Revert "menu: fix embedded menu snafu"
This reverts commit 155b25bcc28631a5b5230191aa3f56c40dfffa3f, which was totally wrong - the "embedded" options still exists (very much so) even on non-embedded platforms. It's just that we don't bother with actually asking about them when we're not embedded, we just take their default values (which is usually 'y' - the options add features that may not be worth it in a constrained environment). Noticed-by: Andrew Morton <akpm@linux-foundation.org> Cc: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
