in x2apic mode. Reads to this MSR are currently ignored but should cause a
general proctection exception to be injected into the vcpu.
All accesses to the corresponding offset in xAPIC mode are ignored.
Also, do not panic the host if there is mismatch between the trigger mode
programmed in the TMR and the actual interrupt being delivered. Instead the
anomaly is logged to aid debugging and to prevent a misbehaving guest from
panicking the host.
