Is it possible for non-owners of a kernel.org account to do this?

Yes, kernel.org runs the git daemon.

Excellent!  I have a faint memory of hpa recently saying that the git
daemon would be too resource-hungry.  One of the cases where being
wrong is a Good Thing.

Well, .git/objects for your kernel still consumes 121M.  It's not
gigabytes but I still wouldn't want too many copies of that lying
around.

Right. However, these days we have better approaches than 
GIT_OBJECT_DIRECTORY for that.

In particular, if you create local clones, use "git clone -l -s", which 
shares its base objects with the thing you clone from. It makes the clone 
incredibly fast too (the only real cost is the check-out, which can 
obviously be pretty expensive), and you can then use

	git repack -a -d -l

on all the to repack just the _local_ objects to avoid having packs 
duplicate objects unnecessarily.

This still isn't good enough for me.  Before git, all my trees were
hard-linked (cowlinked, actually) and another copy barely consumed any
space.  "git clone -l -s"  creates a copy of the currently 311M of
kernel source, quite a bit more expensive.

But it appears as if I could "cp -lr" the git tree and work with that.
The nice thing of having cowlinks is that I don't have to rely on git
breaking the hard links - which it probably won't.  But since the
estimated user base of cowlinks is 1, that won't help too many people.
