Subject: [PATCH] stable_kernel_rules: reorganize and update submission options

The current organization of Documentation/stable_kernel_rules.txt
doesn't clearly differentiate the mutually exclusive options for
submission to the -stable review process. As I understand it, patches
are not actually required to be mailed directly to
[email protected], but the instructions do not make this clear.

Also, there are some established processes that are not listed --
specifically, what I call Option 2 below.

This patch updates and reorganizes a bit, to make things clearer.

This patch brough to you as a follow-up of:

https://lkml.org/lkml/2014/9/5/757

I don't profess to know your mind, Greg, but this is my attempt at codifying
what I've observed.

"just" should also have at least the subject of the patch, why you think
it should be applied, and what kernel version you wish it to be applied
to.

Other than the above comments, this looks good, care to redo it?
