Subject: [PATCH 01/12] mce-severity: fixes for mce severity table

From: Tony Luck <tony.luck@...el.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.
