I wonder if ADDR_LIMIT_128T would be clearer?

I don't follow, what does 128T represent?

128T is 128 Terabytes, that's the maximum size achievable with a 47BIT
address, that naming would be more consistant with the ADDR_LIMIT_3GB
just above that means a 3 Gigabytes limit.

Hence ADDR_LIMIT_128TB?

Yes it should be 128TB. Typo by me.

cheers
