A pile of small fixes:

- don't quote terms like vanilla, mainline, and stable, unless in they
  occur in places where readers new to the kernel might see them for the
  first time

- make people rule out that vendor patches are interfering if they face
  a regression in a stable or longterm kernel they saw in a vendor
  kernel for the first time

- s/bugs/issues/ in a selected spots

- exchange two headlines that got mixed up somehow

- add a few links to some of the steps in the guide

- Greg mentioned sending reports to the stable mailing list is
  sufficient, so remove the "CC stable maintainers" bits

- fix a few typos and mistakes in the text, with a few very small
  improvements along the way

Currently, kernel-doc start parsing the comment as a kernel-doc comment if
it starts with '/**', but does not take into account if the content inside
the comment too, adheres with the expected format.
This results in unexpected and unclear warnings for the user.

E.g., running scripts/kernel-doc -none mm/memcontrol.c emits:
"mm/memcontrol.c:961: warning: expecting prototype for do not fallback to current(). Prototype was for get_mem_cgroup_from_current() instead"

Here kernel-doc parses the corresponding comment as a kernel-doc comment
and expects prototype for it in the next lines, and as a result causing
this warning.

Provide a clearer warning message to the users regarding the same, if the
content inside the comment does not follow the kernel-doc expected format.

Right now, if one of the following headers end with a '::', the
kernel-doc script will do the wrong thing:

	description|context|returns?|notes?|examples?

The real issue is with examples, as people could try to write
something like:

	example::

		/* Some C code */

and this won't be properly evaluated. So, improve the regex
to not catch '\w+::' regex for the above identifiers.

Provide a shorter and easier process for users that deal with
regressions in stable and longterm kernels, as those should be reported
quickly.

To realize this in the least-confusing way and without having steps
multiple times in different places, split the 'search for existing
reports' into two. That has the additinal benefit that users will search
for them quickly when going through the step by step guide and thus will
save them trouble if the find reports.
