Subject: [PATCH] kconfig: announce removal of oldnoconfig if used

The 'oldnoconfig' is really confusing due to its counter-intuitive name.
It was renamed by commit fb16d8912db5 ("kconfig: replace 'oldnoconfig'
with 'olddefconfig', and keep the old name as an alias").

The 'oldnoconfig' has been kept as an alias for enough period of time,
and finally I am planning to remove it. Meanwhile, the following
message will be displayed if oldnoconfig is used.

WARNING: "oldnoconfig" target will be removed after Linux 4.19
Please use "olddefconfig" instead.

Maybe it could be extended to "Please use \"olddefconfig\" instead,
which is an alias", to make it extra clear.

Guessing "no" is from the fact that bool/tristate symbols with no user
value default to n unless they're selected or have an active default.
Confusing name still.

Cheers,
Ulf

I did so, and applied to linux-kbuild/kconfig.
