I suspect usually the pain is locating all the "lazy" uses of int
rather than addr_t for pointers and fixing them, etc.
Since all the current ports that are in progress are 32-bit (AFAIK),
this hasn't been much of an issue yet.
Ultimately, a 64bit port attempt would help clean this up, of course :)
I'm not an expert, by any means, but I gather from discussions
elsewhere that it can be pretty monotonous work.
