Btw, for all structure types you define, and with your desire to avoid
compat mode translation, you should add ?-prefixed entries to
xen/include/xlat.lst and invoke the produced CHECK_* macros from
somewhere. If, for reference, you'd look at existing instances, you'll
then also find another reason why all these would better have xen_
prefixes.
