[Qemu-devel] [PULL 06/11] cpus: initialize cpu->memory_dispatch

From: Paolo Bonzini
Subject: [Qemu-devel] [PULL 06/11] cpus: initialize cpu->memory_dispatch
Date: Tue, 10 Mar 2015 11:37:55 +0100

This fixes a NULL pointer dereference in s390x-softmmu.

On pretty much all other architectures, creating an MMIO region calls
cpu_reload_memory_map.  On s390, however, there are no MMIO regions
and everything is done via hypercalls.

Fixes: 9d82b5a792236db31a75b9db5c93af69ac07c7c5
