Is it useful (and correct?) to say that the Linux kernel, built for MIPS32r5, by default expect the 2008 NaN encoding?

It is correct, but since nan2008 is the default I think is not worth mentioning it. If you change the default value is because you know what you are doing, right?

Both applied, thanks!
Have you had the chance to look at the -mnan issue with old gcc versions ? This is currently making the autobuilders quite noisy, which isn't nice.
Thanks!
