It may not be the actual real stable mailing list address, but the
stable scripts to actually pick up on the traditional way to mark stable
patches.
There are also reasons to explicitly avoid using the actual mailing list
address, since security patches with embargo dates generally do want the
stable marking, but don't want tools etc to mistakenly send the patch
out to the mailing list early.
So don't warn for things that are still actively used and explicitly
supported.

Kernel style seems to prefer line wrapping an assignment with the
assignment operator on the previous line like:
<leading tabs> identifier =
expression;
over
<leading tabs> identifier
= expression;
somewhere around a 50:1 ratio
$ git grep -P "[^=]=\s*$" -- "*.[ch]" | wc -l
52008
$ git grep -P "^\s+[\*\/\+\|\%\-]?=[^=>]" | wc -l
1161
So add a --strict test for that condition.

The get_quoted_string function does not expect invalid arguments.
The $stat test can return non-statements for complicated macros like
TRACE_EVENT.
Allow the $stat block and test for vsprintf misuses to exceed the actual
block length and possibly test invalid lines by validating the arguments
of get_quoted_string.
Return "" if either get_quoted_string argument is undefined.
Miscellanea:
o Properly align the comment for the vsprintf extension test

Usage of the new %px specifier potentially leaks sensitive information.
Printing kernel addresses exposes the kernel layout in memory, this is
potentially exploitable. We have tools in the kernel to help us do the
right thing. We can have checkpatch warn developers of potential
dangers of using %px.
Have checkpatch emit a warning for usage of specifier %px.

IMO, we should discourage '---help---' for new help texts, even in cases
where it would be consistent with other help texts in the file. This
will help if we ever want to get rid of '---help---' in the future.
Also simplify the code to only check for exactly '---help---'. Since
commit c2264564df ("kconfig: warn of unhandled characters in Kconfig
commands"), '---help---' is a proper keyword and can only appear in that
form. Prior to that commit, '---help---' working was more of a syntactic
quirk.

Currently, only Kconfig symbols are checked for a missing or short help
text, and are only checked if they are defined with the 'config'
keyword.
To make the check more general, extend it to also check help texts for
choices and for symbols defined with the 'menuconfig' keyword.
This increases the accuracy of the check for symbols that would already
have been checked as well, since e.g. a 'menuconfig' symbol after a help
text will be recognized as ending the preceding symbol/choice
definition.
To increase the accuracy of the check further, also recognize 'if',
'endif', 'menu', 'endmenu', 'endchoice', and 'source' as ending a
symbol/choice definition.

The check for a missing or short help text only considers symbols with a
prompt, but doesn't recognize any of the following as a prompt:
bool 'foo'
tristate 'foo'
prompt "foo"
prompt 'foo'
Make the check recognize those too.

The Analog Devices Blackfin port was added in 2007 and was rather
active for a while, but all work on it has come to a standstill
over time, as Analog have changed their product line-up.
Aaron Wu confirmed that the architecture port is no longer relevant,
and multiple people suggested removing blackfin independently because
of some of its oddities like a non-working SMP port, and the amount of
duplication between the chip variants, which cause extra work when
doing cross-architecture changes.
