BugLink: https://bugs.launchpad.net/bugs/1864775 [ Upstream commit fe6ed369 ] Reject writes to RTIT address MSRs if the data being written is a non-canonical address as the MSRs are subject to canonical checks, e.g. KVM will trigger an unchecked #GP when loading the values to hardware during pt_guest_enter().
