Cornelia Huck 2030511afe KVM: s390: Handle hosts not supporting s390-virtio. commit `55c171a6d9` upstream. Running under a kvm host does not necessarily imply the presence of a page mapped above the main memory with the virtio information; however, the code includes a hard coded access to that page. Instead, check for the presence of the page and exit gracefully before we hit an addressing exception if it does not exist.

Cornelia Huck 2030511afe KVM: s390: Handle hosts not supporting s390-virtio.

commit 55c171a6d9 upstream.

Running under a kvm host does not necessarily imply the presence of
a page mapped above the main memory with the virtio information;
however, the code includes a hard coded access to that page.

Instead, check for the presence of the page and exit gracefully
before we hit an addressing exception if it does not exist.
