In 2.4.2-ac18 there are 130 CONFIG options that are always derived from
other options, the user has no control over them. It is useful for the
kernel build process to know which variables are derived and which
variables the user can control. There are also 6 CONFIG options that
are not used anywhere.
ftp://ftp.ocs.com.au/pub/2.4.2-ac18-config_derived.gz
is a 583,904 byte (unzipped) 114,291 (gzipped) patch which removes the
unused variables and renames the 130 derived variables from CONFIG_FOO
to CONFIG_FOO_DERIVED. The affected variables are :-
Removed. There were a couple more that could have been removed because
nothing checks them, but they identify architecture types in .config
and are useful for bug reporting.
