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

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 c2264564 ("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 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.
