From cba7054928b10a7fda57c64807451bbc9a31e42e Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 9 Mar 2015 15:28:37 +0100 Subject: cpus: initialize cpu->memory_dispatch 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.
