From 2450cf51a1bdba7037e91b1bcc494b01c58aaf66 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 2 Mar 2009 16:23:33 -0800 Subject: [PATCH] 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).
