Looks much more better now, thanks. Not that I'm somehow happy with the
long usages there, but that's a separate issue, see below.

I see you are removing all that windows-named type crap. Do you plan to
remove also this evil? I mean s/QWORD/u64/ and fix its users
appropriately. And then remove this UQuadWord thing altogether.
And may I suggest adding a line to the bottom of TODO for these drivers
mentioning that someone should revisit unsigned long usage and try to
lower .data footprint significantly?
thanks,
