I'd suggest to rename CONFIG_EMBEDDED=y to CONFIG_EXPERT=y, but i'd also 
suggest to rename all sub-config-options that depend on CONFIG_EXPERT to 
have a CONFIG_EXPERT_ prefix.

So we'd have:

  CONFIG_EXPERT_CPU_SUP_INTEL=y
  CONFIG_EXPERT_MMAP_ALLOW_UNINITIALIZED=y

etc.

That way all the enabled 'expert options' become easily visible in the 
.config file and they advertise themselves properly - it's also easily 
greppable. In the source code it also becomes self-documenting, it's 
obvious when a dependency is 'rare' or 'special' - it has a 
CONFIG_EXPERT_ prefix.

Something for the KS i guess.

Thanks,

	Ingo
