An issue was discovered in Xen through 4.11.x allowing 64-bit PV guest OS
users to cause a denial of service (host OS crash) because #GP[0] can occur
after a non-canonical address is passed to the TLB flushing code. NOTE:
this issue exists because of an incorrect CVE-2017-5754 (aka Meltdown)
mitigation.
