Normally the CC tag works. Not entirely sure why it didn't for the one
patch I asked about. The other two commits you've highlighted here are
lacking any sort of stable tag, so you'd have to pipe up here about them.

I went ahead and tried the cherry-pick myself on top of 3.6.9, in the
order you specified above. The 62444b7462a has a trivial conflict coming
back. I've attached an mbox with these three patches. If you want to
give them a glance over and OK them, that would be great.

(Apologies for the attachment. Gmail is going to mess it up otherwise.)

I have them building locally at the moment on top of 3.6.9 and don't
expect many issues, but I can't personally test the fixes myself.
