Hi Mark,

assuming that this is targeted at v3.20 then it looks like your
changes do not conflict with anything I have queued up and
I am not likely to queue anything more up for the files in question
for that release. As my main concern is about conflicts I'm therefore
quite happy for you to take the shmobile patch through your tree.
I'll supply an ack accordingly.
