xen-kernel -- VMX: intercept issue with INVLPG on non-canonical address
The Xen Project reports: While INVLPG does not cause a General Protection Fault when used on a non-canonical address, INVVPID in its "individual address" variant, which is used to back the intercepted INVLPG in certain cases, fails in such cases. Failure of INVVPID results in a hypervisor bug...
