These are located in the 'if MODULES' ... 'endif' block.

When CONFIG_MODULES is disabled, CONFIG_UNUSED_SYMBOLS is pointless,
thus it should be invisible.
Instead of adding "depends on MODULES", I moved it to the sub-menu
"Enable loadable module support", which is a better fit. I put it
close to TRIM_UNUSED_KSYMS because it depends on !UNUSED_SYMBOLS.

Could you queue these two patches to your tree?

Ah, I thought they were going to the kbuild tree. But yes, I'll take
them through modules-next.
Thanks,
