So the version I have of this in linux-next has not been updated since
Dec 2 and is based on v4.4-rc1.  The version above is based on
v4.4-rc6 and has extra commits ... Did someone forget to update the
xen-tip/linux-next branch?

Yes.

Ideally I'd like the linux-next branch in ../xen/tip.git to be symbolic
reference to the current for-linus-x.y branch so I do not have to
remember to push to two different branches.  I can't see a way to do
this though.

You're using tags for the pull request though, so do you need the for-linus-x.y
branch at all?

I've stopped using them, and instead just push to next and ask Linus to pull
a tag. That also avoids any possibility of the for-linus-x.y branch getting out
of sync with the for-linus-x.y tag.
