Hi Ingo,

while there is a conversation about makeing NMI handler robust/modern or
whatever, I think the naming Huang has implemented for NMI Stat&Ctrl
registers/ports look quite good and convenient (I thought about this times
ago when being merging nmi-32/64 code but didn't implemented it properly).
So I presume perhaps we could merge this snippets first? Or I miss something
on discussion in general?
