So, one model is the one described in the commit message:

What is the other one? I'd expect ARM to already implement a subset of this
(i.e. 0 or negative, perhaps with a subset of the possible errno values), which 
I'd then expect libxc to just cope with without it constituting a second model.

IOW I don't think there should be (or indeed is) any special casing of ARM
vs x86 here or one model vs another, just a case of one arch only using a
subset of the expressibility of the interface.

What have I missed?
