[Qemu-devel] [PATCH 3/7] s390x/ioinst: Throw addressing exception when memory_map failed

[Christian Borntraeger <borntraeger@de.ibm.com>]

From: Thomas Huth <thuth@linux.vnet.ibm.com>

So far, the IO instructions were throwing specification exceptions when
there was a problem with accessing the memory. However, the better way
is to throw an addressing exception instead.
