+Subject: genirq: Allow irq_chip registration functions to take a const
+ irq_chip
+
+From: Marc Zyngier <maz@kernel.org>
+
+[ Upstream commit 393e1280f765661cf39785e967676a4e57324126 ]
+
+In order to let a const irqchip be fed to the irqchip layer, adjust
+the various prototypes. An extra cast in irq_set_chip()() is required
+to avoid a warning.

+Subject: netfilter: ipset: Add list flush to cancel_gc
+
+From: Alexander Maltsev <keltar.gw@gmail.com>
+
+[ Upstream commit c1193d9bbbd379defe9be3c6de566de684de8a6f ]
+
+Flushing list in cancel_gc drops references to other lists right away,
+without waiting for RCU to destroy list. Fixes race when referenced
+ipsets can't be destroyed while referring list is scheduled for destroy.
