RE: [PATCH] x86/mce: Pay no attention to 'F' bit in MCACOD whenparsing 'UC' errors.

[Luck, Tony]

	MCESEV(
+		PANIC, "Action required but kernel thread is not continuable",
+		SER, MASK(MCI_STATUS_OVER|MCI_UC_SAR|MCI_ADDR, MCI_UC_SAR|MCI_ADDR),
+		MCGMASK(MCG_STATUS_RIPV|MCG_STATUS_EIPV, MCG_STATUS_RIPV|MCG_STATUS_EIPV),
+		KERNEL
+		),
+	MCESEV(
 		AR, "Action required: data load error in a user process",
 		SER, MASK(MCI_STATUS_OVER|MCI_UC_SAR|MCI_ADDR|MCACOD, MCI_UC_SAR|MCI_ADDR|MCACOD_DATA),
 		USER

This just gives us a better panic message. Right?  Without this we'd keep walking the
severity table until we hit the "Action required: unknown MCACOD" entry which will
match and force a panic anyway.

So I might look for better wording.  As far as the h/w is concerned the thread is continuable.
Linux is just not smart enough (yet) to take the required recovery action.
