#       "It's mostly small bugfixes and cleanups, mostly around x86 nested
#        virtualization.  One important change, not related to nested
#        virtualization, is that the ability for the guest kernel to trap
#        CPUID instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is
#        now masked by default.  This is because the feature is detected
#        through an MSR; a very bad idea that Intel seems to like more and
#        more.  Some applications choke if the other fields of that MSR are
#        not initialized as on real hardware, hence we have to disable the
#        whole MSR by default, as was the case before Linux 4.12."
