <tony.luck@intel.com>
The "Spurious not enabled" entry is redundant. The "Not enabled"
entry earlier in the table will cover this case.
The "Action required; unknown MCACOD" entry shouldn't specify
MCACOD in the .mask field. Current code will only match for
mcacod==0 rather than all AR=1 entries.
