Not sure you really need to mention commit hashes from outside of the
mainline Linux tree and the values I added to that commit were probably
copied from some patch originating from ARM or elsewhere anyway. So the
second paragraph is this commit message is probably superfluous. But
this is nitpicking I guess :-)
