-[Qemu-ppc] [PATCH 1/1] target-ppc, tcg: fix usermode segfault with pthread

-From: Sam Bobroff
-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.
