X-Git-Tag: v3.9-rc1~97^2~90 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=55c171a6d90dc0574021f9c836127cfd1a7d2e30;p=pandora-kernel.git KVM: s390: Handle hosts not supporting s390-virtio. 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.
