[S390] kvm: handle tprot intercepts
When running a kvm guest we can get intercepts for tprot, if the host page table is read-only or not populated. This patch implements the most common case (linux memory detection). This also allows host copy on write for guest memory on newer systems. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
