KVM: VMX: Add non-canonical check on writes to RTIT address MSRs

Browse Source

[ Upstream commit fe6ed369fc ]

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().
