RE: [PATCH 4/6] x86-mce: Add spinlocks to prevent duplicated MCP and CMCI reports.

[Luck, Tony]

		if (!(flags & MCP_UC) &&
-		    (m.status & (mca_cfg.ser ? MCI_STATUS_S : MCI_STATUS_UC)))
+		    (m.status & (mca_cfg.ser ? MCI_STATUS_S : MCI_STATUS_UC))) {
+			spin_unlock_irqrestore(&mce_banks[i].poll_spinlock,
+					       irq_flags);
 			continue;
+		}

Perhaps move this test for UC up to before you grab the lock?
