Certain MMU virtualization operations in Xen 4.2.x through 4.4.x before the
xsa97-hap patch, when using Hardware Assisted Paging (HAP), are not
preemptible, which allows local HVM guest to cause a denial of service
(vcpu consumption) by invoking these operations, which process every page
assigned to a guest, a different vulnerability than CVE-2014-5149.
