-Subject: [PATCH] net: mcf: limit buffer descriptor count
-
-ColdFire Fast Ethernet Controller uses buffer descriptors to manage
-data flow to/fro receive & transmit queues. While transmitting
-packets, it could continue to read buffer descriptors if a buffer
-descriptor has length of zero and has crafted values in bd.flags.
-Set upper limit to number of buffer descriptors.

-Subject: [PATCH] net: pcnet: check rx/tx descriptor ring length
-
-The AMD PC-Net II emulator has set of control and status(CSR)
-registers. Of these, CSR76 and CSR78 hold receive and transmit
-descriptor ring length respectively. This ring length could range
-from 1 to 65535. Setting ring length to zero leads to an infinite
-loop in pcnet_rdra_addr() or pcnet_transmit(). Add check to avoid it.

+Subject: [Qemu-ppc] [PATCH 1/1] target-ppc, tcg: fix usermode segfault with pthread_create()
+Date: Mon, 30 Jan 2017 16:08:07 +1100
+Programs run under qemu-ppc64 on an x86_64 host currently segfault
+if they use pthread_create() due to the adjustment made to the NIP in
+commit bd6fefe71cec5a0c7d2be4ac96307f25db56abf9.
+
+This patch changes cpu_loop() to set the NIP back to the
+pre-incremented value before calling do_syscall(), which causes the
+correct address to be used for the new thread and corrects the fault.
