TWIMC, I changed a few important things since I wrote above mail. The
most important parts:

* I switched the default flow from "use a shallow clone of linux-stable"
 to "use a full clone of linux-mainline with stable added as remote";
the instructions for shallow clones are now in the reference section, as
it seems that was was some people prefer. Not really happy with that, as
I think the shallow clone stuff was worth it and not that much more
complicated. But whatever, not really unhappy either (maybe I like it a
bit better myself that way, not sure yet). :-D

* I changed a few aspects to make the text properly cover the "verify a
bug is present in mainline" aspect as well, as that's basically the
preparation and segment 1 of the whole process anyway. Not totally sure
if that was a good idea. Maybe having that in a separate copy might have
been better (basically a copy with the segment 2 and 3 removed and a few
small changes), not sure. But that should be easy to realize later.

See above links for details.

Ciao, Thorsten
