Also applied, thanks. How about a compat config option for one
or two releases to keep the make oldconfig annoyance down?

This has been previously discussed with Sam or Roman, the end result
being that kbuild does not quite support option fowarding - every
symbol (e.g. OLD_TTL) that has no text will only be enabled if another
symbol references it (thru 'select' for example) and otherwise any
value, even one from .config, will be discarded and set to =n instead.
But when OLD_TTL=n, the 'select NEW_TTL' on OLD_TTL will not take
effect, and so on..

The alternative is to keep the text at the old options and have
them select a new hidden one. After two releases we move the
text over and kill the old ones.

But we really should do something about the constant kconfig
annoyance caused by these renames, let alone people who really
drop an option by accident and start bug hunting.
