+Subject: [PATCH] cciss: Add IRQF_SHARED back in for the non-MSI(X) interrupt
+ handler
+
+commit 6225da481597ebff09454c785fe0afc7f5fdbb77 upstream.
+
+IRQF_SHARED is required for older controllers that don't support MSI(X)
+and which may end up sharing an interrupt.
+
+Also remove deprecated IRQF_DISABLED.
