This patch series fixes a number of minor Neon bugs, mostly related to edge cases involving NaN handling.
The patch series includes adding support for float*_min() and float*_max() operations to softfloat, because this makes it easy to get NaN propagation and handling of zeroes correct. I've only added support for float32 and float64 versions because I think the implementation is complex enough that there's no point providing an untested and unused version for float128. (floatx80 doesn't even implement the comparison ops so min/max is definitely a stretch there.) I note in passing that patch 6 (the softfloat one) seems to hang scripts/checkpatch.pl, or at least make it take an unreasonably long time to finish...
