It is unlikely that L1 will toggle the MSR intercept bit in vmcb02,
or that L1 will change its own IA32_PAT MSR. However, if it does,
the affected fields in vmcb02 should not be marked clean.

An alternative approach would be to implement a set of mutators for
vmcb02 fields, and to clear the associated clean bit whenever a field
is modified.
