Why doesn't this use EMBEDDED?

I.e.

	boot "xxx" if EMBEDDED
	default y

style Kconfig.

Only reason which seems reasonable is "this is done only for one pointer
on task_struct". This reason seems something like "You care, but I don't
care it". And, other reasons is *normal* situation on EMBEDDED, right?

Thanks.
