Applied 1 to the the fixes-togreg branch of iio.git and
2,3,4 to the togreg branch of iio.git (pushed out as testing only
until I can rebase on rc1).

No overlap in code affected, so this should work fine and means
I don't have to remember to pick up the non fixes later in the cycle.

Thanks,

Jonathan
