Thanks for putting this together. I made some minor suggestions below
that might help clarify some points.

We can probably add a reference to it in:

  https://wiki.qemu.org/Contribute/SubmitAPatch

I should probably add a MAINTAINERS entry for stable that references
it too.

Maybe:

"Usually, stable releases are only provided for the last major QEMU
release. For example, when QEMU 2.11.0 is released, 2.11.x or 2.11.x.y
stable releases are only produced until QEMU 2.12.0 is released, at
which the stable process moves to producing 2.12.x/2.12.x.y releases."

"By default, this will send the patch to address@hidden if you use
git send-email, which is where patches that are stable candidates are
tracked by the maintainers."

"You can also reply to a patch and Cc: address@hidden directly with
your mail client if you think a previously submitted patch should be
considered for a stable release."
