Docs: Step-by-step directions for reporting bugs.

REPORTING-BUGS is pretty disorganized.  Bug reporters are likely to be
in a frustrated, stressed frame of mind, so introduce methodical
step-by-step directions for how to report bugs.  Use titles so people
can skim it if necessary.

Slight changes in procedures:

1. Encourage people to report bugs to maintainers and sub-system mailing
lists, not LKML at first.  I've seen way too many people get lost in the
noise because they didn't Cc the maintainer or proper mailing list.

2. Link to bugzilla.kernel.org, and let people know that some
maintainers prefer bugs filed there vs. the mailing lists.  (Perhaps we
need an entry in MAINTAINERS for which is preferred?)

3. If someone doesn't know where to report a bug, encourage them to both
file a bugzilla entry and email LKML.  Their report is less likely to
get lost if there's a bugzilla entry.

Preserve text about reporting security bugs, and get_maintainer.pl.

More will be added/modified in upcoming patches.

Identify the problematic subsystem
----------------------------------
Identifying which part of the Linux kernel might be causing your issue
increases your chances of getting your bug fixed. Simply posting to the
generic linux-kernel mailing list (LKML) may cause your bug report to be
lost in the noise of a mailing list that gets 1000+ emails a day.
Instead, try to figure out which kernel subsystem is causing the issue,
and email that subsystem's maintainer and mailing list. If the subsystem
maintainer doesn't answer, then expand your scope to mailing lists like
LKML.
Identify who to notify
----------------------
Once you know the subsystem that is causing the issue, you should send a
bug report. Some maintainers prefer bugs to be reported via bugzilla
(https://bugzilla.kernel.org), while others prefer that bugs be reported
via the subsystem mailing list.
To find out where to send an emailed bug report, find your subsystem or
device driver in the MAINTAINERS file. Search in the file for relevant
entries, and send your bug report to the person(s) listed in the "M:"
lines, making sure to Cc the mailing list(s) in the "L:" lines. When the
maintainer replies to you, make sure to 'Reply-all' in order to keep the
public mailing list(s) in the email thread.
If you know which driver is causing issues, you can pass one of the driver
files to the get_maintainer.pl script:
perl scripts/get_maintainer.pl -f <filename>
If it is a security bug, please copy the Security Contact listed in the
MAINTAINERS file. They can help coordinate bugfix and disclosure. See
Documentation/SecurityBugs for more information.
If you can't figure out which subsystem caused the issue, you should file
a bug in kernel.org bugzilla and send email to
linux-kernel@vger.kernel.org, referencing the bugzilla URL. (For more
information on the linux-kernel mailing list see
http://www.tux.org/lkml/).

report. This explains what you should do with the "Oops" information to
make it useful to the recipient.
Send the output to the maintainer of the kernel area that seems to be
involved with the problem, and cc the relevant mailing list. Don't worry
too much about getting the wrong person. If you are unsure send it to the
person responsible for the code relevant to what you were doing. If it
occurs repeatably try and describe how to recreate it. That is worth even
more than the oops itself. The list of maintainers and mailing lists is
in the MAINTAINERS file in this directory. If you know the file name that
causes the problem you can use the following command in this directory to
find some of the maintainers of that file:
