Yes, that's what it is. Interestingly they avoided some of the huge
mistakes of x32, but I think that was largely a consequence of having
most or all of the kernel n32 types match the plain 32-bit types
(sadly including, if I'm not mistaken, 32-bit time_t) rather than
being a crazy mix. Someone who knows n32 better could probably clarify
this.

If I remember correctly, the Loongson mips64-based laptops use n32,
probably because mips is painfully underpowered for a laptop/desktop
even without doubling the memory bus pressure with 64-bit pointers.
