Patch Set #3, Line 214: return Reg'Enum_Rep + Config.Display_Base_Offset / Register_Width;
I can't see any. I've added a comment, though.
Oh, looks like the EMGD people already wrote the function we would need:
static bool IS_DISPLAYREG(u32 reg)
{
/*
* This should make it easier to transition modules over to the
* new register block scheme, since we can do it incrementally.
*/

Yeah, no. That thing is huge.
